“…It was demonstrated that CsI coated GEMs, capillary plates as well as THGEMs have high quantum efficiencies at cryogenic temperatures for the UV photons and thus can replace expensive photomultipliers usually used in cryogenic TPCs for the detection of the scintillation light. Recently the Novosibirsk group confirmed our results obtained with CsI coated GEMs [61] using a double phase noble liquid detector (see Fig. 23).…”

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.

“…Recently the Novosibirsk group confirmed our results obtained with CsI coated GEMs [29] and also confirmed that a THGEM is a very robust detector capable of operating stably at cryogenic temperatures up to 78 K [23]. This group also investigated the operation of the old version of the screen-printed resistive GEM (described in [10]) and fully confirmed our results obtained with this detector at room temperature [23].…”

We have developed and tested several new designs of GEM detectors with micropattern electrodes manufactured by microelectronic technology. In one design, the inner layer of the detector's electrode consists of thin metallic strips and the outer layer is made of a resistive grid manufactured by a screen printing technology. In other designs, the electrodes were made of metallic strips fed by HV via micro-resistors manufactured by a screen printing technology. Due to these features, the new detectors have several important advantages over conventional GEMs or ordinary thick GEMs. For example, the resistive grid (in the first design) and the screen printed resistors (in other designs) limited the current in case of discharges thus making these detectors intrinsically sparkprotected.We will here describe our tests with the photosensitive versions of these detectors (coated with CsI layers) and the efforts of implementing them in several applications. In particular, we will focus on our activity towards the ALICE RICH detector upgrade and on tests of simplified prototypes of cryogenic dark matter detectors.

“…A triple-GEM structure with a CsI photocathode deposited on the bottom surface of the first GEM was tested in double-phase argon at 84 K and P = 0.7 bar [340,302]. Primary scintillation from 60 keV γ-rays was detected at a gain of 1.4·10 3 , however with surprisingly low efficiency (about 2 photoelectrons at the entrance of the first GEM).…”

We review the current status of liquid noble gas radiation detectors with energy threshold in the keV range, which are of interest for direct dark matter searches, measurement of coherent neutrino scattering and other low energy particle physics experiments. Emphasis is given to the operation principles and the most important instrumentation aspects of these detectors, principally of those operated in the double-phase mode. Recent technological advances and relevant developments in photon detection and charge readout are discussed in the context of their applicability to those experiments.
