Abstract

The stroboscopic technique for measuring luminescence decay times and for time-resolved spectroscopy can be greatly simplified by using a photomultiplier which has a control mesh behind the photocathode. This makes it possible to cut off the tube output by applying a negative bias of 1–2 V to the mesh; then the tube can be gated on for short periods by applying a positive pulse of slightly higher amplitude. This eliminates the problems encountered with gating methods, in which high voltage pulses are applied to the photomultiplier dynodes. Measurements were made on two fast decay phosphors (P-15 and P-16), and the results show that this tube is quite suitable for this purpose.
