53 Mhz measurement Requirements Measurement specifications 53 MHz bunch structure Measurement range 25 mm, 30 mm for large aperture BPMs Absolute position accuracy 1 mm + 5% of actual beam position Relative position accuracy (3 ) 5% of actual beam position Position resolution (3 ) 0. 05 mm (0. 1 mm) Position linearity within 1. 5% of the slope of the BPM response at the center of the BPM over 15 mm Long-term position stability 0. 2 mm Relative intensity accuracy 10% (20%) Measurement specifications for 53 MHz bunch structure, narrow bandwidth mode. Values in parenthesis are for high bandwidth mode, with single turn resolution. Because of the non-linearity intrinsic to the MI BPM pickups, this specification only applies when the beam is off center on only one of the planes . Applies to: • Flash, Display, and TBT modes (both flash and user defined). • Single coalesced bunch, short (7 bunch) batch, full batch, multibatch beam. Verified by_________ date

Values in parenthesis are for high bandwidth mode, with single turn resolution. Because of the non-linearity intrinsic to the MI BPM pickups, this specification only applies when the beam is off center on only one of the planes.
