THE SPARKER, A DEVICE TO OVERCOME THE MULTIPACTOR DIFFICULTY IN STARTING THE OSCILLATOR OF A CYCLOTRON
Technical Report

OSTI ID:4096794
A simple device was added to the cyclotron to shock the dee system into oscillations of such an amplitude that the multipactor loading would be effective. It consists of a separate small coupling loop inside the dee stem tank near the oscillator coupling loop, oriented with its plane perpendicular to the axis of the tank. A condenser and air spark gap are connected to the loop so that a high frequency discharge through the loop occurs when a spark jumps. This induces a surge of high frequency current both in the walls of the dee tank and in the plate and grid circuits, with the result that the dee circuit begins to oscillate with a dee voltage amplitude of several hundred volts. The oscillator then begins to carry the voltage on up to its full value. (W. L.H.)
