Abstract
Discusses the time resolution of p-i-n photodiodes applied as electron detectors. The rise time was found to be of the order of 1 ns, which is equal to that in the case of photon detection. However, it appears that in electron detection the initially fast decay turns over in an exponential decay with a time constant of about 30 ns. A simple algorithm is presented that corrects the recorded waveform for the effects of this tail.
