sPHENIX discussion of the superconducting solenoid

[Kin Yip <kinyip AT bnl.gov>]

Hi Roberto,

Thank you very much for the status report.   I've also talked with Rich (who worked with Brian to solve at least one problem so that valve can be opened)
and Pat this morning ... and then you this afternoon.   Hopefully, we don't need Brian to debug anything any more :-) 

Looking forward to being able to finally cool down ...

We put the Turbo A and roughing A back to continue pumping on insulating vacuum. “A” side is all manual with no vacuum valves to interlock between turbo and roughing.

 

Need to do some more rewiring to move the relays for the vacuum pumps contactor to the contactor box.

The draw was 4 amps, but we limited by the cable size. Instead of running thicker wire, we are moving the relay upstairs, and run just the larger wire inside the contactor box.

 

B side we will retest after wiring fix.

 

Pat said he will upload operator interface by end of day.

 

He took V days to take the kids to Pennsylvania.
