Paper Abstract

A reduction in the efficiency of phosphors ( P 11 & P 20 ), when used in picosecond streak tubes is reported. A loss of the order of 100 times is estimated. This is identified as the main reasonfor the inability of present day streak cameras to record single photo-electrons from the photo-cathode of the streak tube. It is suggested that work should be carried out on the efficiency of phosphors energised by sub-nanosecond bursts of electrons. The authors suspect that the use of a silicon target instead of a phosphor will vastly improve the recording ability of a streak tube as the efficiency of such a transducer is not expected to fall drastically for short duration electron pulses.
