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.

8 NL Cool Down Tie-in
-Will purge and tie-in cool down valve
ESR Status
- Hall A:
- Magnets cold, on cold return, controlling properly - Warm flows return to CHL - Lead flows minimal - Target cold (~300W).
- Hall B:K
- Torus at 80K - Warm flows return to CHL - Solenoid scheduled for August delivery - Buffer dewar cool down started
- Hall C:
- All magnets cold, on cold return - Warm flows return to CHL - Return transfer line replacement did not alleviate magnet pressure issue. - Target cold.
