[dsg-hallb_svt] CVT work

[Brian Eng]

The iseg HV card to patch panel cable can't be fixed (at least not quickly and we don't have the parts) so I replaced it with a spare cable.

Both of the HV patch panel to detector cables that had pins pushed in were fixed. However, the pin on the R1M10 on the front of the patch panel is damaged and it looks like there's debris in it as well. The quickest fix would be to just use the next connector down, but I don't know how easy that change is to make in software. Maybe using the old R4 HV patch panel box instead?

The slow control cables between the VME crate and patch panel were connected and the coolant temperature sensor cable to the patch panel was repaired (but I couldn't find a heat gun for the heat shrink so it temporarily has tape on it too).

Networking was run for the slow controls VME crate, the DAQ crate that has both the controller and power supply (the other is missing both), and all the MPOD modules.

I started to run cabling for the HTSB sensors in the detector but there is still some coolant lines that need to be insulated and/or connected so I didn't want to undo the HFCB disconnects that have been folded back. The insulation needs to be repaired prior to connecting any of the detector cables since once the structure that holds the L1C is installed that part will be very difficult to access.

No, #5, the strain relief needs to be fixed. Also, in the male 5-pin HV cables which plug on the front side of the HV distribution box, there are connectors with 1 pin pushed inside the connector. We leave them unplugged. The SVT has been mounted on the support tube. When DSG could provide support to route and connect the SVT cables? We are talking about the detector side of the cables and the crate side slow controls. Rafayel and I are connecting the HV, LV, and VXS on the crate side now. Thank you

I assume you're talking about #7?

If so, hopefully the friction of the pins will be enough to hold it in.

If not, you might need to take one of the ones from the test stand in the cleanroom and replace it, for sure we don't have replacement parts for that connector.
