UCx#16 has been removed from TM$ and UCx#17 installed, high current conductors toqued to 130 in lbs.

 

UCx#16 did not show the standard arcing marks on the 9 pin connector.

In regards to the 9 pin connector on number 17, it was by far the best fitting TM4 target with 9 pin as it required no "fiddling" during installation.

Thursday, November 26, 2015, 09:55: PS energized. EE connected to power supply.

Thursday, November 26, 2015, 11:41: Applied some current and voltage to all power supplies. All looks good.

Some sparking around 5 kV. Turned out to be a bad cable connection. Fixed with David W.

Thursday, November 26, 2015, 15:04: BIAS/EL/EE 20 / 15 1.5 kV

Thursday, November 26, 2015, 15:43: Handed TCS over to ISAC operations


 Target heated over the weekend. EE went into current limiting (down to ~100 V) a while after the target was at temperature.


Monday, November 30, 2015

Target conditioned by ISAC operators to 30 kV without any problems.

EE current limit increased to about 26 mA in an attempt to recover. Cooling down target to investigate.
