THE MODIFICATION OF THE METHOD FOR DESIGNING THE FILTER TYPE OUTPUT CIRCUIT OF BROADBAND KLYSTRONS AND THE CALCULATION OF GAP INTERACTION IMPEDANCE

In this paper, we propose a new eriterion and a method for designing filter type output circuit of broadband klystrons. From this, we ean obtain an output section which satisfies the requirement of klystron designs, and have good impedance-band-width characteristies. From equivalent circuit, we can directly calculate the gap in-teraction impedance, and obtain the effect of parameters of the output circuit on which the impedance-bandwidth characteristies depends. According to caleulated curves, we can get optimum results through adjusting the parameters of output circuit in the actual manufacture.
