ABSTRACT:
A microchannel plate detector device is intended for use in the detection of low energy electrons and negative ions in particle time-of-flight measurement systems. A vacuum isolator isolates the microchannel plate signal output from ground as well as from the vacuum chamber of the meaurement system. A coupling unit includes a pulse isolator for separating pulse signals from the microchannel plate DC bias voltage. Electronic circuitry matches the output impedance of the coupling unit to the input impedance of the measurement system signal processor, thereby minimizing reflection and distortion of high frequency pulse signals.
