2/16 Update Organize cryo pressure systems
- 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 -Materials: Awaiting design -Pressure System: Awaiting design -Drawings: Awaiting basic design -Fabrication: Awaiting drawings -Operations: TBD -Testing: Test per B31.3, with consideration for temperature requirements.
ESR Status
- Halls A, B, and C are on cold return. Hall C magnets filling.
- Hall C is cooling SHMS Dipole to 100K. U-tubes were stabbed Tuesday.
- Hall C target system is being cleaned. Not connected to ESR or recovery as of now.
- CHL-ESR x-fer line will be in use occasionally over the next week.
- T2 will need to be stopped to facilitate simple trouble shooting on inlet valve/actuator.
MSU FRIB
Organize and publish pressure system documentation for pressure systems. Actions are as listed in the summary document.
- IA complete
- GV complete
- LND complete
- waiting for examination docs from embler.
