Abstract :
In this paper, the development of X-band and W-band sheet beam klystron (SBK) is introduced thoroughly in IECAS recently. The compact planar PCM and closed PCM system are used to focus the sheet beam for both of two types SBK. For the five multi-gap-cavity X-band SBK (XSBK), the cross section of beam is of 50mmx4mm, and with the beam voltage of 150kV, beam current of 100A, the designed output power is about 4.6MW with the gain of 39.6dB and efficiency of 30.7%. The XSBK has been manufactured and tested successfully and the output power is about 2.8MW with the beam voltage of 123kV and beam current of 70A. For the seven multi-gap-cavity W-band SBK (WSBK) with the beam cross section of 10mm×0.5mm, the designed output power is about 30kW with the beam voltage of 75kV and beam current of 4A the gain and efficiency is of 40dB and 10% respectively At, present the WSBK has been manufactured, and the hot test is being processed.
