N. BlaskovicFONT Meeting1 Preliminary resolution study results N. Blaskovic

Introduction Results from 31 st October for: –IPB to IPC interpolation –Two electronics on one BPM study FONT Meeting2N. Blaskovic

IPB to IPC interpolation Take jitter run at start of shift with no change to optics other than to steer beam through both IPB and IPC in both x and y Then later calibrate with waist in x and y at each of IPB and IPC Jitter runs and calibrations taken at 0 dB to 50 dB FONT Meeting3N. Blaskovic

IPB to IPC interpolation Results: –Waveforms –IPB(Y) to IPC(Y) position correlation –Interpolated y paths from IPB to IPC –Interpolated x and y jitter from IPB to IPC FONT Meeting4N. Blaskovic
