DESCRIPTION:Speakers: Dominic Gaisbauer (Institute for Hadronic Structure 
 and Fundamental Symmetries\, TU Munich)\nPENeLOPE is a neutron-lifetime ex
 periment aiming for high precision by counting neutrons and decay protons.
  The proton detector consists of about 1250 Avalanche Photodiodes (APDs) w
 ith a total active area of 1225$~$cm$^2$. The detector and electronics wil
 l be operated on a high electrostatic potential of -30$~$kV\, in a magneti
 c field of 0.6$~$T and at a temperature of 77$~$K. The electronics include
  low-noise preamplifiers\, CR-RC shapers\, ADCs and FPGAs. Each FPGA reads
  out 96 12-bit SAR-ADCs with 1$~$MSps in parallel. We developed a firmware
  for the FPGAs including a self-triggering readout with continuous pedesta
 l calculation and configurable trigger threshold.\nThe data transmission a
 nd configuration is done via the Unified Communication Framework (UCF) we 
 developed at the Technical University of Munich. UCF is a unified network 
 protocol developed for FPGAs with built-in high-speed serial interfaces. I
 t provides up to 64 different communication channels via a single serial l
 ink. One channel is reserved for timing and trigger information\, the othe
 r channels can be used for slow-control interfaces and data transmission. 
 All channels are bidirectional and share network bandwidth according to as
 signed priority. The timing channel distributes messages with fixed latenc
 y and low jitter (about 20$~$ps) in one direction. From this point of view
  the protocol implementation is asymmetrical. The framework supports point
 -to-point connections and star-like 1:n topologies. The star-like topology
  can be used for front-ends with low data rates and time-distribution syst
 ems. In this topology\, the master broadcasts information according to ass
 igned priorities\, the slaves communicate in a time-sharing manner to the 
 master. \n\nThe project is supported by the Maier-Leibnitz-Laboratorium (G
 arching)\, the Deutsche Forschungsgemeinschaft and the Excellence Cluster 
 "Origin and structure of the Universe".\n\nhttps://indico.inp.nsk.su/event

SUMMARY:A custom readout electronics for the BESIII CGEM detector

DESCRIPTION:Speakers: Manuel Dionisio Da Rocha Rolo (INFN)\nThe design of 
 a custom front-end electronics for the readout of the new inner tracker of
  the BESIII experiment\, carried out at BEPCII in Beijing\,  is presented.
  For the upgrade of the inner detector\, planned for 2018\, a lightweight 
 tracker based on an innovative Gas Electron Multiplier (GEM) cylindrical d
 etector is now under development. The analogue readout of the CGEM enables
  the use of a charge centroid algorithm to improve the spatial resolution 
 to better than $130\\ \\mu$m while loosening the pitch strip to $650\\ \\m
 u$m\, which allows to reduce the total number of channels to about 10 000.
 \nThe channels are readout by 160 dedicated integrated 64-channel front-en
 d ASICs\, providing a time and charge measurement and featuring a fully-di
 gital output. \n\nThe energy measurement is extracted either from the time
 -over-threshold (ToT) or the 10-bit digitisation of the peak amplitude of 
 the signal.\nThe time of the event is generated by quad-buffered low-power
  TDCs\, allowing for rates up to 60 kHz per channel. The TDCs are based on
  analogue interpolation techniques and produce a time stamp (or two\, if w
 orking in ToT mode) of the event with a time resolution better than 100 ps
 . The front-end noise\, based on a CSA and a two-stage complex conjugated 
 pole shapers\, dominate the channel intrinsic time jitter\, which is less 
 than 5 ns r.m.s.. The time information of the hit can be used to reconstru
 ct the track path\, operating the detector as a small TPC and hence improv
 ing the position resolution when the distribution of the cloud\, due to la
 rge incident angle or magnetic field\, is very broad.\n\nEvent data is col
 lected by an off-detector motherboard\, where each GEM-ROC readout card ha
 ndles 4 ASIC carrier PCBs (512 channels). Configuration upload and data re
 adout between the off-detector electronics and the VME-based data collecto
 r cards are managed by bi-directional fibre optical links.\n\nThis talk wi
 ll cover the relevant design aspects of the detector electronics and the f
 ront-end ASIC for the CGEM readout\, and review the first silicon results 
 of the chip prototype.\n\nhttps://indico.inp.nsk.su/event/8/contributions/

