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. Schedule

• Near term schedule Media:img_3163.jpg

2. Operations (A brief description of the highlights for the past week at CHL's, ESR, HDR, CTF)

Hall D compressor shutdown caused magnet to ramp down. Cause was operator error. Down time was x hours.

ESR shutdown

3. JLAB Internal Group Projects

UIM (Creel, Wijeratne)

The shutdown is scheduled from 17 Feb - 9 Apr (Dewar Full). A job briefing is being planned for this week. A presentation for the P&C Group underlined the importance of not reassigning people once the down has started.

GPP (Yang)

Designers are working on the drawings for moving the Kinney pumps. Shirley has approved the current conceptual design for the suction piping. Designer is also working on the cooling water header designs. The drawings are finished for the small warm gas tie ins that we will try to install during the Feb shutdown. Paul is working on the detailed drawings. Some are ready for review. Valves have been ordered for Kinney suction lines.

CHL2 C6 (Perry, Creel)

Its looking probable the accelerator will shutdown 22 March. If it does the C6 work will move up if not the shutdown is planned for first week in May. A fab crew is building the piping spools. for helium, water, and oil (Willy). The electrical supplies including 4160v wire, 120v/480v conduit and wire were ordered and should be on site. The on-skid conduits and wire can be installed as well as the 4160V run from the motor to the starter. The 120V and 480V home runs cannot be installed before the shutdown because the panels are energize. We are getting a price from Paul Powers for the FM contract electricians to perform this work. Perry is working up a plan for the CHL2 shutdown. Chris will have a meeting to discuss the schedule and maintaining cleanliness as much as possible. Chris tp write and coordinate approvals for pressure tests.

JLAB Guard Vac (Scheelper, Creel)

The guard vac skid is mechanically installed. The electrical power and controls need to be finished. There is one more box to install and conduit and wire to be installed. We have requested the FM electricians perform this work. Work to begin Friday. Mechanical need to add an air line run.

JLAB 3rd Recovery Compressor (Saringer, Creel)

On hold. The skid is mechanically finished. The skid is electrically 50% finished and Beizer is working on the electrical now and should be done this week. There is no funding or plan to install the machine yet. We need to verify the installation of the check valve on this compressor. Mike will finish in one week. Roland will finish the power run from compressor to starter.

JLAB recovery header rework (Saringer)

Job is being re-planned to shrink the required down time and cost.

JLAB Vaporizer (Perry)

We have most of the parts. The installation is on hold. It might be used as a filler job if things ever get light. Robert will check if there is any instrumentation and controls associated.

ESR Hall A 15K utube (Schleeper)

A new utube is being fabricated with a manual valve to replace the existing utube because it has a leak. Drawings are released but have not been delivered to Scott to see and order parts. Work needs to be scheduled.

CHL to FEL Utubes (Perry, Corey)

If a designer becomes available they will be placed on this project. It is currently in Craig's queue.

3. JLAB External Group Projects

Hall B 12GeV (Thompson)

We have been tasked with fabricating flex lines for the solenoid can. It will take approximately 4 months. (Jay). Roland is continuing to work with Ruben on solenoid can instrumentation as needed. Torus was recooled and is ready for KPP run.

UITF (Perry, Creel)

CM should be in place in 1 weeks to allow the final utube measurements to be taken. Then it will take about 4-5 weeks to build the utubes. We have the parts.(Roy) The thermosiphon can fabrication and installation is expected to take about 2 months to build and install. Likely to be Dano's crew once they complete UIM. HDIce return line is a fill work. Its low priority. Fab is working on the thermosiphon. The height of the can is sufficient. LN2 supply line is being worked right now. Drawings are in checking for the vessel. Control system has a couple of weeks of work left to do as soon as a tech becomes available. Chris will check with all parties and determine the real schedule.

CHL2 Main Compressor Oil Level Alarms (Saringer, Wright)

We are having trouble managing compressor oil levels especially when there are large ambient temperature changes. We need to work on a solution.

4. JLAB External Projects

MSU (Dixon)

We are working to accumulate the pressure systems documentation. The scope of the work is not clear. Cory and Kelly are coordinating what additional work might move to MSU from JLAB. JLAB might be picking up cryomodule design work and possible magnet work.

LCLS2 (Dixon)

We are building two recovery compressors. Due in July 17'. These will take more hours than estimated because of seismic modifications. (Issac) We are building a guard vac skid for LCLS2. Not started. Due end of October 17'(Issac)SLAC operations is interested in drafting a long term support agreement for after the machine is running. (??) Cold compressor FDR was completed last week (results unknown). PHPK is continuing to fabricate the first set of warm compressors. We might also fabricate a water skid. FDR for 2K cold box Mar 9.

5. Summer Maintenance Work Plan (Wright, Creel)
