摘要
In comparison with a photomultiplier tube, the resolving power for photoelectron peaks is largely improved by a silicon diode bombarded with electrons from a light-detecting photocathode. With photoelectrons accelerated to 13 keV, the measured variance of the electronic noise is 1.29 keV and the total variance of the photoelectron peaks is 1.81 keV. The continuum part of the photoelectron spectrum is explained by a backscattering process on the diode surface. The contrast function shows that up to 14 photoelectron peaks can be resolved.
