High power C and X band Radar Helix TWTs
ABSTRACT This paper deals firstly with the C band TWT delivering 25 kWp, 1100 W average between 5.4 and 5.9 GHz . Two prototypes were delivered and integrated. The second topic of this paper is the X band TWT delivering 9 kWp, 600W average between 9.45 and 9.95 GHz. This tube has been qualified in 2007 .

ABSTRACT: This paper presents theoretical and experimental methods for the design and optimization of gridded Pierce electron guns. The design of periodic permanent magnet (PPM) focussing systems to control the nonlaminar beams originating from such grided guns is discussed. Simplified relationships are developed which directly couple the, heretofore separate, gun and PPM focusing design problems.IEEE Transactions on Electron Devices 04/1984; · 2.06 Impact Factor
