The number of read-out channels in modern experiments can reach very high values. This requires the use of electronics at a low cost per channel. Such result could be achieved through the use of widely available commercial electronic components.
In this work we present newly developed TDC (Time-to-Digital Converter) block in the VME-32 standard. The 32-channel block is based on a single FPGA...

In MEPhI, the URAN array, consisting of detectors based on scintillator with natural boron, to study neutron EAS has been created. The array consists of 72 en-detectors, in which the recording material is an inorganic scintillator which represents a silicon plate with an alloy granules of mixture of scintillator ZnS (Ag) and B2O3. Thermal neutrons are recorded due to the isotope 10B (main...

The BESIII experiment at the BEPCII electron positron collider at IHEP (Beijing) is collecting data in the charm-$\tau$ mass region. Electron positron collisions are a very well suited environment for the study of initial state radiation (ISR). However, the photons from ISR are strongly peaked towards small polar angles and are currently detected with limited efficiency.
In order to...

The large-scale coordinate-tracking detector TREK for registration of inclined EAS is being developed in MEPhI. The use of large drift chambers (4000x508x112 mm$^3$) developed in IHEP for experiments at the neutrino channel of U-70 accelerator will allow to create a unique large-scale detector of 270 m$^2$ area for registration of multi-particle events at large zenith angles generated by...

The time-of-flight system now is installed at the CMD-3 detector of the VEPP-2000 electron-positron collider at the Budker Institute of Nuclear Physics. It is based on the strips of organic scintillator with shifter fibers readout and silicon photomultiplier (SiPM) photodetectors. The new electronics for TOF subsystem is designed at the Budker Institute of Nuclear Physics. The main feature of...

One of the goals of the Cryogenic Magnetic Detector at Budker Institute of Nuclear Physics SB RAS (Novosibirsk, Russia) is a study of hadron production in electron-positron collisions near threshold. The neutron-antineutron pair production events can be detected only by the calorimeters. In the barrel calorimeter the antineutron annihilation typically occurs about 5 ns or later after the beams...

Since 2010 the electromagnetic endcap calorimeter based on BGO crystals is taking part in experiments as one of the system of CMD-3 detector. The spacial resolution is one of crucial parameters of the calorimeter. The inaccurate knowledge of real calorimeter position can limit the resolution.
In this work the alignment of the center of the calorimeter with respect to the tracking system of...

The muon g-2/EDM experiment at J-PARC aims to measure the muon’s anomalous magnetic moment and electric dipole moment with high precision by utilizing an ultra-cold muon beam. Current muon g-2 discrepancy between Standard Model prediction and average experimental value is about 3 standard deviation. This experiment requires a development of the muon LINAC to accelerate thermal muons to 300...

The Mu2e experiment aims to measure the charged-lepton flavour violating (CLFV) neutrino-less conversion of a negative muon into an electron in the field of a nucleus. The conversion process results in a monochromatic electron with an energy slightly below the muon rest mass (104.97 MeV). Goal of the experiment is to improve of four orders of magnitude the previous measurement with similar...

The entire tracking system of the ATLAS experiment will be replaced during the LHC Phase II shutdown (foreseen to take place around 2025) by an all-silicon detector called the “ITk” (Inner Tracker).
The innermost portion of ITk will consist of a pixel detector with five layers in the barrel region and and ring-shaped supports in the endcap regions. It will be instrumented with new sensor...

The era of High Luminosity LHC (HL-LHC) will pose unprecedented challenges for detector design and operation. The planned luminosity of the upgraded machine is $5*10^{34}cm^{-2}s^{-1}$, possibly reaching an integrated luminosity of 3000fb$^{-1}$ by the end of 2037. CMS Tracker detector will have to be replaced in order to fully exploit demanding operating conditions and delivered luminosity....

Since 2010 the CMD-3 detector has been collecting data at the e+e- collider VEPP-2000 in the Budker Institute of Nuclear Physics. One of the main goals of experiments with CMD-3 detector is the precise measurement of the cross sections of the e+e- anihilation into hadrons. One of the main source of systematic uncertainty is determination of polar angles of tracks. Z-chamber is used for the...
