Helium pressure leak check on TM2 HS line at TCS is done. No leak. Also, Helium are sprayed to gas line adapter and fittings. No leak. TM2 is connected at TCS. Anode plug on TCS is connected to module 52pin connector. Water system is started. Vacuum pumping down is good. HV cover will be installed today. |

Friday, October 20, 2017, 14:51: Gelo has determined there is a communication problem with the PLC on the HV platform. Troubleshooting continues.
Friday, October 20, 2017, 19:02: Troubleshooting did not succeed. Not able to control power supplies. Troubleshooting continue on Monday.
Monday, October 23, 2017, 09:00: After starting the TCS again today communication has been reestablished. Started heater conditioning.
Monday, October 23, 2017, 14:03: Heater ramping previously aborted and ramp down started due to ongoing PLC communication issues. TGHT and TBHT power supplies tripped on timeout around 13:45. Gelo will continue the troubleshooting.

TM#4 with SiC#37 has been moved from the conditioning station to the east target station. A measurement was taken on TM#4 as it was being removed from the conditioning station, the location was on the side of the service tray access panel approx one metre away and the cover fully exposed, the reading was 750uSV/hr. |

Thursday, October 26, 2017, 09:56, Anders Mjos, ITE, Repair, TM4, SiC#37, Leak on multi pin connector feedthrough
|
On maintenance day Tuesday, the roughing of the target station could not go below 1.5 Torr. A brief troubleshooting on Tuesday was unsuccessful in determining the cause. Leak checking continued on Wednesday by David and Anders. A leak was finally found on the multi pin connector feedthrough due to the seal between the connector and flange on top of the nylon insulator. Upon re-tightening the connector, the leak could be stopped and the module pumped down to allow starting of turbo pumps. |
