(5) Initial Data: BPM Vibration July 15, 2009 time (sec)BPM position (nm) 35 nm rms points every 1ms projection points every 1ms time (sec)BPM position (nm)

(6) Initial Data: Overnight Stability July 15, 2009 time (sec) BPM position (nm) 1m1m Scatter around Central value RMS: 41nm

(7) ~One Hour run today July 15, 2009 time (sec)BPM position (nm) RMS: 46nm

(8) Camera Data from Today July 15, 2009 x(1) – x(2) (microns)y(1) – y(2) (microns)

(9)Status Interferometer & Camera systems aligned and ready to record data DAQ problems solved –(needed TTL trigger input; used NIM converter module) –DAQ now in final configuration for data-taking For each beam pulse, we will take 3 interferometer points spaced by 0.5 ms after Kicker Fire Pre-Trigger camera data will be updated every 30 seconds with an average position computed in the DAQ –One Remaining Issue: Define and test PV read/write/log with EPICS IOC Domo Arigato Gozaimasu to Terunuma-san and the KEK Team for all of their help!
