We have completed all magnet work @1L26 warm region girder and all magnets and components carted and staged. Made LCW lines to keep all LCW up and functional in this region, to ensure Frank and companies turbos and related vacuum remain in line with LCW on.

Will begin work @1L27/NL on Tuesday.

Body: 

Plan for vacuum system when we are done processing 1L07. I discussed the path forward next week with Frank H. Once we get things back on ion pumps we will close the valves on VIP1L07B and VIP1L08A. The beam line valve VBV1L07B will remain open. We will leave the plasma turbo cart on and pumping the vacuum manifold out to the closed valve on VIP1L07B. Frank will then be able to close the gate valve between the beam line and the getter pump on VIP1L07B and reactivate the getter pump while the beam line is being pumped by VIP1L08A ion pump.

Current plan is to start with one array (i.e. 9 dipoles) in the East Arc the week of 10/5 after the BSYSB. Then, would move to the West Arc 7x ZAs.

Be sure the PTW is on-issue for the relevant work before proceeding.
