[Dsg-hallb_magnets] Hall B magnets trip

[Brian Eng]

Did the shorting leads for the VT panel of the Torus get installed?

Also, was the QD already reset for the Torus? If not, it is kind of odd that there are no QD faults in the interlocks.

I'm pretty sure this has the same faults when it tripped on 10/10 and we couldn't find anything in the VT data that time either, but maybe this one is different?

The one on 10/10 had nearly all the Torus QDs tripping at the same time and then a Solenoid QD ~400 ms later.

I made a logbook entry with some screenshots: https://logbooks.jlab.org/entry/4232495

Probir, You're completely right.

I misread the columns I guess.

I disagree...I see that that Torus Sum2 ent earlier than solenoid...!
Please confirm..

Hi Probir,

The SOE screen for the Hall B magnets show that Solenoid QD2 tripped first. Photo of screen attached.

I'm currently pulling up the VT archived data to see if there's any more info there.
