A concept for laboratory studies of radiation detectors over a broad dynamic-range: instabilities evaluation in THGEM-structures
S. Bressler, L. Moleri, L. Arazi +4
A simple methodology for evaluating the dynamic-range of gas avalanche detectors in the laboratory is presented and discussed. It comprises two tools: a charge injector of tunable…
Laboratory studies of THGEM-based WELL structures with resistive anodes
L. Arazi, M. Pitt, S. Bressler +3
In this work we investigate three variants of single amplification-stage detector elements; they comprise THGEM electrodes closed at their bottom with metallic or resistive anodes…
Recent advances with THGEM detectors
S. Bressler, L. Arazi, L. Moleri +3
The Thick Gaseous Electron Multiplier (THGEM) is a simple and robust electrode suitable for large area detectors. In this work the results of extensive comparative studies of the p…
First studies with the Resistive-Plate WELL gaseous multiplier
A. Rubin, L. Arazi, S. Bressler +3
We present the results of first studies of the Resistive Plate WELL (RPWELL): a single-faced THGEM coupled to a copper anode via a resistive layer of high bulk resistivity. We expl…
Beam studies of novel THGEM-based potential sampling elements for Digital Hadron Calorimetry
S. Bressler, L. Arazi, H. Natal da Luz +8
Beam studies of thin single- and double-stage THGEM-based detectors are presented. Several 10 x 10 cm^2 configurations with a total thickness of 5-6 mm (excluding readout electroni…
Optical readout: a tool for studying gas-avalanche processes
A. Rubin, L. Arazi, S. Bressler +5
Optical recording of avalanche-induced photons is an interesting tool for studying basic physics processes in gaseous detectors. In this work we demonstrate the potential of optica…
