Pagination or Media Count:
The EV-64 high-intensity light pulse source, a new version of the EV-39, is presented. The EV-type light pulse sources are based on capillary discharge with the evaporation of walls. The EV-64 has a capillary 2 mm in diameter in a textolite plate 10 mm thick. The capillary is mounted in a discharge chamber 1000 mm long and 508 mm high. The pulses from a discharge current of 9 to 10 k amp between graphite electrodes 14 mm in diameter, fed from a battery of capacitors at a rated voltage of 5000 V, produce an output of radiative power of 82 wt at a pulse duration of 1.4 msec. The power supply circuitry, which is composed of a system of LCR circuits and primer discharge gaps, is described in detail.
