The properties of thick GEM-like (TGEM) gaseous electron multipliers, operated at 1–740
Torr are presented. They are made of a G-10 plate, perforated with millimeter-scale diameter …

Thick GEM-like (THGEM) gaseous electron multipliers are made of standard printed-circuit
board perforated with sub-millimeter diameter holes, etched at their rims. Effective gas …

We report on the properties of thick GEM-like (THGEM) electron multipliers made of 0.4 mm
thick double-sided Cu-clad G-10 plates, perforated with a dense hexagonal array of 0.3 mm …

In the final decades of the last century, Ring Imaging Cherenkov (RICH) detectors
established themselves as the most robust and reliable particle identification (PID) …

We summarize the development of visible-sensitive gaseous photomultipliers, combining a
semitransparent bi-alkali photocathode with a state-of-the-art cascaded electron multiplier …

Gas Electron Multipliers with a reflective photocathode deposited on the surface of the first
multiplying element are very attractive devices for photon detection and imaging over large …

The sensitivity of many detection devices is established by the use photocathodes for the
conversion of incoming photons into photoelectrons. The choice of photocathode material is …

We have developed and tested several prototypes of GEM-like detectors with electrodes
coated with resistive layers or completely made of resistive materials. These detectors can …

Monte Carlo simulation is used to investigate photoelectron backscattering effects in the
emission from a CsI photocathode into CH 4 and Ar-CH 4 mixtures for incident …

We describe the preparation of a sealed gas-filled photomultiplier (GPMT) for the visible
spectral range and present the properties of the first prototypes. They consist of a 50 mm …
