Design of a 10 GHz, 10 MW Gyrotron.

Abstract

A design for a 10 MW, 10 GHz gyrotron with a maximum pulse length of 100 microsec has been described. The design appears without major risks. Two cavities and their respective electron guns have been investigated. The TE (1,4) cavity is more satisfactory when it is examined without regard for mode competition, but is predicted to suffer strongly from this problem. The TE(1,3) cavity may operate satisfactory with suppression of unwanted modes. although prudence indicates that suppression methods be prepared. The gyrotron using this mode should have good efficiency ( about 28%) and a margin of safety is power of over 40%. The gun should produce a beam with an acceptable velocity spread, and its operation is predicted to be stable to changes of current and voltage. Therefore, the TE(1,3) mode will be used initially as the operating mode. Keywords: Relativistic gyrotron; High power microwave generation.
