Goals

The purpose of this weekly meeting is to discuss plant operations and group projects with the cryogenics group managers and supervisors. During this meeting we will discuss ongoing and future projects, priorities, manpower, schedules, expenditures, and problems.

Agenda and Notes

1. Safety

2. Schedule

Plan is to run CHL1 and CHL2 at 2K until mid March.

3. JLAB Internal Group Projects

GPP (Yang, Thilan)

Kinney Pump Relocation

Main Gas and Recovery Gas Management Systems

CTF C3 Interstage Heat Exchanger Removal

Install redundant 12V power supplies for cryo cons

CHL to FEL Utubes (Perry, Corey)

CHL1 Regeneration Skid Removal (Schleeper, Thompson)

-Helium line can be isolated and blanked at anytime with LOTO. -Water lines isolated. -Vacuum line can be isolated when CHL1 cold box is off line and warm.

Change SC1 and SC2 batteries change

4. JLAB External Group Projects

UITF (Perry, Radovic, Carlton)

Thermosiphon installed and pressure test complete. Utubes have been fabricated. Controls need to be finished.

5. JLAB External Lab Projects

LCLS2 (Dixon)

Recovery compressor skids electrical is being cleaned up

Guard Vacuum Skid electrical is about 95% complete

Two water skids are in checking phase

Bayonets. Jay is working slightly ahead of schedule.
