Micromegas operation in high pressure xenon: charge and scintillation readout
C. Balan, E. D. C. Freitas, T. Papaevangelou +4
The operational characteristics of a Micromegas operating in pure xenon at the pressure range of 1 to 10 bar are investigated. The maximum charge gain achieved in each pressure is…
The Thick-COBRA: a New Gaseous Electron Multiplier for Radiation Detectors
F. D. Amaro, C. Santos, J. F. C. A. Veloso +3
The operation principle and preliminary results of a novel gas-avalanche patterned hole electron multiplier, the Thick-COBRA (THCOBRA), are presented. This micro-hole structure is…
Precision determination of the dpi -> NN transition strength at threshold
Th. Strauch, F. D. Amaro, D. F. Anagnostopoulos +16
An unusual but effective way to determine at threshold the dpi -> NN transition strength is to exploit the hadronic ground-state broadening in pionic deuterium, accessible by x-ray…
