(INFN, Pisa ; Siena U.) et al.
We report on the results of an extensive R&D; program aimed at the evaluation of Thick-Gas Electron Multipliers (THGEM) as potential active elements for Digital Hadron Calorimetry (DHCAL). Results are presented on efficiency, pad multiplicity and discharge probability of a 10x10 cm2 prototype detector with 1 cm2 readout pads. [...]

Further evaluation of a THGEM UV-photon detector for RICH - comparison with MWPC / Peskov, V. (Weizmann Inst. ; CERN) ; Cortesi, M. (Weizmann Inst.) ; Chechik, R. (Weizmann Inst.) ; Breskin, A. (Weizmann Inst.)
The operation of single-, double- and triple-THGEM UV-detectors with reflective CsI photocathodes (CsI-THGEM) in Ne/CH4 and Ne/CF4 mixtures was investigated in view of their potential applications in RICH. The studies were carried out with UV, x-rays and {\beta}-electrons and focused on the maximum achievable gain, discharge probability, cathode excitation effects and long-term gain stability. [...]

Towards THGEM UV-photon detectors for RICH: on single-photon detection efficiency in Ne/CH$_{4} and Ne/CF$_4$ / Azevedo, C.D.R. (Aveiro U. ; Weizmann Inst.) ; Cortesi, M.

(Coimbra U. ; Weizmann Inst.) ; Veloso, J.F.C.A. (Aveiro U.) ; dos Santos, J.M.F. (Coimbra U.)
The article deals with the detection efficiency of UV-photon detectors consisting of Thick Gas Electron Multipliers (THGEM) coated with CsI photocathode, operated in atmospheric Ne/CH4 and Ne/CF4 mixtures. We report on the photoelectron extraction efficiency from the photocathode into these gas mixtures, and on the photoelectron collection efficiency into the THGEM holes. [...]

THGEM operation in Ne and Ne/CH4 / Cortesi, M (Weizmann Inst.) ; Peskov, V (Weizmann Inst. ; CERN ; St. Etienne, Ecole des Mines) ; Bartesaghi, G (Weizmann Inst. ; Milan U. ; INFN, Milan) ; Miyamoto, J (Weizmann Inst.) ; Cohen, S (Weizmann Inst.) ; Chechik, R (Weizmann Inst.) ; Maia, J M (Coimbra U. ; Beira Interior U.) ; Santos, J M F dos (Coimbra U.) ; Gambarini, G (Milan U. ; INFN, Milan) ; Dangendorf, V (Berlin, Phys. Tech. Bund.) et al.
The operation of Thick Gaseous Electron Multipliers (THGEM) in Ne and Ne/CH4 mixtures, features high multiplication factors at relatively low operation potentials, in both single- and double-THGEM configurations. We present some systematic data measured with UV-photons and soft x-rays, in various Ne mixtures. [...]

2-D imaging with cascaded GEM/MHSP multipliers / Maia, J M ; Mörmann, D ; Breskin, Amos ; Chechik, R ; Veloso, J F C A ; Dos Santos, J M F
The imaging properties of cascaded-GEM (Gas Electron Multiplier) and cascaded-GEM/MHSP (Micro-Hole and Strip Plate) gaseous electron multipliers, equipped with 2-D Wedge & Strip (W&S;) readout electrodes, are presented. The W&S; electrode was capacitively coupled to the electron multiplier through a resistive electrode, to adapt the charge-cloud size to the 1.6 mm readout pitch. [...]

Review of the Development of Caesium Iodide Photocathodes for Application to Large RICH Detectors / ALICE Collaboration
CsI photocathodes were studied in order to evaluate their potential use as large photo converters in RICH detectors for the PID system at ALICE (LHC in heavy-ion collider mode). It has been demonstrated that a quantum efficiency comparable to the reference value obtained on small samples can be obtiained on CsI layers evaporated on large pad electrodes operated in a MWPC at atmospheric pressure.
