Abstract:

The objective of this program is the development of 3.2 millimeter wave tubes having the smallest possible volume, lowest possible weight, and the lowest potential production cost without compromise of performance. The program consists of two parallel phases, the first being concerned with the 100 W TWT and the second with the 1 kW TWT. Considerable progress has been made in the design of the 100W peak 50W avg. power TWT, designated the 982H. The basic rf circuit has been tentatively designed, subject to further evaluation by testing with scaled X-band parts. The windows, tapertransformer, collector, and magnets have been designed. The electrical design of the gun is nearly complete, and the mechanical layout must still be prepared. A thicker 0.020 in. vacuum sheath will be used on this tube, rather than the normal 0.005 in. thick sheath which has been used on most Hughes EDD mm-wave TWTs to date. The thicker sheath will give greater structural stability to the circuit. Also, the magnetic pole pieces will be brazed directly to this sheath, creating precise and secure alignment of the magnets to the rf circuit.
