E166 Equipment Discussion
July 8, 2005
V. Bharadwaj, K. McDonald, J. Sheppard, D. Walz
Below is a listing of what we discussed this morning. Please let me know what to change or add lest we forget.
Faraday Cup:
Check cabling with TDR
Add In/Out status into Accelerator Obstruction display
Add In/Out status into E166 DAQ
Spectrometer Jaws
Check Lo E functionality
Fix disconnected shaft-motor coupling and test
Add Jaw positions to DAQ
Target Lens
Slide lens upstream by about 1 cm; rotate Target assembly as necessary
Reposition taraget ladder within assembly to reduce distance between targets and lens
Do not need more current
Target Assembly
Add 0.25 r.l. thick free machining W target to empty target slot
Table movers
Replace X mover steppers with larger devices
Replace X mover differential screws
Lubricate X and Y mover mechanisms
Carefully monitor changes in table/undulator/drift tube positon w/ dial gauges and or alignment scopes when doing work
OTR
Email Bill and Peter as to whether or not they want to replace existing 1 micron thick screen with a thicker OTR /radiator screen
Add a thick
Add In/Out status into Accelerator Obstruction display
Add In/Out status into E166 DAQ
In Vacuum Radiator/Blank, rotating Brems. Radiator in vicinity of OTR
Photon Line
Add Si quadrant detectors to facilitate photon line acquisition, tune-up, and monitoring
Fiducialize photon line collimators for alignment
Reinstall photon line collimators
Model alignment issues associated with the additional collimation
Beam Energy
Find out what prevents machine from reliably operating at 50 GeV
Regardless of energy at September start (46.6 GeV or 50 GeV) run with all 7 FFTB dump line dipoles energized, as per June running conditions.
