Silicon photomultipliers (SiPMs) have become extensive used recently. They exceed photomultiplier tubes on quantum efficiency, size and resistance to the magnetic field. However, due to the features of the structure they have a greater value of dark noise rate, as well as they have additional sources of noise: cross-talk and after-pulsing. In addition, these parameters may have a temperature d ... More

This work was performed in the course of the development of a two-phase Cryogenic Avalanche Detector (CRAD) in Ar for dark matter search and low energy neutrino experiments. The detector included EL gap located directly above the liquid-gas interface, which was optically read out using cryogenic PMTs located on the perimeter of the gap and matrix of Geiger-mode APD (GAPD). The results of the measu ... More

The 20kt Liquid Scintillator (LS) JUNO detector is under construction by the International Collaboration in China with the primary goal to address the question of neutrino mass ordering (hierarchy). The main JUNO challenge is to achieve a record energy resolution, ~3% at 1MeV of energy released in the LS, which is required to perform the neutrino mass hierarchy determination. About 20’000 large ... More

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 Alte ... More

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 increase th ... More

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 techni ... More

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 an ...

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 reaction ... More

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 cro ... More

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 CM ... More
