|
Between feedthroughs F (magnet coil) and B (tube heater negative), I found a jumper with two resistors that has been burned up. I am not sure when this
happened, but it would be good to review the overall setup of the service cap wiring in the new year.
The cable connected to feedthrough Q where the multipin sits also looks burned. |

The copper tubes to be used in the TM3 test piece may have flux inside them from soldering the end caps on. There are holes along the length for outgassing,
and we will try to bake them out in the test stand before installing them. There is still a dummy bake out target installed there, see the photo for how
the tubes are loaded in. TGHT ramping started around 3pm. |
