Agenda and Notes

1. Safety

2. Schedule

• Near term schedule Media:img_3327.jpg

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

CTF restarted.

ESR normal. Hall C continues to SLOWLY cool down. The high magnet pressures on the SHMS are still an issue.

CHL1 at 4K

CHL2 is off to support C6 work.

CHL Recovery: Purifier 5 carbon has been replaced. pump and backfills on-going. After purifier 5 is online and operating acceptably, carbon will be replaced in bed #4.

HDR Normal

4. JLAB Internal Group Projects

CHL1 SC1 CC5

Final utubes for disconnecting SC1 are to be done Wed and Thur.

Air Liquide is expecting to have technician here on site first or second week of May.

Decisions need to be made regarding the flanging/sealing of the CC.

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..

Anticipate problems with the controls during the cooldown.

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)

C6 installation work has started. Mechanics are working now. Electrical should start by the end of the week. We are expecting about 5 more weeks of work to complete installation then commissioning will start.

JLAB Guard Vac (Schleeper, Radovic)

-Legs are being cut and prepped for anchor/grout. DONE! -Taps need to be added to the pump suction. (fab) IP -remove/route the conduit (Electrical) -remove railing (ops) -Instrument Air line (fab) -final assembly of pump/filters (ops) -controls (electrical)

CHL LN2 Dewar Fill Transfer line (Schleeper)

-process improvements being tested -vacuum needs to be pumped -relief valve needs to be replaced/ordered (will set up a meeting)

JLAB 3rd Recovery Compressor (Saringer)

The skid is complete.

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 Fill Relief Replacement (Schleeper, Thompson) Replacing existing relief valve. Evaluate fill process to prevent lifting the relief.

CHL LN2 Dewar Instrumentation Replacement (Schleeper, Thompson) causing errors in the pressure gauge on fill station.

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

ESR Carbon Replacement (Schleeper, Butler)

ESR Oil Containment (Schleeper, Thompson), working. Paused to support C6 work.

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 12 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 some concern that moisture may still exist within the cool down piping in the north linac. The goal is to have a hygrometer added to the recovery system so that when a purge flow is added, moisture can be monitored. After the cool down piping has been purged (duration TBD), we will re-connect the cool down line at the conflats.

SRF is planning to replace cold windows on 15 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'. (Issac) We are building a guard vac skid for LCLS2. Not started. Due end of October 17'(Issac). 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.
