Fast, real-time multichannel scaler, construction and applications

The construction of a fast, real-time multichannel scaler and its application to the analysis of signals composed of series of pulses are described. The device allows measurements in time intervals of up to 1.3 ms with a single time-channel width of 5 ns and accepts input pulses of 2 ns in width. The capacity of the single time channel and the repetition rate are up to 32 bits and 50 per second, respectively. Applications to laser deposition/ionization and three-photon-ionization experiments involving pulsed laser sources are briefly discussed. (C) 1996 American Institute of Physics.
