High dynamic range diamond detector acquisition system for beam wire scanner applications / Sirvent, J L (CERN ; Barcelona U.) ; Dehning, B (CERN) ; Piselli, E (CERN) ; Emery, J (CERN) ; Dieguez, A (Barcelona U.)
The CERN Beam Instrumentation group has been working during the last years on the beam wire scanners upgrade to cope up with the increasing requirements of CERN experiments. These devices are used to measure the beam profile by crossing a thin wire through a circulating beam, the resulting secondary particles produced from beam/wire interaction are detected and correlated with the wire position to reconstruct the beam profile.
