Abstract—
A new readout system for strip semiconductor detectors has been developed based on a dedicated IDE1140 chip. The system consists of 64 spectrometric channels that provide readout of signals from detector strips. The source of the trigger signal can be either an external signal or a detector that measures the passage of an ionizing particle through the strips. The amplitude of the signal from this detector can also be used for particle spectrometry. The control and signal-readout unit for the IDE1140 chip has been designed on an EP3C16Q240 field-programmable gate array and is used for processing, storage, and transfer of acquired data. The main characteristics of the system are presented: the integral nonlinearity is <1% in the range of 5−160 fC, and the equivalent noise charge is 0.7 fC.
