  1. Primary Beam Test of Cavity BPM Shu-xin ZHENG Accelerator Laboratory Tsinghua University

  2. Content • Introduction • Main parameter • Primary Beam Test

  3. introduction • Goal • XFEL: m • ILC : nm • Program Collaborated between SSRF/SINAP and Tsinghua University

  4. Cavity Parameter

  5. Partially welded

  6. Cavity BPM Picture

  7. Microwave parameter

  8. Primary Beam Test • Laser RF Gun • Charge: 700pC • Dark current: 20nC • Position jetter: 0.1mm • Length: 4~7ps

  9. Experiment Setup Deflecting Coil YAG Screen Cavity BPM RF GUN 1.5m 0.15m

  10. Beam Signal

  11. YAG Screen Monitor

  12. Beam Position on YAG vs. Coil Current =0.24mm

  13. Position Signal

  14. Resolution • Voltage noise • v=1.8mm4.7mV/mm=8mV • Mainly from dark current? • Resolution@0.7nC • 1.8mm/11.6=0.16mm • Error • Dark current • Trace tilt

  15. Thank you for your attention
