sPHENIX discussion of the superconducting solenoid

[Kin Yip <kinyip AT bnl.gov>]

We've had the shortest meeting ever : essentially we finished our meeting at 1:45 pm today.

1. Roberto told us (and I actually just went to Bldg. 912 and saw) that Rich Meier/L. Masi Jr. are NOW replacing the two BaBar/SLAC
   flow controllers with the flow controllers that BNL has always used and we're familiar with.   Once the new flow controllers are
   physically installed in the piping, Roberto can get rid of air, and then pump and purge.   He'll then start cooling-down tomorrow (Feb. 25).  
   The electrical wiring and power supply (which we're ordered and should come overnight) for the flow controllers can be finished during cool-down.
  
   The shield flow controller needs to be verified also for operation.  But these are the BNL flow controllers, not SLAC ones.

2.  Achim Franz is testing (as I write this) his magnetic field testing probes ... He's still not heard from D. Phillips where his data acquistion tray/table
    can be placed.  He'll go to find Dave to figure it out.    He just needs two 110 V outlets.  Right now, he's just used the outlets close to the Magnet.

3.  Since the positioners have been burnt out, Roberto's buying 6 positioners (we need 5) using sPHENIX money (~$10K) which will be used for
    the high-field test and the future sPHENIX in Bldg. 1008.

     Not very exciting yet ....  }
