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

Details: https://jeffersonlab.sharepoint.com/:w:/s/CIS/EdSMQSye_MZOlmzGsWbVn78BbjYtBI-zQsLDgWCXhq5ZQQ?e=3lLO27

  • 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 up to the 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
  • (Jerry, Joe) Test 200 keV PSS kicker magnet https://opsweb.acc.jlab.org/CSUEApps/atlis/task/22061
  • (Max, Yan) Evaluate QCM
