Abstract

We have successfully detected images of tracks of photoelectrons from the 22 keV and 30 keV X rays of ¹⁰⁹Cd and ²⁴¹Am, utilizing an optical imaging gas detector with a CCD camera. Most of the 30 keV photoelectrons have track lengths greater than 1 mm in xenon gas. The images of the tracks contain clusters of pixels, and the brightest of these clusters, for each track, were investigated in detail. It was found that the geometric center of these clusters differed from the point of maximum energy loss
