Shift plan 14/12/2011

Access: 1 - 1.5 hours

• Low energy green alignment post IP - remove new recollimating lens, replace turning mirror on stage, turn beam onto ceramic beam dump.
• Check reasonable laser signal on APD.
• High energy laser transmission check through IP (measure with energy meter + attenuator).
• Reference laser position with screen (including horizontal movement check).
• Replace final focus lens with undamaged one - check if threads on lens mount need lubricating.
• Get red alignment laser down beampipe to check OTR alignment.

Beam time: 2 hours max.

• Check background level (previous week ~ 1V) and tune for low background, aiming for 500mV.

Beam time: 30 - 45 minutes

• OTR images with < 700ms exposure time, calibration, quick quad scan to minimise beam size.

Beam time: remaining ~ 4 hours

• Laserwire scans - timing, alignment, vertical scans (~ 2 um steps), then if no signal alter beam pointing with magnets to try and hit window.
• If signal, quad scans, telescope scans, lots of data taking.
