The keensert has been worn out and will be replaced.
The keensert was re-tapped and the block re-installed. New bolts used for TGHT connection (2x). Swagelok T connections shortened (pluged). |

It seems the exhaust line is blocked which caused pressure to build up and eventually forced the exhaust tube off RP2 as RP1 was roughing down the vacuum chamber.
Vacuum group has been notified and will ask plant group to investigate.
Plant group has removed the blockage. Exhaust lines are reconnected to the roughing pumps. |

Friday, December 18, 2015, 11:44, Anders Mjos, , , , , , , Problems/Solutions, IG6 not reading correctly
|
The new controller (XGS-600) installed for IG6 use a different voltage to pressure conversion than the previous models. This causes a discrepancy between values in EPICS and the value displayed on the controller. An e-fault has been submitted.
Friday, December 18, 2015, 14:40: EPICS updated and restarted. |

Edi Dalla Valle from vacuum group replaced the roughing pump TSG:RP1 in the morning. However, the pumping curve showed a leak: see attachment. It was suspected the VCR water line connection between the lid and the base of the target Heat Shield. After venting the chamber found the VCR connection between the lid and the base forgotten finger tight. Tighten it with wrenches and restarted pumping. |

Turned ON the water for the heat shield cooling circuit. Put a lockout padlock on the transformer breaker since Controls work still seems to be underway. |
