[dsg-halla_solid] Findings on magnet voltage tap connectors

[Steven Lassiter]

Talked with Whit and the sorb wiring on the B connectors are for temp sensors.
Therefore they should be wired to the B connectors on the vacuum side and we can check for continuity once the turret is installed.
We are not planning on using the sorb heaters (2 heaters of 10W and 33.0 ohms) for the low current testing, but they do offer two additional temp sensors of the coil through these wires.
The cabling for the sorb temp sensors should be a different cable from the pot taps if they are wired.

I would suggest wiring a short extension to the temp sensors air side B  connectors that could be connected at a later time if desired.

It is not planned to use them for the low current testing
Maybe Whit should comment on this

Hello Steven,

Brian and I just double checked the pinout for the connectors at the turret flanges, connectors B1, B2 and B3 to make sure that we have the correct wiring for the voltage taps.

Based on the Oxford drawings, we found that besides of the the voltage taps wires, there are wires in B1, B2 and B3 connectors that goes to the sorb heaters and magnet shell heater (total of 6 wires: 2 wires for each sorb heater and another 2 wires for the shell heater).

Will these heaters be used/wired?
By looking at the Controls-CLEO spreadsheet, I can see that at some point two relay channels were assigned for the sorb heaters but we do not have any drawing or cable planed to be used for these heaters.
We need to know this before starting the fabrication of the voltage tap cable.
