Capacitor bank Faraday rotator C amplifier, K1 system (23 Jan 1976) (Engineering Materials). [2 drawings]
Drawings of the charging and firing circuits used in the LLL CYCLOPS laser system to energize the 20 cm aperture Faraday rotator magnet coils are presented. A series LC discharge circuit is shown, where C is the bank capacitance and L is the Faraday rotator inductance itself. The desired current waveform is a damped sinusoid lasting for several cycles. In a modified design, diodes are inserted in parallel with L. The desired current waveform smoothly rises to a peak value, then decays exponentially with time constant L/R, where R is the series resistance sum of coil, cables, and forward biased diodes. In practice, both circuits are used in the same manner. C is typically charged to 20 kV; peak current through L is a few kA; the desired magnetic field within L is 27.5 kOe.
