High Resolution Cavity BPM for ILC Final Focal System (IP-BPM)

Abstract

IP-BPM (Interaction Point Beam Position Monitor) is an ultra high resolution cavity BPM to be used at ATF2, a test facility for ILC final focus system. Control of beam position in 2 nm precision is required for ATF2. Beam tests at ATF extraction line proved a 8.7 nm position resolution.
