Signal Processing for Radiation Detectors Based on Integrator with Charge Compensated Reset
This work describes the development of a Multichannel Analyzer (MCA) system based on simple analog and digital architecture that takes advantage of a novel idea for resetting a charge integrating preamplifier. The author developed a so-called Free Running Integrator, which is an integrator that allows resets to be transparent to signal processing, without loss of signal charge due to abrupt current pulse injection. Dead time and signal processing complications due to resets are eliminated. The response of the Free Running Integrator to a current impulse is a step function with no exponential decay, which makes possible the use of simplified signal processing. A prototype is described whose signal processing consists of an ADC working at a very low sampling rate followed by simple digital processing algorithm. This implementation lends itself to applications where low power consumption, low cost, and simplicity are needed.
