WCM-based Bunch Charge Monitoring A. Kalinin EMMA tasks, experiments, and procedures 23 August 2012
From 19 April 2012: The WCM/Kicker cables are adjusted in length: IL WCM (beam propagation time to K1, =6ns) + L (to emmascope3) this cable was faulty! to IN4 Injection: splitter emmascope1 L K1 to IN1 L K2 toIN2 L1 ATT S toIN3 Extraction: IN4 L K1 to IN1trigger from IN4L K2 to IN2 L2 S toIN3
Upper: BPM-based Bunch Charge Monitoring (IL and Ring only) • Lower: WCM-based Bunch Charge Monitoring (including the extracted bunch) • For a train ~100 bunches, calibrate against IL FC. • Use!
