ESR Status

1. Halls A, B, and C are on cold return. Hall C magnets filling.
2. Hall C is cooling SHMS Dipole to 100K. U-tubes were stabbed Tuesday.
3. Hall C target system is being cleaned. Not connected to ESR or recovery as of now.
4. CHL-ESR x-fer line will be in use occasionally over the next week.
5. T2 will need to be stopped to facilitate simple trouble shooting on inlet valve/actuator.
