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.
