Week 3 Operation Plan

Weekend Tasks

  • Quick signal window position inspection
  • Check laser alignment at low and high energy
  • Check laser energy transmission at high energy
  • Sort out trigger for energy meter & install it
  • Improve light leakage to OTR

  • OTR polariser + software
  • OTR filter wheel software
  • Laser energy measurement at IP
  • Laser shutter
  • Check TD2 control
  • Put extra controls in EDM

  • Monday morning - survey alignment of signal window (9:00)

Anytime Before Shift With Beam

  • BBA on quadrupoles at our location 2 before, 2 after
  • BBA data for bpms at the same time
  • Shorter exposure (<600ms) OTR - only 1 lobe?

During Shift

  • Normal alignment procedure (time, vertical, horizontal)
  • OTR confirmation of alignment
  • A couple of vertical scans

If no signal:

  • Angular scans with ZV,H, 11,10X correctors to adjust angle at LWIP.
  • Use bpm readings (with BBA) to calculate LWIP angle & position
  • Correct position with ZV,H, 1,2FF
  • Angular scans in 100microradian steps
  • Vertical scans at each angle
