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
