Abstract
The klystron in the Deep Space Network 400-kW transmitter subsystem uses a resistor to hold the modulating anode at ground potential. The resistor is connected to the klystron modulating anode through a high-voltage connector; in the past this resistor has been mounted in an air dielectric environment and has been subject to physical damage. If a cathode arc occurs, the arc forms between the cathode and modulating anode, the modulating anode potential is biased to the potential of the cathode by the arc current in the modulating anode resistor, and the arc is extinguished. The modulating anode resistor will have high-voltage (65 kV) across it during an arc. This article describes a new method in which the resistor is mounted in an enclosed cap on the side of the klystron socket tank, eliminating the above problem.
