>From the MCC meeting this morning:
--> North Linac restoration went well, the South Linac still need some work. All eyes on the NL aperture (obstruction) test by the end of the day shift.
--> the NL Vacuum seems to be good so far. The vacuum leak issue (caused the downtime a few weeks ago) has not been observed.

Hall C update:
--> Most of the systems remain shut. Normal gas flow to the DC was restored yesterday, and will be ready for operation by noon.
--> The newly install HMS and SHMS motors were installed and tested. Joe had to by-pass the brake in order to make the new motors work (due to the lack of voltage).  We will be rotating the spectrometers with no brakes (less accuracy in the last few mm). The brake issue will be fixed next week.
--> Beam permit check list  is on-going.
--> Based on the update from Wed 1:30pm meeting,  a decision will be made regarding the target ladder cool down .
--> Hall lock down is expected by the end of the day-shift Thursday (4pm, Sep/20th).
--> Shifts remain canceled until 8am, Sep/21th (Friday).
--> We will not have a RC meeting today.

Planned work:
--> A cosmic ray test is planned for this (Sep/18) afternoon.
