A Cathode Follower Power Amplifier

In circular accelerators and particularly in storage rings it is essential that the total impedance, as seen by the beam, be kept below some critical value. A model of the accelerating system was built using a single ended cathode follower amplifier driving a ferrite loaded cavity. The system operated at 234.5 KHz with a peak output voltage of ± 10 kV on the gap. The dynamic output impedance, as measured on the gap, was < 15 ohms.