DESCRIPTION:Speakers: Dmitri Kotchetkov (University of Hawaii at Manoa)\nT
 he imaging Time of Propagation (iTOP) detector is a new quartz Cherenkov r
 adiation detector to work at the Belle II experiment. The iTOP will identi
 fy\, with high precision\, charged hardons created in electron-positron co
 llisions at the SuperKEKB collider. With its timing resolution of less tha
 n 50 ps\, the iTOP will help searching for rare and previously unobserved 
 physics events while minimizing effects of SuperKEKB beam backgrounds on t
 he reconstructed data. The iTOP is built as a 16-module barrel detector pl
 aced at Belle II between the Central Drift Chamber and the Electromagnetic
  Calorimeter. In the iTOP\, Cherenkov photon signals are collected by micr
 ochannel plate photomultiplier tubes. Sixty four (four per each iTOP modul
 e) 128-channel electronic Subdetector Readout Modules (SRMs) sample the co
 llected photon signals\, digitize them\, read out the digitized data\, and
  then forward them to the Belle II back-end data acquisition system. Every
  SRM is composed of five boards. Four of those boards carry application-sp
 ecific integrated circuits (ASICs) that perform sampling and digitization\
 ; every board (the ASIC carrier board) has four 8-channel ASICs mounted on
  it. Sampling and digitization in each channel is done by a 16 x 32 (x 64)
  switched capacitor array using Wilkinson method. The ASIC carrier board\,
  in addition\, has a field-programmable gate array that reads out the digi
 tized data from the on-board ASICs. The fifth board of the SRM\, named as 
 Standard Control Readout Data (SCROD) board\, collects data from the four 
 ASIC carrier boards\, then buffer and forward them through an optical link
  to the back-end data acquisition system. The field-programmable gate arra
 y mounted on the SCROD board formats the data collected from the ASIC carr
 ier boards. The iTOP 8192-channel front-end electronic readout system was 
 built and integrated at Belle II. In situ commissioning of the system is u
 nderway. Performance studies of the calibration laser data acquisition\, w
 ith and without magnetic field of 1.5 T\, demonstrate that the iTOP channe
 ls collect data with the timing resolution of less than 50 ps.\n\nhttps://

DESCRIPTION:Speakers: Alexander Madorsky (University of Florida)\nTo accom
 modate high-luminosity LHC operation at 13 TeV collision energy\, the CMS 
 Endcap Muon Level-1 Trigger system had to be significantly modified. To pr
 ovide the best track reconstruction\, the trigger system must now import a
 ll available trigger primitives generated by Cathode Strip Chambers and by
  certain other subsystems\, such as Resistive Plate Chambers (RPC). In add
 ition to massive input bandwidth\, this also required significant increase
  in logic and memory resources. To satisfy these requirements\, a new Sect
 or Processor unit has been designed. It consists of three modules. The Cor
 e Logic module houses the large FPGA that contains the track-finding logic
  and multi-gigabit serial links for data exchange. The Optical module cont
 ains optical receivers and transmitters\; it communicates with the Core Lo
 gic module via a custom backplane section. The Pt Lookup Table (PTLUT) mod
 ule contains 1 GB of low-latency memory that is used to assign the final P
 t to reconstructed muon tracks. The µTCA architecture (adopted by CMS) wa
 s used for this design. The talk presents the details of the hardware and 
 firmware design of the production system based on Xilinx Virtex-7 FPGA fam
 ily. The next round of LHC and CMS upgrades starts in 2019\, followed by a
  major High-Luminosity (HL) LHC upgrade starting in 2024. In the course of
  these upgrades\, the new Gas Electron Multiplier (GEM) detector and more 
 RPC chambers will be added to the Endcap Muon system. In order to keep up 
 with all these changes\, a new Advanced Processor unit is being designed. 
 This device will be based on Xilinx UltraScale+ FPGAs. It will be able to 
 accommodate up to 100 serial links with bit rates of up to 25 Gb/s\, and p
 rovide up to 2.5 times more logic resources than the device used currently
 . The amount of PTLUT memory will be significantly increased to provide mo
 re flexibility for Pt assignment algorithm. The talk presents preliminary 
 details of the hardware design program.\n\nhttps://indico.inp.nsk.su/event

