ESR Status

1. Halls A, B, and C are cold and on cold return.
2. Hall C is cooling SHMS Q3 to 100K. U-tubes were stabbed Tuesday.
3. Hall C will stab dipole u-tubes next week.
4. Hall C target system is being cleaned. Not connected to ESR or recovery as of now.
5. CHL-ESR x-fer line will be in use occasionally over the next week.
6. T2 was warmed with no clear benefit. Developing actions to remedy the situation
