Friday, September 23, 2011, 16:3: The connection on the 9-pin connector for FEBIAD targets showed burn marks from the previous FEBIAD tests. Corresponding mark was found on the connector on the target side. Because of this the upper and lower 9-pin connectors were swapped to have a clean connector for the next FEBIAD target.

• While testing SiC#26 a leak was discovered on the water line to the heat shield. The leak was in the right joint (see attachment). The heat shield water lines were removed from the test stand and repaired in the Machine Shop. 
• Kapton was added to the FEBIAD coil line to prevent it from shorting to the target heater line (see attachment).

Variable leak valve with serial number F3-592 has been replaced by F3-649 due to regulating problems described previously by Fridhelm Ames.

 The variable leak valve F3-592 has been repaired. Contaminated diaphragm was replaced. See attachment for details.

Evgeniy rebooted the ISAC Test Stand IOC. Re-started EPICS at the Test Stand.

Found all 4 turbo pumps off and their backing valves closed. Re-started the pumps.

In January Controls will install a new firewall for ISAC Test Stand. Until then ISAC Test Stand can be used, but it may require an IOC reboot once in while.

 The leak valve has been tested with He and a leak detector. The leak valve could regulate in the complete range of the leak detector. 10^-11 to 10^-4 atm cc/s

turbo pumps shut off due to work on cooling water system

All turbo pumps have been restarted after cooling water is back and running.

Both turbo pumps at the source box were found off. TSG:TP1A has been started normally. TSG:TP1B does not spin up above 3KRPM even after several attemps. A fault report has been send to vacuum group.

 after about 30 minutes running at normal speed TP1A failed as well. Both pumps will be kept off over night.

New supply of He and Ne was installed yesterday and gas lines leak checked. The He bottle is currently closed.

Specifications for the currently installed Ne leak (SN: 11-231) can be found on DocuShare
