Due to high vacuum a leak check will be done on the system.
Thursday, July 19, 2012, 09:00 : Base leak rate 4E-9 atm-cc/sec
Thursday, July 19, 2012, 09:07: Leak detected on side door. Mid 1E-8 range.
Thursday, July 19, 2012, 09:08: Leak detected on front door. Mid 1E-6 range. Main leak left or bottom side.
Thursday, July 19, 2012, 09:20: Leak on side door could not be reproduced. Previous response possibly due to "cross-talk" with front door.

A major leak was found on the connection to the regulation valve on the He bottle. Ferrule replaced. System leak checked.
After He bottle: base 5E-6, no response to He spray
AfterSV1: base 5E-7, no response
After SV2: base 4E-7, no response
The system should now be operational. Gas lines were evacuated with the leak checker. |

There was a short between the gas line and the heat shield - as the gas line insulator was not tied to the heat shield. A Ta-wire was used to tie the gas line and keep it from touching the heat shield. |

The fuse for both roughing pumps blows when roughing the chamber. With the help from Edi: disconnect the exhaust port on the roughing pump for the first few hundred torrs of roughing. Reconnect and continue.
Seems the roughing pump RP1 pushes air towards the exhaust of RP2 which blows the fuse |
