Hi,

The Magnet quenched at 6:58 pm.  Rich (CAS) and went up to 1008B to check and it seems that the first one was due to "Crowbar Temperature Sensor".  I attach a picture of it.

The quench detector was triggered by "Coil Difference" which (to us) is more likely a consequence.  I also took a picture of it.

Too bad.  Rich and I think that we have to wait for Pablo to take a look tomorrow ... 😐

No more shift tonight and no shift for John Haggerty.

Kin