DESCRIPTION:Speakers: Serge Nagorny (Gran Sasso Science Institute)\nVery r
 ecently\, significant interest in crystal scintillators with KPtCl$_6$ str
 ucture has been renewed since they possess a high light yield\, linear res
 ponse at low energies\, and good energy resolution. Cs$_2$HfCl$_6$ (CHC)\,
  in particular\, a crystal belonging to the same structure group\, is one 
 of the most promising scintillator for gamma spectroscopy giving almost 54
 000 ph/MeV light yield and 3.3$\\%$ energy resolution at 662 keV. In addit
 ion\, the CHC crystal is the first scintillating material containing a hig
 h fraction of Hf in mass (of about 25$\\%$). This opens new opportunities 
 to search for a rare nuclear processes occurring in Hf isotopes applying t
 he "source = detector" experimental approach with high sensitivity. \n\nHe
 re we report the results of our investigation into a 3 cm$^{3}$ CHC crysta
 l as a promising detector of search for rare nuclear processes occurring i
 n Hf isotopes. For this reason\, the response of the crystal to irradiatio
 n by alpha particle was studied. The quenching factor for 5 MeV alpha part
 icles is 0.28\, showing that alpha particles produce almost a third of the
  light produced by gamma quanta. This crystal has also shown the ability t
 o discriminate between different types of radiation by applying pulse-shap
 e discrimination techniques. For example\, using the optimal filter method
  we determined the separation between signals with a Factor of Merit (FOM)
  = 6.08 for energy at 1 MeV. This means we can fully separate signals indu
 ced by alpha particles from those of gamma quanta. Similar results were ob
 tained using the mean time method. \n\nThe internal radioactive contaminat
 ion of our 3 cm$^3$ CHC was also studied. Using low-background measurement
 s with germanium gamma-spectrometer at Gran Sasso Underground Laboratory (
 Italy). The resulting analysis concluded that the crystal is free from nuc
 lides of U/Th natural decay chains\, only limits were set of their activit
 ies at the level of few mBq/kg were seen after 500 hours of measurements. 
 However\, the crystal contains artificial $^{137}$Cs nuclide (0.8 Bq/kg) a
 nd $^{134}$Cs at levels of tens of mBq/kg. Also observed nuclides produced
  by cosmic ray irradiation $^{132}$Cs and $^{181}$Hf with activities at th
 e level of tens of mBq/Kg. \n\nThe prospects of the CHC scintillating crys
 tal as a detector to search for rare nuclear decay of Hf isotopes is discu
 ssed.\n\nhttps://indico.inp.nsk.su/event/8/contributions/1654/

DESCRIPTION:Speakers: Stefano Terzo (IFAE)\nAn upgrade of the ATLAS experi
 ment for the High Luminosity phase of LHC is planned for 2024 and foresees
  the replacement of the present Inner Detector with a new Inner Tracker co
 mpletely made of silicon devices. \n\nDepleted Monolithic Active Pixel Sen
 sors (DMAPS) built with High Voltage CMOS (HV-CMOS) technology are investi
 gated as an option to cover large areas in the outermost layers of the pix
 el detector and are especially interesting for the development of monolith
 ic devices which will reduce the production costs and the material budget 
 with respect to the present hybrid assemblies. For this purpose the H35Dem
 o\, a large area HV-CMOS demonstrator chip\, was designed by KIT\, IFAE an
 d University of Liverpool\, and produced in AMS 350 nm CMOS technology. It
  consists of four pixel matrices and additional test structures. Two of th
 e matrices include both amplifiers and discriminator stages and are thus d
 esigned to be operated as monolithic detectors.\n\nIn these devices the si
 gnal is mainly produced by charge drift in a small depleted volume obtaine
 d increasing the bias voltage to the order of 100 V or more. Moreover\, th
 is technology allows to enclose the electronics in the same deep n-wells a
 lso used as collecting electrodes to enhance the radiation hardness of the
  chip.\n\nIn this contribution the characterisation of H35Demo chips and r
 esults of the very first test beam measurements of the monolithic matrices
  with high energetic pions at CERN SpS will be presented.\n\nhttps://indic

