Schedule
- CEBAF SAD runs from Feb 8 - Jun 8 (about 4 months) media:210112_SAD_timeline.pdf
- Jason Willoughby is installing bright white task lighting w/ wall dimmer from laser hut to fc#2
- Install group may remove 5D line in prep for Phase 2 https://opsweb.acc.jlab.org/CSUEApps/atlis/task/22161
- Tunnel jobs during first ~month of SAD
- Tomasz is upgrading RF https://opsweb.acc.jlab.org/CSUEApps/atlis/task/21376
- CIS has two major vacuum jobs
- Beam base jobs follow, accomodating PSS
Vent VBV0I02 - VBV0I07
- Marcy write ATLIS
- Coordinate groups to remove/stow items
- Coordinate with SRF before venting
- Dry run the entire sequence of jobs
- Prep all the parts for vacuum job in tunnel
- Vent through QCM
- Work w/ S&A to remake A2 gasket
- Rework IYG0I02, remove top-hat, align YAG screen per Dennis
- Work with S&A to align YAG screen
- Work with S&A to install, align IHA0I02
- Check viewer and harp before and after pump down, repeatedly, carefully
- Pump down and leak check
Vent Mott chamber
- Joe write ATLIS
- Coordinate with S&A to check gold ladder fiducials
- Coordinate with Scott to disconnect diamond ladder controls
- Dry run the entire sequence in tunnel
- Prep all the parts before venting
- Vent chamber slowly for existing gold target
- Remove diamond ladder
- Rebuild lower section of Mott (tube + window)
- Last step install and align gold ladder
- Slow pump down, check motion controls of ladder, leak check
- Long pump down
Upgrade Gun2 loading chamber
Beam Based Tests
- (Shukui, Joe, Tomasz, Reza) Install and test mode locked fiber laser https://opsweb.acc.jlab.org/CSUEApps/atlis/task/22830
- (Dennis, Ken, Alicia) Use harp to study Wien optics and test match
- (Dennis) Evaluate optics of Lakshmi's new 15 deg DM dipole vs. existing DS dipole
- (Max) Use BPM, Harp/lens to quantify beam deflection & Twiss vs. laser spot location
- (Riad, Sarin) Use BPM's and Wiens to test different/new PS to suppress line noise
- (Gabriel, Carlos) Do you need data for Wien paper?
- (Jerry, Joe) Test 200 keV PSS kicker magnet https://opsweb.acc.jlab.org/CSUEApps/atlis/task/22061
- (Yan) Evaluate QCM
