Bandwidth Extension of an S-band, Fundamental-Mode Eight-Beam Klystron
Abstract
We present the design of a five-cavity, broadband, high-power multiple-beam klystron (MBK) operating in S-band. The MBK uses a 32 A, 45 kV eight- beam electron gun [1] whose design has been successfully tested in a previous narrowband MBK circuit [2, 3]. The circuit was optimized using the 3D particle-in-cell code MAGIC; the predicted performance includes a 3-dB bandwidth of 6.7%, peak power of 600 kW and a gain of 33 dB. This circuit performance represents a three-fold increase in the bandwidth-power product relative to our previous circuit.
