FAST, REAL-TIME MULTICHANNEL SCALER, CONSTRUCTION AND APPLICATIONS

The construction of a fast, real-time multichannel scaler and its appl ication to the analysis of signals composed of series of pulses are de scribed. 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 repe tition rate are up to 32 bits and 50 per second, respectively. Applica tions to laser deposition/ionization and three-photon-ionization exper iments involving pulsed laser sources are briefly discussed. (C) 1996 American Institute of Physics.
