| 6640 | 5/18/2017 10:33 | Opening GV 1,2 isolating vertex from x & y beam manifolds. The manifold turbos are ON and open to beam tubes. IP 5,6 are valved out. Pumped out gate annuli on both valves. This will allow access to oplevs/pcal camera to help with ITMx alignment and/or imaging. It could also speed up pump down time. | |
| 6639 | 5/17/2017 10:33 | Update and restart the Beckhoff PLC code on h0vacmr to match the IP6 controller change from a dualvac to a gamma. Due to the difference in the signals for the controllers, some EPICS channels will be lost and others added. Minute trend files may be renamed. Requires a DAC restart. Will update autoBurt.req file and MEDM screens. Will coordinate with the vacuum group. | 36259, 36266 |

This should be done when users are not in the middle of large measurements in case we impact h1nds1 again. | |
