sPHENIX discussion of the superconducting solenoid

["Yip, Kin" <kinyip AT bnl.gov>]

Hi,

 

I attach the latest screenshot of the Cryo HMI and you can see that the temperature sensors seem to be between 255-260 K.  The cool-down rate is

slightly faster than 0.6 K per hour.

 

--- Pablo Rosas is trying to finish his power supply test.   The last part should be the short-circuit (which he’s probably already started to set it up …

    I didn’t manage to catch him this late afternoon. )  

 

--- Frank Toldo/Paul Giannotti have connected all the strain gauge/linear pot cables and it seems that Frank just needs to finish all the termination

     tomorrow.

 

--- One of the strain gauge J cable has a deformed plug and Richard Meier has agreed to fix it, as he dealt with it before J 

 

--- Zeynep has moved her $40K PXIe in the 912 quench-detector Rack.  Frank has also helped provide us with power strip with long-enough cord.
