US Patent:

48945862, Jan 16, 1990
Filed:

Feb 18, 1988
Appl. No.:

7/157644
Inventors:

Carl R. Crager - Montoursville PA
Kenneth F. Ramacher - Montoursville PA
Frank A. Zawada - Williamsport PA
Assignee:

Litton Systems, Inc. - Beverly Hills CA
International Classification:

H01J 2534
H03F 354
US Classification:

315 3951
Abstract:

The present invention discloses a cross-field amplifier having an anode and cathode with a pair of permanent magnets which create a magnetic field perpendicular to an electric field created between the anode and cathode. An electric bias circuit is connected between the cathode and a power supply that normally supplies energy to an oxygen source within the amplifier. This bias circuit supplies a negative DC voltage to the cathode. After the amplifier is turned off, the DC bias holds electrons within the interaction area between the cathode and anode for supplying the electrons needed to quickly restart the amplifier.
