A nine-channel photodetector unit with micropixel avalanche photodiodes (MAPD) and precision thermostabilization based on the compact Peltier element is designed and constructed. MAPD-3N with superhigh pixel density 15000 per square mm and area 3×3 mm manufactured by the Zecotek Company were used.

The Tile Calorimeter (TileCal) is the hadronic calorimeter of ATLAS covering the central region of the ATLAS experiment. TileCal will undergo a major replacement of its on- and off-detector electronics for the high luminosity programme of the LHC in 2024.
The calorimeter signals will be digitized and sent directly to the off-detector electronics, where the signals are reconstructed and...

As an alternative of the crystal choice for the Mu2e
calorimeter, we have tested single crystals of pure CsI in combination
with large area MPPC from Hamamatsu. The MPPC under consideration,
consisting of an array of 16 3$\times$ 3 mm$^2$ cells, 50 $\mu$m pixels,
grants an active area of 12$\times$12 mm$^2$ and has
an improved PDE reaching $\sim$ 40 \%
down to 250 nm thus well...

The muon anomaly (g-2)/2 has been measured to 0.54 parts per million by
E821 experiment at Brookhaven Lab, and at present there is a 3 to
4-standard deviation difference between the SM and experimental values.
A new muon (g - 2) experiment, E989, is being prepared at Fermilab that
will improve the experimental error by a factor of four to clarify this
difference.
A central component to...

A sampling calorimeter using cerium fluoride scintillating crystals as active material, interleaved with absorber plates made of tungsten,and read out by wavelength-shifting fibers has been studied as a calorimeter option for detectors at the upgraded LHC collider at CERN. A prototype has been exposed to high-energy electron beams at the CERN SPS H4 beam line, as well as to lower-energy beams...

IMCP is an R&D project aimed at the exploitation of secondary emission of electrons from the surface of micro-channel plates (MCP) for fast timing of showers in high rate environments. The usage of MCPs in "ionisation" mode has long been proposed and is used extensively in ion time-of-flight mass spectrometers. What has not been investigated in depth is their use to detect the ionizing...

BELLE II is the upgrade of BELLE by 40 times luminosity, investigating the CP-violation effects. In order to cope with the extremely high luminosity at Belle II, utilizing fast pure CsI scintillation crystals at end cup of ECL has been proposed. Silicon avalanche photodiodes (APD) are considered as a candidate of photosensitive elements to get the acceptable level of the electronic noises. In...

This paper reports charged hadron induced radiation damage in crystal scintillators using 800 MeV proton beam at the WNR facility of LANSCE. A 20 cm long LYSO crystal, a 14 cm long CeF3 crystal and four liquid scintillator based sealed quartz capillaries were irradiated to the level of 1014 p/cm2 by 800 MeV protons in the WNR facility of LANSCE. The results show that the emission weighted...

A compact high-granularity electromagnetic calorimeter prototype has been built to perform generic R&D for an upgrade proposal of a forward calorimeter (FoCal) in the ALICE experiment, which should have very good gamma/π0 discrimination capabilities. The prototype is a Si/W sampling calorimeter using CMOS sensors of the MIMOSA type with a pixel pitch of 30 micron and binary readout with a...

We present a study of micro-channel plate photomultipliers (MCP-PMT) as the active element of an electromagnetic shower maximum (SM) detector. Results for Photek 240 and Photonis XP85011 MCP-PMT devices were obtained at the Fermilab Test Beam Facility. The time resolutions obtained for this new type of SM detector is at the level of ~12 ps for Photek 240 and ~27 ps for Photonis XP85011 with...

CMD-3 is a general purpose detector designed to study $e^+e^-$ annihilation in hadrons in the wide energy range, $E_{c.m.s}=0.3\div2$~GeV. Since 2010 CMD-3 collected data at the $e^+e^-$ collider VEPP-2000 in the Budker Institute of Nuclear Physics. VEPP-2000 collider with $10^{32}cm^{-2}s^{-1}$ luminosity is the only present collider which covers its energy range. The calorimetry at the...

Neutrino cross section measurements are an essential requirement for
the next generation of neutrino oscillation experiments and they are
presently limited by uncertainties on neutrino fluxes. In [1] we propose
to instrument a neutrino decay tunnel to detect large angle
positrons and tag the three-body semileptonic $K^+ \to e^+ \pi^0 \nu_e$
decays. In such a facility the absolute...

The liquid xenon calorimeter of the MEG experiment at PSI is designed to have a percent-level resolution at a photon energy of $52.8~$MeV. To measure its performance, stability and uniformity it is mandatory to have a calibration source as close as possible to this energy.
The charge exchange reaction of negative pions at rest on protons produces both mono-energetic 129~MeV photons and a...

The Ce-SOX experiment is being built to clarify neutrino anomalies by observing possible short distance neutrino oscillations. For this purpose, a 100 kCi 144Ce-144Pr antineutrino generator will be placed under the BOREXINO detector at the Laboratori Nazionali del Gran Sasso in Italy. Thanks to its large size and very low background, BOREXINO is an ideal detector to discover or refute eV-scale...
