Abstract
Comparing with single beam klystron,multi-beam klystron (MBK) can operate at lower beam voltage,and has smaller volume and weight.To satisfy the requirement of high energy proton accelerator for spallation source and ADS (accelerator driven sub-critical system),the design and calculation of a P-band 1.2 MW MBK was made in Institute of Electronics,Chinese Academy of Sciences(IECAS).By using 30 beams,the P-band MBK can work at beam voltage of 35 kV with cathode loading of ＜2.5 A/cm2.By using 5 cavities (one of them is 2naharmonic cavity),the P-band MBK can obtain peak power of 1.282 MW,efficiency of 69.7 ％,and gain of 45.6 dB with interaction section length of 600 mm.It makes the total length of MBK less than 2000 mm.The design consideration and calculation results are present in the paper.Also the comparison among MBK,multi-beam-IOTand single beam klystron was made.关键词
