For Door 1 and Door 2 in both of these segments, the lock readback seems to be faulty (Fig. 1). When unlocked (signified by un-illuminated door release buttons)(Fig. 2), iFix shows Door 2 as locked and Door 1 as unlocked. The 'Arm' readbacks seem fine.

Body: 

Final alignment of MYBBS06 is complete. The positions of three flanges downstream of the magnet (starting at the DS end) are listed below. The large offset likely results from the 1.5° pitch of the DS chamber flange. The beampipe ID in this section is ~38 mm, but the 8.4 mm height of the gate valve flange limits the clear aperture to ~8 mm. The beam pipe upstream of the bellows is not adjustable.

Removed valve open position jumper for VBV2H01A and plugged the valve cable into the vacuum controls.
Removed valve open position jumper for VFV2H01A, but left the valve cable disconnected to until beamline is fully put back together.
Removed simulator box for VPG2H01A and plugged it into the convectron gauge on the beamline.
Plugged in the HV cable for VCG2H01A and turned the cold cathode on.
Work is in preparation for the beamline to be put back together and pumped down tomorrow.
