DEPRESSED COLLECTOR STUDIES FOR HIGH POWER KLYSTRONS
Abstract
A technical discussion is presented summarizing the present state of the art of depressed collectors for high power tubes, and pointing out considerations to be made in an actual design. Theoretical investigations based on a highly simplified klystron beam model were carried out, and the results render interesting information on the power balance in the spent beam, the amounts of power that can be recovered by a depressed collector with a finite number of electrodes, the resulting improvement of tube efficiency, the influence of secondary electrons, the reduction of X-radiation generated within the collector and the discrimination effect of outside shielding, the effects of the collectorto-ground capacitance on resistive collector depression, and finally the effects on the inherent velocity-sorting mechanism of the spent beam under large signal drive conditions of the tube. The experimental investigations were carried out on a one-megawatt pulsed X-band klystron at beam voltages around 100 kv. (Author)
