Agenda and Notes
This meeting is to discuss the ESR capacity usage by the Halls.
1. ESR History
Plant originally built in 1978 for the LBL ESCAR Project. It operated < 900 hours before being shutdown.
Plant was moved to JLAB and installed in 1994 JLAB to support Hall's A, B, and C. The plant has been in nearly continuous operation for 22 years.
2. ESR Capacity
Plant capacity envelope (1500W at 4.5K) OR (800W at 4.5K PLUS 1200W at 15K)
Additional TRANSIENT capacity available from CHL via transferline of up to 20g/s at 4.5K
A general thumb rules, ESR loses 1 Watt of 4K Refrigeration for every 3 watts of 20K refrigeration. Also, 1 g/s of liquefaction costs 150 Watts of 4K Refrigeration.
3. ESR2 Upgrade
Cryogenics group has been pushing the installation of the ESR2 4KW at 4.5K SSC plant for more than 15 years. The building was constructed and the cold box placed inside it but the real work of designing, installing, and commissioning keeps getting bumped because of funding. This is a multi year effort to complete this work.
4. Plan Forward
At this time the ESR is operating above capacity. If the transferline is shutdown the dewar level falls. The CHL1 is supplying about 10g/s to ESR at this time. The transferline will not be available for this summer.
Hall B has submitted the KPP data to DOE for approval. Approval comes in a couple of days and then we would park the Torus at 80K. Paul says HMS might be able to park at 80K for the summer.Hall C warm return will be routed to CHL. Hall B warm return will be routed to CHL.
Action Items
1. Finish the ESR2 design, fabrication, and commissioning ... quickly.
2. Kashy will provide lead flow values.
3. Cryo will revisit the capacity matrix predictor and bounce it against the wants of the Hall's.
4. Kashy recommended a test before the end of the run to see where the actual loads are with respect to ESR/CHL capability. This could happen as early as next week.
5. Brindza indicates Hall C is having a serious pressure drop issues on the cold return for the SHMS system. Possibilities are its because of the flow and pipe size, it could be a valve that is not full open, it could be a partial plug in their lines.
