Abstract: Identification of high momentum hadrons at the future EIC is crucial, gaseous RICH detectors are therefore viable option. Compact collider setups impose to construct RICHes with small radiator length, hence significantly limiting the number of detected photons. More photons can be detected in the far UV region, using a windowless RICH approach. QE of CsI degrades under strong irradiation and air contamination. Nanodiamond based photocathodes (PCs) are being developed as an alternative to CsI. Recent development of layers of hydrogenated nanodiamond powders as an alternative photosensitive material and their performance, when coupled to the THick Gaseous Electron Multipliers (THGEM)-based detectors, are the objects of an ongoing R&D. We report about the initial phase of our studies.

Development of photocathodes for gaseous counters: From UV to visible
TL;DR: In this article, an overview of the present status and prospect of implementing photon converters in gaseous counters is presented. But, because of their chemical reactivity with most materials and fragility to secondary electron emission and ion bombardment, compounds sensitive to long wavelength photons very easily experience a severe reduction of their lifetime and deterioration of performance.
