A complete 16-channel MCA for SDD and transistor-reset detectors on the x5560 family
Introduction Silicon Drift Detectors (SDD) and other low-capacitance X-ray detectors are usually read out by transistor-reset (pulsed-reset) charge preamplifiers: instead of a continuous discharge through a feedback resistor, the integrator output ramps up with the detector leakage current and with every absorbed photon, until a reset transistor brings it back to the starting level.
