“…This energy loss, is higher than the energy loss of close-to-minimum-ionizing muons, thus the signal amplitude after calibration is given by an electron-to-muon scale factor C e − ⇔µ − of 0.82. This experimentally measured factor is consistent with predictions by GEANT4 simulations of the laboratory setup discussed in [12], which yields a most probable energy loss of 90 Sr electrons of approximately 980 keV and of relativistic muons of approximately 805 keV. This scale factor is used throughout the analysis of the T3B data.…”

The goal of the T3B experiment is the measurement of the time structure of hadronic showers with nanosecond precision and high spatial resolution together with the CALICE hadron calorimeter prototypes, with a focus on the use of tungsten as absorber medium. The detector consists of a strip of 15 scintillator cells individually read out by silicon photomultipliers (SiPMs) and fast oscilloscopes with a PC-controlled data acquisition system. The data reconstruction uses an iterative subtraction technique which provides a determination of the arrival time of each photon on the light sensor with sub-nanosecond precision. The calibration is based on single photonequivalent dark pulses constantly recorded during data taking, automatically eliminating the temperature dependence of the SiPM gain. In addition, a statistical correction for SiPM afterpulsing is demonstrated. To provide the tools for a comparison of T3B data with GEANT4 simulations, a digitization routine, which accounts for the detector response to energy deposits in the detector, has been implemented.

Abstract：Circular Electron Position Collider (CEPC) is proposed as a Higgs or Z factory. This work introduces the R&D progress of CEPC hadronic calorimeter (HCAL) based on particle flow algorithm (PFA). Two options include digital (DHCAL) and analog (AHCAL) readout are considered. The RPC DHCAL prototype made by CALICE, we have analysis some beam test data. The GEM detector for DHCAL is under developed. Detector cell of AHCAL have been detail studied, including material, light output and uniformity. The construction of a 51cm x51cm 35 layers AHCAL prototype has been started. Our R&D work would surely be more and more integrated into international PFA calorimeter activities.

“…To ensure detection of only electrons that fully penetrate the tile under study, a small (5 mm) 3 trigger scintillator with SiPM readout which moves together with the source is located at the bottom of the setup. These electrons deposit on average about 15% more energy than a minimum-ionizing particle [4] that penetrates the tile. For all studies, we use Hamamatsu MPPCs 1 , with different active area and pixels size depending on the application.…”

Abstract-The recent availability of blue sensitive silicon photomultipliers allows the direct readout of blue emitting plastic scintillator tiles without the use of a wavelength shifting fiber. Such directly read out tiles, without light guides, are attractive for the use in highly granular calorimeters that use large numbers of individual cells and in other applications where very compact designs are needed. However, the total signal amplitude and the uniformity of the response can be problematic in such cases. We have developed a scanning setup to investigate the response of scintillator tiles with SiPM readout in detail. It was used to develop optimized scintillator tile geometries for highly granular hadronic calorimetry at future colliders and to investigate the feasibility of a SiPM readout for the trigger of the ATLAS ALFA luminosity detectors. We report on results obtained with specialized scintillator tile geometries, discuss first results obtained with directly coupled SiPM readout of the ATLAS ALFA trigger tiles and introduce the application of fiberless readout in an experiment to study the time structure of hadronic showers.
