Electroluminescence gas-filled detector with a build-in photocell

A Gas Proportional Scintillation Counter with krypton filling

“…The GPSC was vacuum pumped to pressures below 10 −5 mbar and, then, filled with krypton at a pressure of 1.1 bar. The gas was continuously purified by convection through St707 SAES getters [17], which were set to a stable temperature of about 150 • C.…”

“…These photosensors are fragile, bulky and power consuming devices. Alternative gaseous photosensors based on CsI-coated microstrip plates have been implemented [14][15][16], as well as multi-alkali photocathode based vacuum photocells [17]. However, solid-state large area avalanche photodiodes (LAAPD), developed in the last two decades, and the recently developed silicon-photomultipliers (SiPMs), pixelized avalanche photodiodes operating in Geiger mode, present an actual significant alternative to PMTs [18][19][20][21].…”
