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.

MSU FRIB

Organize and publish pressure system documentation for pressure systems. Actions are as listed in the summary document.

1. IA complete
2. GV complete
3. LND complete
4. waiting for examination docs from embler.
