Improved Dual-Mode Electron Gun.

Abstract

An advanced non-intercepting gridded gun was designed, fabricated, and preliminary tested. The use of magnetic flux in the cathode region preserves the beam diameter when the grid voltage is reduced for a lower power mode of operation. This will result in a more stable TWT performance, since the gain difference associated with the two modes is significantly reduced. (Author)
