[dsg-halla_solid] SoLID Magnet Controls updates

[Steven Lassiter]

Hi Pablo,

Mods to the PLC and HMI may be needed as the testing is carried out. One thing that might be added are specific temperature comparisons on the LN2 shield for cool down.

The schedule for the CLEO_II testing is currently as such:
Assemble magnet and do testing on vacuum, pressure testing, electrical testing, controls, and purge system:   finish by 11/29
Sting U-tubes : 1 day 11/29
Cool down with HX to 80K:  14 days finish by 12/15
Cool down to 4.2K with He: 5 days finish by 12/20
Cleo II low power test: 2 days finish by 12/21
Warmup to 300K: many days
CTL shutdown for maintenance Hard date 12.21.22 at 8am

Thanks
Steven

Hello,

Most of the PLC programming and HMI screens are done.
Waiting on solution from vendor (EECCO) of software that will be needed to transfer data between PLC and EPICS, if solution does not work, then we will implement EPICS sofIOC to transfer data between PLC and EPICS (same as other Halls).
The cable needed for the readout of the voltage taps from the magnet to the resistor box and the cable to readout signals from the power supply are being fabricated.

At this time, DSG doesn't know the date for the low current test.
For now DSG is focusing on the assigned tasks for the NPS project, but support to accomplish the with low current test of magnet will be provided as needed.
