Investigation of gas discharge impulse image intensifiers

The gas discharge impulse image intensifiers (GDIII) operated in the streamer mode are studied in this work. The GDIII has a resolution of 5–15 lines/cm and light amplification up to ∼1010. The possibility to design a single-electron GDIII for RICH-detectors is considered. For this purpose the emission of photoelectrons in He, Ne, Ar, Xe, CO2, iC4H10 and their mixtures in the 50–760 Torr pressure range have been investigated. The best working gas for the GDIII is Ne+(∼0.1%)iC4H10 mixture having an electron output factor up to 0.45.
