The CMS ECAL is a hermetic, fine grained and homogeneous calorimeter containing 75848 lead-tungstate (PbWO₄) crystals, located inside the CMS superconducting solenoidal magnet. The scintillation light is detected by avalanche photodiodes (APDs) in the barrel section and by vacuum phototriodes (VPTs) in the two endcap sections. A silicon/lead pre-shower detector is installed in front of the...

The Tile Calorimeter (TileCal) is the central section of the ATLAS hadronic calorimeter at the Large Hadron Collider, a key detector for the measurements of hadrons, jets tau leptons and missing transverse energy. Scintillation light produced in the tiles is transmitted by wavelength shifting fibers to photomultiplier tubes (PMTs).

We have uniformly irradiated liquid argon ionization chambers with betas from high-activity Strontium-90 sources.
The radiation environment is similar to that in the liquid argon calorimeters which are part of the ATLAS detector installed at CERN's Large Hadron Collider (LHC). We measured the resulting ionization current over a wide range of applied potential for two different source...

The purpose of the MEG experiment is to look for a lepton flavor violating μ→eγ decay with an unprecedented sensitivity, and we set an upper limit of the branching ratio for this decay, 5.7×10⁻¹³ at 90% C.L. in 2013 which is twenty times more stringent limit than the previous experiment, MEGA. Since the sensitivity improvement of the MEG experiment was limited by the accidental background, we...

Scintillators with fast decay time, such as the barium fluoride fast component (220 nm) or liquid xenon (165 nm) pose a difficult problem for photodetectors. This motivates the development by a Caltech/JPL/RMD collaboration of large area (~10×10 mm) avalanche photodiodes using superlattice doping. These devices have high quantum efficiency and extended UV response and excellent timing...

Development of detector materials takes place both due to the search of new scintillation crystal, and by improvement of growing technology for already known crystals.
Basically scintillation crystals are grown by traditional techniques under high temperature gradient conditions. In most cases, the temperature gradients nearly growth interface are in the range 40-200 K/cm. In such conditions...

At the future Belle II experiment the inner DEPFET (DEPleted Field Effect Transistor) pixel detector will consist of ~8 million channels. Because of its small distance to the interaction region and the high luminosity in Belle II, for a trigger rate of ~30 kHz with an estimated occupancy of ~3% a data rate of ~22 GB/s is expected. Due to the high data rate a reduction factor higher than 30 is...

The ILC hadron calorimeter is supposed to consist from nearly 10 000 000 tiles 30x30x3 mm. The configuration of tile readout without WLS-fiber is studied and is being optimized in terms of response uniformity. With a SiPM positioned in the center of tile and hole milled in front of a SiPM uniformity of 8% has been achieved. This enables sandwich technology in detector plane construction.
