Paper Abstract

The intensity dependent pulse broadening in present day photoelectric streak tubes was explained by the author as a result of bottlenecking inside the photocathode, in the 12th ICHSPP. The theory is further explored in the light of further information since the last congress. It is established that the intensity depended pulse broadening is dependent on the photocathode quantum efficiency and that the time dispersion is dependent on time resolution limit expected from the system. Both these phenomena were expected from the theory of photocathode bottlenecking and can not be explained by Child-Langmuir space charge effects. A reciprocity failure in phosphors for short electron pulses is also reported.
