sPHENIX discussion of the superconducting solenoid

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

Hello,

Thanks for solving this temperature mystery !     The CERN team needs to replace a probe or two.  We'll bring down the magnet this Midnight.

We'll open the pole-tip door tomorrow morning (after all the LOTO's).

So, you may reboot again then 🙂

We had to reboot most of the fecs following the NW router change on Tuesday.

It looks like the new scaling was not restored when the fec was rebooted.

I have put it back to what it should be.

When it is convenient I would like to try rebooting that fec again to make sure we don't have a caching issue.

Hi,

On the pet page/Logview, the temperature seemed to rise to 48/49 C (see Log view page attached) since sometime on Monday.  But ( from the water group webpage and) from the PLC screen in front of the power supply, it still said 24/25 C.

Tim told me that you should be reading the same thing as the PLC ...

Do you understand what it's going on ?
