Bubble-assisted Liquid Hole Multipliers in LXe and LAr: towards "local dual-phase TPCs"
E. Erdal, L. Arazi, A. Breskin +5
The bubble-assisted Liquid Hole Multiplier (LHM) is a novel concept for the combined detection of ionization electrons and scintillation photons in noble-liquid time projection cha…
First results of Resistive-Plate Well (RPWELL) detector operation at 163 K
A. Roy, M. Morales, I. Israelashvili +7
We present for the first time, discharge-free operation at cryogenic conditions of a Resistive-Plate WELL (RPWELL) detector. It is a single-sided Thick Gaseous Electron Multiplier…
Recent Advances in Bubble-Assisted Liquid Hole Multipliers in Liquid Xenon
E. Erdal, L. Arazi, A. Tesi +4
We report on recent advances in the operation of bubble-assisted Liquid Hole Multipliers (LHM). By confining a vapor bubble under or adjacent to a perforated electrode immersed in…
Progress with Xenon Liquid Hole Multipliers
Lior Arazi, Eran Erdal, Yevgeniya Korotinsky +5
The bubble-assisted Liquid Hole Multiplier (LHM) is a recently-proposed concept for the combined detection of ionization electrons and primary scintillation photons in noble-liquid…
Fast-neutron and gamma-ray imaging with a capillary liquid xenon converter coupled to a gaseous photomultiplier
I. Israelashvili, A. E. C. Coimbra, D. Vartsky +4
Gamma-ray and fast-neutron imaging was performed with a novel liquid xenon (LXe) scintillation detector read out by a Gaseous Photomultiplier (GPM). The 100 mm diameter detector pr…
Observation of electron excitation into silicon conduction band by slow-ion surface neutralization
S. Shchemelinin, A. Breskin
Bare reverse biased silicon photodiodes were exposed to 3eV He+, Ne+, Ar+, N2+, N+ and H2O+ ions. In all cases an increase of the reverse current through the diode was observed. Th…
First demonstration of VUV-photon detection in liquid xenon with THGEM and GEM-based Liquid Hole Multipliers
E. Erdal, L. Arazi, M. Rappaport +3
The bubble-assisted Liquid Hole-Multiplier (LHM) is a recently-introduced detection concept for noble-liquid time projection chambers. In this "local dual-phase" detection element,…
First results of a large-area cryogenic gaseous photomultiplier coupled to a dual-phase liquid xenon TPC
L. Arazi, A. E. C. Coimbra, E. Erdal +6
We discuss recent advances in the development of cryogenic gaseous photomultipliers (GPM), for possible use in dark matter and other rare-event searches using noble-liquid targets.…
Mapping the Sensitive Volume of an Ion-Counting Nanodosimeter
Reinhard Schulte, Vladimir Bashkirov, Sergei Shchemelinin +5
We present two methods of independently mapping the dimensions of the sensitive volume in an ion-counting nanodosimeter. The first method is based on a calculational approach simul…
