Paper Abstract

An optically powered fireset has been developed for the Procyon high explosive pulsed-power generator at Los Alamos National Laboratory. The fireset was located inside the generator where large magnetic fields are compressed to create amplified current pulses. No energy sources were allowed inside the experiment and no wire connections can penetrate through the wall of the experiment because of the high magnetic fields. The compression was achieved with high explosives in the experiment. The fireset was used to remotely charge a 1.2 (mu) F capacitor to 6500 V. The capacitor was charged by using two 7 W fiber coupled GaAlAs laser diodes to illuminate two fiber coupled 12 V solar cells. The solar cell outputs were connected in parallel to the input of a dc-dc converter. The voltmeter, powered by illuminating a third 12 V solar cell with 1 W laser diode, was used to monitor the charge on the capacitor. The voltage was measured with a divider circuit, then converted to frequency in a V-F converter and transmitted to the control room over a fiber optic link. A fiducial circuit measured the capacitor firing current and provided an optical output timing pulse.
