Development of high-gain gaseous photomultipliers for the visible spectral range
A. V. Lyashenko, A. Breskin, R. Chechik +3
We summarize the development of visible-sensitive gaseous photomultipliers, combining a semitransparent bi-alkali photocathode with a state-of-the-art cascaded electron multiplier.…
High-gain DC-mode operated Gaseous Photomultipliers for the visible spectral range
A. Lyashenko, A. Breskin, R. Chechik +3
We shortly describe recent progress in photon detectors combining bi-alkali photocathodes and cascaded patterned gas-avalanche electron multipliers. It permitted the development an…
High pressure operation of the Photon-Assisted Cascaded Electron Multiplier
F. D. Amaro, J. F. C. A. Veloso, J. M. F. dos Santos +3
We present the operation of the recently introduced Photon Assisted Cascaded Electron Multiplier (PACEM) in xenon at high pressure. The PACEM is a multi step electron multiplier wh…
Efficient ion blocking in gaseous detectors and its application to gas-avalanche photomultipliers sensitive in the visible-light range
A. V. Lyashenko, A. Breskin, R. Chechik +3
A novel concept for ion blocking in gas-avalanche detectors was developed, comprising cascaded micro-hole electron multipliers with patterned electrodes for ion defocusing. This le…
Advances in ion back-flow reduction in cascaded gaseous electron multipliers incorporating R-MHSP elements
A. V. Lyashenko, A. Breskin, R. Chechik +3
A new concept is presented for the reduction of ion back-flow in GEM-based cascaded gaseous electron multipliers, by incorporating Micro-Hole & Strip Plate (MHSP) elements operatin…
The Photon-Assisted Cascaded Electron Multiplier: a Concept for Potential Avalanche-Ion Blocking
J. F. C. A. Veloso, F. D. Amaro, J. M. F. dos Santos +3
We present a Photon-Assisted Cascaded Electron Multipliers (PACEM) which has a potential for ion back-flow blocking in gaseous radiation detectors: the avalanche from a first multi…
