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
