sPHENIX discussion of the superconducting solenoid

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

Hi,

We are using (or trying to use) the SLAC/sPHENIX power supply right now.  A voltage tap seems to be open today and Carl and Zeynep are changing to another tap ...

    Hi Kin,
     What is the status of the hook-up to the SLAC magnet PS?
    Thanks.

Hello,

 

I am just attaching a Cryo HMI temperature graph when MT01 ~ 4.5K.   The temperatures there are probably as good as it’s.

Today is the first time that we’re using interlocks (something new today !).   Paul Orfin is now adjusting temperature thresholds

to let us run --- this is something you need to do to deal with the realities

 

Zeynep is going to turn on the quench detector so that the other interlocks can be cleared.