DESCRIPTION:Speakers: Klemens Lautenbach (JLU Giessen)\nThe Belle II exper
 iment\, at the future SuperKEKB collider in Tsukuba\, Japan\, features a d
 esign luminosity of $8\\cdot 10^{35}$ cm$^{-2}$s$^{-1}$\, which is a facto
 r of 40 larger than its predecessor KEKB. The pixel detector (PXD) with ab
 out 8 million pixels is based on the DEPFET technology and will improve th
 e vertex resolution in beam direction by a factor of 2. With an estimated 
 trigger rate of $30$ kHz\, the PXD is expected to generate a data rate of 
  20 GBytes/s\, which is about 10 times larger than the amount of data gene
 rated by all other Belle II subdetectors.\n\nDue to the large beam-related
  background\, the PXD needs a data acquisition system with high-bandwidth 
 data links and realtime background reduction by a factor of 10 as otherwis
 e the event builder will be saturated. To achieve this\, the Belle II pixe
 l DAQ uses an FPGA-based computing platform with high speed serial links i
 mplemented in the ATCA (Advanced Telecommunications Computing Architecture
 ) standard.\n\nThe architecture and performance of the data acquisition sy
 stem and data reduction of the PXD will be presented.\n\nIn April 2016 a p
 rototype PXD-DAQ system\, which was operated in a test beam campaign\, del
 ivered first data with the whole readout chain under realistic\, high rate
  conditions. Final results from the test beam will be presented.\n\nhttps:

DESCRIPTION:Speakers: Raffaele Giordano (University of Naples and INFN)\nS
 tatic RAM-based Field Programmable Gate Arrays (SRAM-based FPGAs) [1\, 2] 
 are widely adopted in Trigger and Data Acquisition (TDAQ) systems of High-
 Energy Physics (HEP) experiments for implementing fast logic due to their 
 re-configurability\, large real-time processing capabilities and embedded 
 high-speed serial IOs. However\, these devices are sensitive to radiation 
 effects such as single event upsets (SEUs) or multiple bit upsets (MBUs) i
 n the configuration memory\, which may alter the functionality of the impl
 emented circuit.  Therefore\, they  are normally employed only in off-dete
 ctor regions\,  where no radiation is present. Special families of SRAM-ba
 sed FPGAs (e.g. the Xilinx Virtex-5QV) have been designed for applications
  in radiation environments\, but their excessive cost (few 10k USD)\, with
  respect to their standard counterpart ($\\sim$ 500 USD)\, usually forbids
  their usage in many applications\, including HEP. Therefore\, there is a 
 strong interest in finding solutions for enabling the usage of standard SR
 AM-based FPGAs also on-detector.  Methods based on modular redundancy and 
 periodic refresh of the configuration\, i.e. configuration scrubbing\, are
  used in order to mitigate single event effects\, which become more signif
 icant as the technological scaling proceeds towards smaller feature sizes.
  In fact\, latest devices also include dedicated circuitry implementing er
 ror correcting codes for mitigating configuration errors. The expected bit
  configuration upset rate is valuable information for choosing which prote
 ction strategy\, or which mixture of strategies\, to adopt. \nTypically\, 
 test campaigns are carried out at dedicated irradiation facilities by mean
 s of heavy ions\, proton and neutron beams [3\,4\,5] and they permit to de
 termine the particle to bit error cross section. However\, a reliable pred
 iction of the upset rate\, and of radiation effects in general\, requires 
 the knowledge of the cross section as function of the particle species and
  their spectra and it depends on a detailed knowledge of the radiation flu
 xes. Often such information is not available with sufficient precision\, a
 nd when possible an in situ (or in flight for space applications) measurem
 ent of the upset rate is highly recommended. For instance\, experiments at
  the Large Hadron Collider have been monitoring SEUs in readout control FP
 GAs [6]\, experiments in space have been launched in order to measure sing
 le event effects rates and compare them to predictions based on cross sect
 ions [7]. Furthermore\, over the last decade\, FPGA vendors have been carr
 ying out experiments  aimed at measuring SEUs induced by atmospheric neutr
 ons in their devices [8].\n\nIn February 2016\, the SuperKEKB [9] $e^+e^-$
  high-luminosity ($8\\cdot10^{35} cm^{-2} s^{-1}$) collider of the KEK lab
 oratory (Tsukuba\, Japan) started being commissioned. A dedicated commissi
 oning detector\, named BEAST2\, has been being used to characterize beam b
 ackgrounds prior to the Belle2 detector roll into the beams and to provide
  tuning parameters for Monte Carlo simulations. BEAST2 consists of a fiber
 glass support structure and several subdetectors mounted onto it\,  includ
 ing time projection chambers (TPCs) and He-3 tubes. \n\nIn this work\, we 
 present direct measurements of radiation-induced soft-errors on a SRAM-bas
 ed FPGA device installed on the BEAST2 frame at a distance of $\\sim$ 1 m 
 from the beam interaction point. Our goal is to provide experimental resul
 ts of the expected FPGA configuration error rate and power consumption var
 iation at Belle2 and at other experiments operating in similar radiation c
 onditions.  For this study\, we designed a dedicated board hosting a Xilin
 x Kintex-7 325T device  without additional active components\, in such a w
 ay to be able to decouple FPGA failures from those of other devices. The b
 oard receives power and clock from dedicated remote generators installed i
 n a counting room. The configuration and read back are performed via a JTA
 G connection and they are managed by a dedicated single board computer . D
 uring the commissioning of the collider\, we periodically read back the FP
 GA configuration in order to detect errors and we logged the power consump
 tion on the different power domains of the device. Currents for both elect
 ron and positron rings spanned a range between 50 and 500 mA\, therefore p
 roviding data about the FPGA in different radiation conditions. Even if th
 e machine is not providing collisions yet\, as the beams are not focused t
 o the interaction point\, our results show a rate of 0.02 upsets/day avera
 ged over the whole commissioning time frame. BEAST2 subdetectors provided 
 valuable information about the radiation environment.\nThis work is part o

