goal

– measure beam jitter at the focal point of ATF2

– produce a feedback signal for beam stabilization requirements

– ultimate high resolution (a few nm)

– less sensitivity for beam angle special cavity BPM

– rectangular shape (X:5.7GHz, Y:6.4GHz)

– thin cavity for angle signal reduction

– small beam tube for high sensitivity status

– various properties were checked with beam (position sensitivity, angle sensitivity, etc.)

– 8.7nm reslution was achieved by 3-bpm measurement

1st Asian ILC R&D Seminar proposed and accepted by CUPSteering Committee in this year.

The purpose of this seminar is to promote Asian ILC accelerator R&D as multilateral collaboration (China, Korea,India and Japan).

Asian contribution into ATF and STF as ILC R&D Test Facility will be discussed in this seminar.

1st Asian ILC R&D Seminar is this Joint Workshop in Beijing.We hope following Seminars are agreed with our colleagues. 2nd Asian ILC R&D Seminar will be held in Korea.3rd Asian ILC R&D Seminar will be held in India.

Thank you very much.
