Abstract We report on connection of the klystron wave-guide using an air-pad system. XFEL/SPring-8 LINAC uses 71
klystrons to send high power RF to a lot of accelerator. We developed the klystron modulator that combined the pulse
transformer with the high-power modulator. But total weight of modulator reached 5000 kg. The air-pad system isdeveloped to move the heavy components. We optimized the air-pad design and developed the alignment base to guidethe klystron motion during the waveguide connection.
