Paper Abstract

When optimizing equipment in which 'fast grating' is used, it is important to discriminate between the 'speed' of the module and the speed of the electrical gate-pulse unit. D.E.P. has therefore developed a method to measure the speed of the module independently of the gate- pulse unit. D.E.P. measures, during the switching on of the module, the time delay between the center and the edge of the module, which we call the iris delay. Even with an electrical gate-pulse of 3 nsec rise-time, we can measure an iris delay down to 0.2 nsec. The shortest pulse-width for which a module can be used is about 2 or 3 times the iris delay. This measurement is done with a pulsed solid state laser. The laser is fired with a variable delay with respect to the gate pulse on the tube.
