11/14/2017 Meeting

Attendance

Nusair, Dixon, Thompson, Creel, Radovic, Dixon, Butler, Radovic, Wijeratne, Norton, Laverdure , Schleeper, Yang, Perry,

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

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 can be blanked when CHL1 is down and water is isolated. -Vacuum line can be isolated when CHL1 cold box is off line and warm.

4. JLAB External Group Projects

UITF (Perry, Radovic, Carlton)

Thermosiphon being installed. Utubes are being fabricated. The electrical controls work will start after guard vacuum.

5. JLAB External Lab Projects

LCLS2 (Dixon)

Recovery compressor skids

Guard Vacuum Skid

Bayonets
