3/15 Update
- CHL:
1 Replacement/upgrade of LN2 fill station gauging: -Gauges have been replaced but the Dewar #1 Gauge is reading incorrectly. Working to repair.
2 CHL Guard Vacuum -Materials: installed -Pressure System: Signed -Drawings: Complete -Fabrication: Removal/repair of the hand rail. Grouting and leg re-work. -Operations: Will need to remove feet, grout, shim and anchor the feet. Will require welding. -Testing: To be initial service leak checked upon completion of electrical work. Pump temperatures will also need to be monitored.
3 LN2 Dewar #1 instrumentation tubing replacement -Materials: On-site -Pressure System: Signed -Drawings: Complete -Fabrication: All paperwork and materials are with Scott. He is scheduling. -Operations: N/A -Testing: To be initial service leak checked upon completion.
4 LN2 PBC leaks -Materials: TBD -Pressure System: TBD -Drawings: TBD -Fabrication: TBD -Operations: All leaks have been identified and tabulated. Ops is investigating the repair of threaded connections. -Testing: Snoop
5 ESR ORS Carbon Replacement -Materials: Lifting adapter approved by Sprouse. Estimating ~$350 for materials -Pressure System: N/A -Drawings: Need to be developed. Sent to Corey for him to prioritize. -Fabrication: awaiting drawings -Operations: Needs to be scheduled/planned. Probably next summer -Testing: Spool pieces will need to be tested.
6 ESR Oil collection -Materials: Ordered, waiting on sight glass to arrive. -Pressure System: N/A -Drawings: Sketch delivered to shop. -Fabrication: TBD -Operations: Will require familiarity with system prior to installation. -Testing: N/A, down stream of relief.
7 CHL IA modification -Materials: ordered -Pressure System: Cat D -Drawings: in development -Fabrication: TBD -Operations: N/A -Testing: Initial service leak test
8 NL Cool Down Tie-in -Will purge and tie-in cool down valve
ESR Status
