Agenda and Notes
1. Operations Status and Summary
Recovery Plans. Still Diagnosing Cryo problems. Definite sensor wire connection failure. Only 4 K work over the summer. Probably no 2 K ops until late summer. Still need to open up and look to make sure no damage. Cryo Review first week June to help on turnon operations again.
Twenty years plan for meeting performance and maintaining 12 GeV performance. Gradient Achievement and maintenance plans being developed. Need 8 New C75 modules over 5 years. 37 weeks/yr goal. Obselescence plan will also be included (old analogue to digital) Presentation is two weeks. Potential new cold box in plan (calling infrastructure might make funding easier)
4 K running might be OK for addre3ssing operability issues. More extensive running may be in the offing.
2. "Staytreat" Discussion Preliminary topics list have been uploaded. Meeting has been drifting back towards end of summer. Now August 2-3.
3. Performance of C57
Gradients of two reworked "C57" cavities are topping out in mid-teens of cavity gradient. Full upgrades of LLRF and klystrons not needed (still probably like hot klystrons on these cavities.) Presentation next week.
4. Backing Pump Discussion
Additional data mining performed. Consult with Benesch and . Gigi marcy looked at geome34try and suggested ,. Capacitor pumps on order anyway. Go through and sellect a promising module for test. 4 weeks plan will be presented. Next Steps
Waveguide Backing Pump Discussion
5. Lead Collars (Legg)
Radiation shielding at end of C100s has been explored by Legg.
preliminary design has been completed. goal to help save girders.
New module will be C57. More planning for the 2018 Module needed.
4. Particulates reporting; SRF in Dirty Machine Workshop: HZB. Josh, Tom, and Thomas in two weeks.
Action Items
Leadership of quenches. Offline discussion.
