Abstract

The prototypes for the nominally 300-kV pulsed power supply and acceleration cell were built and tested in order to determine critical design parameters needed for their final designs. The pulsed power supply produced a 73-ns-long trapezoidal pulse rising in 3 ns (10-90%) and having high frequency ripple of less than 2%. The power supply´s throughput jitter was 1.5 ns (1a). The cell was driven by the power supply and had a resistor taking the place of the beam loading. The cell tests showed that the ferrite had a useful flux swing of 0.45 T (20.7 mV-s) before the magnetization current pulled the cell voltage down by more than a few percent.<>
