Two-phase argon and xenon avalanche detectors based on Gas Electron Multipliers
A. Bondar, A. Buzulutskov, A. Grebenuk +3
We study the performance of two-phase avalanche detectors based on Gas Electron Multipliers (GEMs) and operated in an electron-avalanching mode in Ar and Xe. Emission, gain, energy…
Recent results on the properties of two-phase argon avalanche detectors
A. Bondar, A. Buzulutskov, A. Grebenuk +2
The characteristic properties of two-phase Ar avalanche detectors, including those obtained with CsI photocathode, are further studied. Such detectors are relevant in the field of…
GEM operation in helium and neon at low temperatures
A. Buzulutskov, J. Dodd, R. Galea +9
We study the performance of Gas Electron Multipliers (GEMs) in gaseous He, Ne and Ne+H2 at temperatures in the range of 2.6-293 K. In He, at temperatures between 62 and 293 K, the…
First results of the two-phase argon avalanche detector performance with CsI photocathode
A. Bondar, A. Buzulutskov, A. Grebenuk +3
The performance of a two-phase Ar avalanche detector with CsI photocathode was studied, with regard to potential application in coherent neutrino-nucleus scattering and dark matter…
A two-phase argon avalanche detector operated in a single electron counting mode
A. Bondar, A. Buzulutskov, A. Grebenuk +6
The performance of a two-phase Ar avalanche detector in a single electron counting mode was studied, with regard to potential application in coherent neutrino-nucleus scattering an…
Thick GEM versus thin GEM in two-phase argon avalanche detectors
A. Bondar, A. Buzulutskov, A. Grebenuk +3
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 sc…
Gas Purity effect on GEM Performance in He and Ne at Low Temperatures
R. Galea, J. Dodd, Y. Ju +6
The performance of Gas Electron Multipliers (GEMs) in gaseous He, Ne, He+H2 and Ne+H2 was studied at temperatures in the range of 3-293 K. This paper reports on previously publishe…
Electron emission properties of two-phase argon and argon-nitrogen avalanche detectors
A. Bondar, A. Buzulutskov, A. Grebenuk +2
Electron emission properties of two-phase Ar avalanche detectors are studied. The detectors investigated comprised a liquid Ar or Ar+N2 layer followed by a multi-GEM multiplier ope…
