Multiflash system

摘要

A multiflash system including an arc discharge flashlamp having an elongated tubular envelope and containing three electrodes. A direct current voltage source comprising a large storage bank with positive and negative terminals is connected across two of the electrodes, and a storage capacitor is connected between the third electrode and the negative terminal of the source. The capacitor-connected electrode defines a first arc path with the electrode connected to the positive terminal of the source and a second arc path with the electrode connected to the negative terminal of the source. Trigger pulses are applied to the lamp so as to alternately energize the first and second arc paths, the storage capacitor being charged when the first arc path is energized to flash and discharged when the second arc path is energized to flash.
