Advances in the technologies associated with position sensitive gaseous detectors especially featuring CsI as reflective photoconverters will be reviewed. These photodetectors represent the most effective solution for what concerns cost and performance in the case of large area Cherenkov imaging applications in relatively low rate (or low occupancy) high energy physics and astrophysics experiments. Moreover, they are the only choice when the Cherenkov detector is embedded in a magnetic field. Recently proposed single-photon MPGDs (Micro-Pattern-Gaseous Detectors) will be also discussed in view of the successful efforts so far made to extend their sensitivity to visible light. With some modifications, photosensitive gaseous detectors can also be used in the imaging of X-rays and particles.

Abstract-We describe here various detector designs: GEM-type, MICROMEGAS-type, as well as cascaded detectors made of a resistive mesh manufactured from a resistive Kapton foil, (20 m thick, surface resistivity a few M cm 2 ) by a laser drilling technique. As in any other micro-pattern detector, the maximum achievable gas gain of these detectors is restricted by the Raether limit; however, the resistive mesh makes them and the front end electronics fully spark protected. This approach may function as an alternative/or complementary component of the ongoing efforts in developing MICROMEGAS and GEMs with resistive anode readout plates and can be especially beneficial in micro-pattern detectors combined with a micro-pixel-type integrated front end electronics.

“…Somewhat higher QE values, of ~4-6% at 400nm, were reported in [69] with double capillary-plate detectors with CsSb and bialkali PCs operated in 1atm Ar/5%CH 4 ; lower gains, of 1000, resulted from an enhanced ion feedback due the higher QE [12]. In later studies, these authors focused on gas optimization for capillary plates [70]; He-based mixtures (1 atm He/5%isobutane or He/5%Xe) were investigated, with ethylferrocene vapors additives that reduced ioninduced electron emission. Gains above 10 3 were reached with a single capillary plates plus a parallelplate multiplier.…”

We review latest progress in gaseous photomultipliers (GPM) combining solid photocathodes and various types of novel electron multipliers. Cascaded gaseous electron multipliers (GEM) coated with CsI photocathodes can efficiently replace UVsensitive wire chambers for single-photon recording in Cherenkov and other detectors. Other hole-multipliers with patterned electrodes (Micro-Hole and Strip Plates) and improved ion-blocking properties are discussed; these permit reducing considerably photon-and ion-induced secondary effects. Photon detectors with other electron-multiplier techniques are briefly described, among them GPMs based on Micromegas, capillary-plates, Thick-GEMs and resistive Thick GEMs. The two latter techniques, robust and economically produced, are particularly suited for large-area GPM applications, e.g. in RICH. Cascaded hole-multipliers with very high ion-blocking performance permitted the development and the first demonstration of DC-operated visible-sensitive gaseous photomultipliers with bialkali photocathodes and single-photon sensitivity. Recent progress is described in GPMs operated at cryogenic temperatures for rare-event noble-liquid detectors and medical imaging.
