Abstract

The construction and evaluation of a cooled CCD detector for 120 keV electrons using a tapered fibre optics is described. It has been used for accurate recording of electron diffraction data, for which it is a nearly perfect detector. The results suggest that the degree of tapering used could be increased considerably without loss of sensitivity, and that such an instrument might then also become a nearly perfect detector for image recording where, at present, the point spread function still limits the performance.
