The magnetic characteristics of photomultiplier tube R5610A-01 are studied in this paper. The experimental data shows that the gain of R5610A-01 loses about 53% when the magnetic field is 3G along its +X axis. A cylinder of one-layer permalloy strip is able to reduce the effect of 3G magnetic field on the PMTs gain to less than 1%.

A BGO electromagnetic calorimeter (ECAL) is built for the DArk Matter Particle Explorer (DAMPE) mission. The effect of temperature on the BGO ECAL was investigated with a thermal vacuum experiment. The light output of a BGO crystal depends on tempera
ture significantly. The temperature coefficient of each BGO crystal bar has been calibrated, and a correction method is also presented in this paper.
The Heavy Photon Search experiment (HPS) is searching for a new gauge boson, the so-called heavy photon. Through its kinetic mixing with the Standard Model photon, this particle could decay into an electron-positron pair. It would then be detectable
as a narrow peak in the invariant mass spectrum of such pairs, or, depending on its lifetime, by a decay downstream of the production target. The HPS experiment is installed in Hall-B of Jefferson Lab. This article presents the design and performance of one of the two detectors of the experiment, the electromagnetic calorimeter, during the runs performed in 2015-2016. The calorimeters main purpose is to provide a fast trigger and reduce the copious background from electromagnetic processes through matching with a tracking detector. The detector is a homogeneous calorimeter, made of 442 lead-tungstate (PbWO4) scintillating crystals, each read out by an avalanche photodiode coupled to a custom trans-impedance amplifier.
The DArk Matter Particle Explorer (DAMPE) is a space-borne high energy cosmic-ray and $gamma$-ray detector which operates smoothly since the launch on December 17, 2015. The bismuth germanium oxide (BGO) calorimeter is one of the key sub-detectors of
DAMPE used for energy measurement and electron proton identification. For events with total energy deposit higher than decades of TeV, the readouts of PMTs coupled on the BGO crystals would become saturated, which results in an underestimation of the energy measurement. Based on detailed simulations, we develop a correction method for the saturation effect according to the shower development topologies and energies measured by neighbouring BGO crystals. The verification with simulated and on-orbit events shows that this method can well reconstruct the energy deposit in the saturated BGO crystal.
This paper presents mechanical R&D for the CALICE Silicon-tungsten electromagnetic calorimeter. After the physics ECAL prototype, tested in 2006 (DESY-CERN), 2007 (CERN), 2008 (FNAL) and before the design of different modules 0 (barrel and endcap) fo
r a final detector, a technological ECAL prototype, called the EUDET module, is under design in order to have a close to full scale technological solution which could be used for the final detector, taking into account future industrialisation of production.
The CALICE prototype for a Si/W electromagnetic calorimeter has been tested in large scale test beams. Several million events with electrons and hadrons of different energies and impact angles have been recorded. The energy resolution has been measur
ed to be (16.6 +- 0.1)%/sqrt(E(GeV)) for the stochastic and (1.1 +- 0.1)% for the constant term with a linearity within the 1% level. The next step will be the construction of a large scale prototype which will take realistic experimental costraints into account. This module will naturally benefit from the experience gained with the first prototype.
