Body: 

The harp assembly was re-installed. Performed a visual inspection of the harp wires after vacuum was pumped back down, the fork wires are still intact.

Body: 

I urge that ILM0R03 be moved ~5m upstream, just after the MBL0R02 it is nominally protecting, as the beam will go into the tunnel wall behind the beam line if the power supply or magnet fails. This will also put it about 2m upstream of the stack of dumplettes rather than 2m downstream.

South Access/Linac - Check/replace LED indicator at the SA fire door (2 hr +/-)

BSY - Replace PSS magenta beacon for BSY in Hall C transport tunnel (2 hr +/-) . MPS documentation checks (1hr +/-).

Injector - MPS documentation checks.

Harp has been replaced and Vacuum group has started to pump down beamline between VBV3H04 and VBV3H07. Initial leak check looks good. They will pump overnight and final leak check tomorrow morning.
Ion pumps and cold cathode gauge will be turned on if leak checks are good.
Interlock checks will then be finalized to complete HCO of the Hall C beamline.

In order to finish HCO for the hall dipole strings, halls B and C will need to be placed into Beam Permit. During this HCO the hall dumplettes (IDA2C04 and IDA3C05) will be inserted to prevent beam going to the halls.
