RULES: No arguing. Everyone will be heard.

Attendance

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


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


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

CTF Shutdown nearing completion.

ESR normal. Hall C continues working on perceived plug.

CHL1 at 4K

CHL2 at 4K

HDR Normal


4. JLAB Internal Group Projects

UIM (Wijeratne, Wright, Creel)

Calendar

The shutdown is scheduled from 17 Feb - 9 Apr (Dewar Full). We are in clean up mode anticipating restart around Thursday..


GPP (Yang, Wright)

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.

Kelly contacted the HAWKINS-HAMILTON for potential liquid ring pump replacement. The vendor proposed the NASH 2BE4 32 vacuum pump. We can adjust our current laytout for this potential replacement. But it seems that our inlet pressure is far out of the pump performance curve. Shirley is going to check with the vendor - UPDATE: NASH AT3006 with a minimum inlet pressure of 1 in Hg abs was recommended by vendor.

Reviewed the 35% concept plan for the gas management. Thilan is working on the regulator valve for the recovery mass-out valve. Need to know if the main compressor bypass valve can be sized for only running the two compressors at the same time.

Gas management tie-ins were finished.

35% of gas management concept plan was reviewed on Mar. 2, 2017. Several issues were discussed:

1. The maximum air pressure for both Fisher and Badger control valve regulators were confirmed. 2. Robert / Jonathan and Mat are going to look options for new pressure transducers for the new gas management skid. The local tabs are required. 3. Robert is going to look how to run tubing and conduit. 4. Need to determine (Thilan, Mat and Shirley?)if the flow meter needs to be installed on the skid. 5. Thilan is going to check the cooling water header to make sure it is sized properly.


CHL2 C6 (Perry, Creel)

The C6 installation work will start soon. The conduit and wiring installation work will begin the week of April 3. The mechanical work will begin the week of April 10. The mechanical work should take about 6 weeks. Commissioning and testing should take place around the week of May 29.


JLAB Guard Vac (Schleeper, Radovic)

-Grouting will be added to the feet/legs of the skid. The legs will need to be shorten to support this. (ops) -Taps need to be added to the pump suction. (fab) -remove/route the conduit (Electrical) -remove railing (ops) -Instrument Air line (fab) -final assembly of pump/filters (ops) -controls (electrical)


JLAB 3rd Recovery Compressor (Saringer, Creel)

The skid is complete except for one pressure gauge which is on order.


JLAB recovery header rework (Saringer, Wright)

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


JLAB Vaporizer (Perry, Wright)

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.


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.


CHL LN2 Dewar Instrumentation Replacement (Schleeper, Thompson)

CHL LN2 Pressure Building Coil leaks (Schleeper, Thompson, Hunewill)

ESR Carbon Replacement (Schleeper, Butler)

ESR Oil Containment (Schleeper, Thompson)

CHL1 Regeneration Skid Removal (Schleeper, Thompson)



5. 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. Solenoid is expected in May.


UITF (Perry, Radovic)

Thermosiphon and utubes are being fabricated. The electrical controls work will start after the UIM CTF & C6 are finished.


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.


NL cooldown header re-connection (Schleeper, Wright)

There is a purge plan, will be performed AFTER CHL u-tube operations. Re-connection will happen thereafter.


SRF is planning to replace cold windows on 13 modules


6. JLAB External Projects

MSU (Dixon)

Robert is still working 2K controls.


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.

LCLS2 is indicating we could pick and choose a host of items we could build for them such as 230 bayonets in approximately 6-7 months.
