Abstract

Several fiber optic systems have been designed and implemented for the high energy density experiments at Pegasus II. The main fiber optic system developed for Pegasus II remotely controls both the charging and discharging of the capacitor discharge unit (CDU). This fiber optic system is also used to distribute the timing and firing information specific to each experiment to the operators and experimenters. The timing and firing information includes the voltage on the CDU as it is being charged, a confirmation signal indicating the CDU has discharged and common timing signals based on the output signals on the load ring of the CDU. Various fiber optic systems were implemented to transfer diagnostic information related to the discharge of the main capacitor bank to the control room. The diagnostics include the current, electric field, and vacuum pressure at the target area. Not only do these fiber optic systems provide the control and monitor signals for the experiments at Pegasus II, they have the added value of preventing premature firing of the capacitor bank, eliminating ground loops between the test area and the control room and providing overall increased operator safety.
