HIGH-POWER HYBRID MULTIPLE-BEAM KLYSTRON FOR PHASED ARRAYS
Abstract
The gun design computer program was refined to include the effects of dimensional errors caused by thermal expansions or by tolerance buildup; these effects were investigated both theoretically and experimentally. Based on the results of this investigation, a cathode mounting and jigging system has been devised which will allow any cathode of the 15-beam tube to be removed and replaced, with the necessary accuracy, without disturbing any other cathode. The effect of unintended detuning of cavities (either by thermal effects or manufacturing tolerances) on the phasing in the output waveguide was investigated on the computer. It was found that this could be a serious problem- -at least one satisfactory single-beam tube design, which has been published, would be unusable as a unit of a multiple-beam tube for this reason--but the specific design (No. 86) that we are using is found to be remarkably insensitive to minor detuning. The basic design of the modulator for the 15-beam tube is described. A massive, simple, conventional line circuit discharged by three GL- 7890 thyratrons will be used.