DESCRIPTION:Speakers: Bernard Dinkespiler (Centre de Physique des Particul
 es de Marseille)\nThe upgrade of the Large Hadron Collider (LHC) scheduled
  for shut-down period of 2018-2019\, referred to as Phase-I upgrade\, will
  increase the instantaneous luminosity to about three times the design val
 ue. Since the current ATLAS trigger system does not allow sufficient incre
 ase of the trigger rate\, an improvement of the trigger system is required
 . The Liquid Argon (LAr) Calorimeter read-out will therefore be modified t
 o use digital trigger signals with a higher spatial granularity in order t
 o improve the identification efficiencies of electrons\, photons\, tau\, j
 ets and missing energy\, at high background rejection rates at the Level-1
  trigger. The new trigger signals will be arranged in 34000 so-called Supe
 r Cells which achieves 5-10 times better granularity than the trigger towe
 rs currently used and allows an improved background rejection. The readout
  of the trigger signals will process the signal of the Super Cells at ever
 y LHC bunch-crossing at 12-bit precision and a frequency of 40 MHz.  The d
 ata will be transmitted to the back-end using a custom serializer and opti
 cal converter and 5.44 Gb/s optical links. In order to verify the full fun
 ctionality of the future Liquid Argon trigger system\, a demonstrator set-
 up has been installed on the ATLAS detector and is operated in parallel to
  the regular ATLAS data taking during the LHC Run-2. Noise level and linea
 rity on the energy measurement have been verified to be within our require
 ments. In addition\, we have collected data from 13 TeV proton collisions 
 during the LHC 2015 run\, and have observed real pulse from the detector t
 hrough the demonstrator system. The talk will give an overview of the Phas
 e-I Upgrade of the ATLAS Liquid Argon Calorimeter readout and present the 
 custom developed hardware including their role in real-time data processin
 g and fast data transfer. This contribution will also report on the perfor
 mance of the newly developed ASICs including their radiation tolerance and
  on the performance of the prototype boards in the demonstrator system bas
 ed on various measurements with the 13 TeV collision data. Results of the 
 high-speed link test with the prototypes of the final electronic boards wi
 ll be also reported.\n\nhttps://indico.inp.nsk.su/event/8/contributions/17
