Agenda and Notes

1. Operations

LINAC

MCC and SRF and RF working to understand heat and Q values. They have been doing some studies to gather data.

CHL1

Normal.

AL/S2M have reported an alignment problem with the CC4 shaft repair. We are gathering information and brainstorming.

CHL2

Normal

ESR

Normal.

Transferline valve CAMAC issue has been resolved.

Issue reported with T2 not spinning down correctly following a trip. We have met and reviewed graphs and discussed possibilities for why the turbine inlet valve is no longer sealing. We have a plan to schedule a date to operate using the transferline, shutdown T2, warm it up, and check the operation and seating force of the inlet valve. If the soft goods are failing it would require a plant warm up to repair. We will reaccess after the warm up and adjustments are tested.

CTF

Normal

Kinney #2 ring pump spun a bearing. The ring pump has been moved to the repair facility in Chesapeake. There is no spare Kinney at CTF until it returns.

The LCLS2 cryomodule is under test.

HDR

Normal.

Solenoid is ramping up to receive beam.

2. Projects

UIM

Shutdown scheduled for Feb 17. We are finalizing the detailed daily work plan.

UITF

Possible space conflict between electrical conduits and mechanical for LN2 subcooler. Conduits with wires are already installed and supporting control system. Chris is investigating. The fab shop recovery compressors are moving along.

MSU

Working to accumulate the pressure systems documentation. Concerns over information sharing.

LCLS2

Cold compressor review in France went well. Only real surprise was the seismic results forced the manufacturer to increase the thickness of the base plates. Smith Group is an A&E firm to help SLAC put together the installation package. SLAC will not be able to get an installation contract in place until ~Sep even though equipment begins arriving in Apr.

Korea

Kelly is attending a review in S. Korea.

3. Manpower

New engineer arriving mid Feb. He will work 50% of his time on EI&C for LCLS2 and remainder on OPS.

4. Info from Will

1. LN2 contract proposals are in.

2. Will has asked Mat to put in PR for nitrogen through June.

3. New director starts Apr 3.

4. Funding could impact summer shutdown schedule possibly forcing the shutdown of CHL2 earlier than the May bill read.
