ESR Status

-Halls A and C are cold and on cold return. -Hall C has been performing heat leak testing of the SHMS Q2. Expected to carry into week of 1/22. -Hall B is cooling solenoid. Expected to be on cold return 1/20/2017. -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.
