Abstract :
Measurement of wakefield is planned at the Extraction Line from the Damping Ring of ATF, Accelerator Test Facility at KEK. In this experiment, `residual´ long-range transverse wake field excited by multi-bunch beam will be measured, and will be compared with theoretical calculation of wakefields with cell-to-cell misalignment. The residual wakefield which is induced by cell-to-cell misalignment of structure. Because the multi-bunch beam from the Damping Ring is expected to be stable and extremely low emittance, we can measure a small transverse kick of 10 nrad by using 500 nm resolution BPMs and optimized optics of the extraction beam line
