sPHENIX discussion of the superconducting solenoid

[Kin Yip <kinyip AT bnl.gov>]

1. Roberto has expected that we'll do the pressure test/leak check 
tomorrow (Thursday, Feb. 4, 2016).

2. Dave Phillips has got the technicians to anchor the power supply/DAQ 
racks properly.   But he doesn't like
    the rubber "barrier" that his technicians have placed around the 
power-lead in the valve box.  Because it's
    not electrical-rated.  He's ordering/getting one.  In the meantime, 
I went to Mel VanEssendeft and asked
    him to write in the work-permit that it's enough to disallow people 
from going up the platform.   So that we
    can proceed to hypot test without finishing this item of the 
ASSRC/ESRC checkoff list.

3. If the Cryo group can finish the pressure test on Thursday, 
Piyush/Sonny will do the hypot/impulse test on Friday.

4. They'll do the 2nd welding for the pipeline cut away from the ERL 
system today and this would finish this cutting/welding
    business.

5. DAQ is basically ready.   Piyush can turn on the DAQ logging system 
on Monday, possibly at the rate of every 10 minutes.

6. Achim has installed the physical Hall probe system inside the 
Solenoid.  It's understood that he plans to measure the field
   at the beginning of each current ramp (100 A) and at the end of each 
ramp.

7.  In principle, everything is ready next week except Pat Talty (Cryo 
group), the software engineer, setting up/testing the
     controlled cool-down.   Apparently, he's the only person who can 
do the job and CeC wants to cool down as soon as possible
     and he's still working in CeC.   We're also try to cool-down and 
do our test as soon as possible.
     Optimistically, Pat may come to help us on Wed. and very 
optimistically,  we may start cooling down on Feb. 12.

[  Addendum:

8.  We have had the ASSRC/ESRC safety walkthrough at 2:30 pm after our 
meeting.  There is no real major item that I can remember.
     We'll get a list of a few reminders (vaguely remembering that we 
have to administratively coordinate with the ATF II for the crane
     movement during our test ... doing the final Magnet Review by 
Jesse Fite just before the low-power test). ]
