Abstract
A protection arrangement for a high voltage tube includes a low inductance disk resistor connected in series with the anode of the tube. When an electrical discharge occurs within the tube, the increased anode current flows through the resistor which absorbs much of the potentially harmful energy surge. The resistor is a disk resistor comprising two counter-wound planar spirals of resistance wire electrically connected in parallel and counter-wound with respect to one another. Connection arrangements are provided to both electrically and mechanically connect the resistor to the high voltage tube.

A high voltage tube power assembly comprising:
- a high voltage source including a high voltage conductor and a return conductor, said source and said conductors having a combined resistance;
- a high voltage tube having an anode and a cathode;
- a socket for said high voltage tube;
- means for connecting said return conductor to said cathode;
- a low inductance resistor comprising a first electrical terminal, a second electrical terminal and a resistance substantially equal to the combined resistance of said high voltage source and said conductors connected between said first and second electrical terminals;
- means for attaching said resistor to said socket;
- and
- means for connecting said high voltage conductor to said second terminal, and for connecting said anode to said first terminal.
