sPHENIX discussion of the superconducting solenoid

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

Hi,

No. Because this is a substation and transformer for 1008B and C,  a different substation of  1008-IR and 1008A .

But PK Feng has doubt about the reverse ...which is under discussion.

    Hi Kin,
     Will there be a brief power interrupt when the phase is reversed?
    If so will that affect anything in 1008, like PASS? Thanks.

Pablo,

 

Larry just talked with me and the line crew will go to the sub-station after lunch to reverse the phases for 1008C so that

1008C may circulate water to our Power Supply/Water-cooled-bus ☹ 😊

 

( One sometimes feels that everything can go wrong has gone wrong 😅 ) 

 

Staying positive 😊

The whole feed from the sub-yard has reversed phases,  this has to be addressed today.
