Thick GEM versus thin GEM in two-phase argon avalanche detectors

The performance of thick GEMs (THGEMs) was compared to that of thin GEMs in two-phase Ar avalanche detectors, in view of their potential application in coherent neutrino-nucleus scattering, dark-matter search and in other rare-event experiments. The detectors comprised a 1 cm thick liquid-Ar layer followed by either a double-THGEM or a triple-GEM multiplier, operated in the saturated vapor abov...

Development and Test of Large Size GEM Detectors

We discuss the main operating features of GEM detectors, optimized for use as trackers in a high radiation environment. The construction, tests and performances of large prototypes for the COMPASS experiment are also described, as well as the results of an exposure to very high intensity beams. I. GEM OPERATION AND PERFORMANCES The basic element in GEM detectors is a thin polymer foil, metal-cl...

Development of a large area gas photomultiplier with GEM/μPIC

We are developing a new photon detector with micro pattern gaseous detectors. A semitransparent CsI photocathode is combined with 10cm×10cm GEM/μPIC for the first prototype which is aimed for the large liquid Xe detectors. Using Ar+C2H6 (10%) gas, we achieved the gas gain of 10 which is enough to detect single photoelectron. We, then, irradiated UV photons from a newly developed solid scintilla...

Homogeneous Large Area CVD-Diamond Detectors for Tracking and ToF

In the last year, we continued with the development of large-area diamond sensors grown at the University of Augsburg by chemical vapour deposition (CVD) on wafer scale Ir/YSZ/Si(001) substrates. Early results of diamondon-iridium (DoI) sensors [1] were indicating significant defect densities within the detector bulk, which led to reduced charge collection efficiencies CCE = QColl/QGen= 40% (wi...

Development of GaN photocathodes for UV detectors

We have made substantial progress in the development of GaN photocathodes, including crystalline and polycrystalline GaN and InGaN coatings grown by chemical vapor deposition or molecular beam epitaxy on sapphire substrates. GaN and InGaN photocathodes have been developed with efficiencies up to 70% and cutoffs at 380 nm with low out of band response, and high stability and longevity. Samples h...
