An accurate knowledge of the colliding beam energies is essential for the current experiments with the KEDR detector at the VEPP-4M collider. Now the experimental activity is focused on the measurements of $\tau$~lepton mass and parameters of narrow resonances of the $\psi$-family in the c.m.energy range of 3.0--4.0~GeV. Two complementary approaches are used for the beam energy measurements....

Over the last few years, the nearly exact Boundary Element Method (neBEM) has been demonstrated to be a reasonably good candidate for solving electrostatic problems related to gas detectors. The recently developed Garfield-neBEM combination has been used here to simulate the performance of Micromegas detectors with realistic dimensions. The variation of electric field due to a change in the...

Silicon photo-multipliers, often called "SiPM", are semiconductor photon detectors built from a square matrix of avalanche photo-diodes on common silicon substrate. SiPM have been proposed for several different applications in High Energy Physics, in particular where a large detection granularity is needed. In this presentation the results of a radiation hardness test performed at the Frascati...

A sealed gaseous photomultiplier tube (PMT) with a CsI photocathode has been developed using a micropattern gas detector (MPGDs) made of Pyrex glass. By employing a microblasting technique completely different from that used in microchannel plate (MCP) production, we successfully produced the new hole-type MPGD using Pyrex glass (microblasted glass plate: MB-GP).

A few results on measurements of LYSO and LFS crystals with MAPD readout have been reported. These MAPDs were produced by Zecotek Co. and have 3x3 mm2 sensitive area. Due to the specific micro-wells structure such MAPDs have high pixel density up to 40000/mm2 that results in large dynamical range and linearity of MAPD response to intensive light pulses.

The goal of the NA62 experiment is to collect about 80 K+ -> pi+ nu anti-nu events with a S/B ratio of ~10:1. The branching ratio (BR) for this decay is ~10^-10 and can be predicted in the Standard Model with minimal theoretical uncertainties, making it a sensitive probe for new physics. Measurement of this BR is challenging because of the background from dominant channels. To reduce...
