Overview
The A1422E/F series are charge sensitive preamplifiers packaged in a 2/4 channels box. The sensitivity is 200 mV/MeV.
It is suited for silicon detectors with wide surface and high capacitance, used for nuclear and subnuclear physics experiments, where very low noise, fast response and high counting rates are required. The modules accept both positive and negative input charge pulses and provide an energy output of ±4.5 V range on 50 Ω termination (±10 V on 1 kΩ). Moreover, a test input accepts positive and negative signals for calibration purposes.
The A1422E/F is implemented into alloy boxes and feature SHV connectors for HV/IN, SMA connectors for DET/IN, TEST IN and E OUT and D-type 9 pin male connector for the power supply.
