Abstract

Future linear colliders have hard requirements for the beam transverse position stability in the accelerator. A beam position monitor (BPM) with the resolution better than 0.1 micron in the single bunch regime is needed to control the stability of the beam position along the linac. Proposed BPM is based on the measurement of the asymmetrical mode excited by a single bunch in the cavity. Four stages of signal processing (space-, time-, frequency- and phase-filtering providing the required signal-to-noise ratio) are used to obtain extremely high resolution. The measurement set-up was designed by BINP and installed at ATF/BNL to test experimentally this concept. The setup includes three two-coordinates BPM´s at the frequency of 13.566 GHz, and reference intensity/phase cavity. BPM´s were mounted on a support table
