A two-stage voltage divider having a voltage measuring capability on the order of 100 kV and a risetime of 250 psec has been used to measure submicrosecond pulses on a pulsed electron accelerator. The divider uses a copper sulphate solution high-voltage divider, and a secondary divider made of carbon composition resistors. Measurements have been made indicating the solution divider is useful with fields of 30 kV/cm and with subnanosecond risetimes.
