Overview
R1443 is a 32/64 channels Charge Sensitive Preamplifier in a 19ʺ rack unit (120/230V 50/60Hz AC Powered). It has been developed in collaboration with Institut Laue-Langevin in Grenoble, France, and it is specifically designed for operating with neutron detectors as He3 or BF3 tubes. Given the number of input channels, it can handle up to 16/32 position sensitive tubes, each tube having two outputs, one for each end.
The output signal of each channel is an exponentially decaying signal with a typical decay time of 1 us. This guarantees an excellent performance even at high rates exceeding 100 kcps. The output of this preamplifier is typically readout by ADC and Digital Pulse Processing electronics in order to perform specific filtering to achieve the best charge, timing and axial position measurements.
