“…They allow for the recognition of the x/y coincident events (position information) and the running of the SANS instrument in the stroboscopic mode (time information). The "good events" (position and time information) found together with the system-status information are transmitted to the PSI "Histo-Memory" unit [3] by special implementation of the PSI "Multidetector Interface". The data-gathering module mainly consists of a micro-controller unit (MCU) with some field-programmable gate arrays (FP-GAs) performing the required tasks.…”

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.

We have developed an ultra-fast multi-channel time-to-digital converter (mC-TDC). The mC-TDC electronics is used to read out the delay-line-based 2-D detectors of the neutron diffractometer and reflectometer TriCS and AMOR, respectively. The high time resolution of the mC-TDC (≈ 145 ps) allows the conversion of the positionsensitive detector signals into accurate 2-D scattering coordinates (≈ 2 × 2 mm 2 ). The mC-TDC also generates lowjitter time-of-flight signals and incorporates an efficient twostage pileup-rejection mechanism. Neutron rates exceeding 100 000 cps can be processed.
