|
The back half of the water block jig (services tray side) has been sucessfully located onto the module.
About 50% of the waterblocks have centered themselfs it their respective cups and the rest look good for concentricity but will require some gentle
wiggling to get them to seat. |

It was found that the conversion from voltage to vacuum (Torr) in EPICS is not correct for the XGS-600 controllers in use at the TCS. EPICS did
not correspond to local values displayed on the controller. An e-fault has been submitted. |

Bevan attempted to start pumping down on TM4 today remotely but there was an issue. He will report on Monday.
I went into the Target Hall this afternoon while on the phone with Bevan and performed the following:
- Checked the knurled vent valves on the side of each turbo, both were found to be in the tightened position (all the way clockwise) |
