2/16 Update
- CHL:
1 Replacement/upgrade of LN2 fill station gauging: -Materials: On-site -Pressure System: Standard Maintenance -Drawings: N/A -Fabrication: N/A -Operations: Assigned Tank 2 complete. Tank 1 is being prioritized. -Testing: Snoop upon installation.
2 CHL Guard Vacuum -Materials: installed -Pressure System: Signed -Drawings: Complete -Fabrication: N/A -Operations: Will test run upon completion of electrical and IA installation. -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 CHL Recovery Purifier Sieve replacement -Materials: on-site -Pressure System: N/A -Drawings: N/A -Fabrication: N/A -Operations: P5 sieve replaced and ready for use. -Testing: N/A
6 ESR ORS Carbon Replacement -Materials: Lifting adapter approved by Sprouse. Estimating ~$350 for materials -Pressure System: N/A -Drawings: Need to be developed. -Fabrication: awaiting drawings -Operations: Needs to be scheduled/planned. Probably next summer -Testing: Spool pieces will need to be tested.
7 ESR 15K U-tube -Materials: ordered -Pressure System: signed -Drawings: issued. -Fabrication: in fabrication (expect to test by 3/3/17) -Operations: U-tube will be stabbed at earliest convenience (when it will not impact target schedule) -Testing: pressure test per DPF
8 ESR Oil collection -Materials: TBD -Pressure System: TBD -Drawings: TBD -Fabrication: TBD -Operations: May require piping removal or plant shutdown -Testing: not likely. category D piping at most.
9 CHL IA modification -Materials: ordered -Pressure System: TBD -Drawings: in development -Fabrication: TBD -Operations: N/A -Testing: Initial service leak test
10 CHL purifier sieve heater -The improved methods for regenerating the sieve beds to be performing sufficiently well that a new design is not necessary. The design criteria has been saved in the purifier pressure system folder.
ESR Status
- Hall A:
- Magnets cold, on cold return, controlling properly - Warm flows return to ESR - Target cool down scheduled 2/16/17
- Hall B:
- Torus cold, on cold return, controlling properly - Warm flows return to ESR - Solenoid scheduled for May delivery
- Hall C:
- All magnets cold, on cold return - Warm flows return to CHL - SHMS magnet pressure at 1.7 atm, anaconda replacement plans being made - Q3 and dipole testing underway. - Initial target cool down (~1 day) scheduled for 2/20 - KPP scheduled for March
