Muonic hydrogen cascade time and lifetime of the short-lived state
L. Ludhova, F. D. Amaro, A. Antognini +24
Metastable muonic-hydrogen atoms undergo collisional -quenching, with rates which depend strongly on whether the kinetic energy is above or below the ${2S}\to {2P…
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…
Operation of MHSP multipliers in high pressure pure noble-gas
F. D. Amaro, J. F. C. A. Veloso, A. Breskin +2
We report on the performance of a Micro-Hole & Strip Plate (MHSP) electron multiplier operating in pure Xe, Kr, Ar and Ne at the pressure range of 1 to 6 bar. The maximal gains at…
