Thursday, November 07, 2019, 10:35: Tested source to 30 A on TGHT, TBHT and COIL. ANODE at 100 V.
Tuesday, November 12, 2019
The FEBIAD source worked well over the weekend. The anode current limit was adjusted twice to stop voltage limiting. About 5E-8 A on the FC with TGHT=580A, TBHT=300A, ANODE=200V,150 mA, COIL=50A. Bias was conditioned to 30 kV |

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. |

Sic#35 has been installed onto TM2. High current fasteners torqued to 130 in lbs.
Mating of the 9 pin connector was extremely problematic but in the end I was able to get it to mate properly. Noticed left (when facing module in hot cell) febiad coil left twisted a bit when torqued up. |
