Concept and realization of 2D and 1D detector readout systems with new adjustment and calibration features

Abstract

We present the concept and report on the realization of the new 2D readout system for the CERCA 128 × 128-7.5 mm 2 -element neutron detection chamber installed on the SINQ-SANS instrument. The adjustment and calibration of the detector response is performed iteratively under software control. This new development includes an additional time of flight (TOF) option. Based on this successful design, we are now developing a 1D TOF readout system for the SINQ-POLDI detection unit.
