Abstract :
A high Tc superconductor opening switch controlled inductive energy storage pulsed power system (IESPPS) has been demonstrated. A 500 Hz pulse train of jitter-free 75-318 ps electrical pulses was produced. We also show that the IESPPS produces a pulse compression ratio of 6-10. Compared with previous results, we have reduced the pulse width by a factor of ten and increased the repetition rate by a factor of 500 while reducing the laser trigger energy from 1 mJ/pulse to 20 μJ/pulse.
