Recovery C8 failed completely. We are moving to complete new C8 and prepare it for installation. Work remaining is low and high side pressure tests which will be completed under the C9 TOSP as planned. Once pressure tests are complete the unit will be turned over to operations to install and clean carbon. In parallel EI&C will check out all the wiring and Alicia and Nate will work out a plan for installation to be approved by Mat when he returns. C8 pressure tests should happen today and then it will be turned over to OPS to install and bake carbon.

Attendance

Thompson, Creel, Dixon, Oren, Michalski

Wright doing utubes

Agenda and Notes

1. Operations

LINAC

Magnet power supply repaired.

A warm window on 2L06 failed and required utubes to support repairs. 2L07 also ingested air into the beam line and now requires cryo cycling

The test plan to raise pressure in the linac failed on the first step and pressure was again lowered.


CHL1

Old recovery C8 was removed and new C7 was installed yesterday. Piping and electrical work is expected to take about another week.


CHL2

Normal


ESR

Hall C SHMS Q2 utubes installed yesterday. Cooldown will start today.


CTF

Plant operating normally.


HDR

Plant operating normally.


2. Projects

UITF

Warm return VJ line section above cryomodule should be installed by COB Friday. Vacuum pump tie in was completed last week.


MSU

2K Cold Box design work shifted over to Michael. Contractor on site installing cold box tie ins and platforms.


LCLS2

Installation work for the cryo plant was officially moved to the SLAC team. The team is currently evaluating the bids on some of the utility support equipment. Bayonets etc. are complete and we are going to ship them to PHPK as soon as possible. Dana will advise when paperwork is done. The recovery compressor parts purchasing is underway. Work has begun on the frames.


3. Manpower

The new EE regular employee and ECAD contract employee started on Nov 1.

We had an interview with Dr. Wang.


4. Info from Will

1. Appraisals and new expectations 2. Watch all spending on OPS and ENG accounts


4. Other

Gave STEM talks with LN2 demonstrations to three high school science classes this week.
