Abstract

Common streak camera phosphors such as P-i 1 and P-20 have conversion efficiencies that depend on the duration of the excitation pulse. This reciprocity failure leads to the poor sensitivity that has been reported for streak camera systems. An alternative phosphor P-46 which has a very short persistence time appears to have a more linear response. In this paper we report on the conversion efficiency of these phosphors as measured with a photometrically calibrated CCD as well as a study of the rise and fall times of the phosphorescence. Excitation pulse durations range from 20 ps to 300 ms. 1.
