摘要:
A pulsed voltage generator has been built for an electron microprobe for measuring rise and decay characteristics of cathodoluminescence from micron size sample areas. The pulsed voltage operation has an advantage in that excessive heating of the sample can be avoided by keeping the electron beam on the sample surface only for the duration necessary to get the full trace. Both the pulsing frequency and the pulse duration are variable continuously over wide ranges.
