Dear all,
At 7:10am there were multiple alarms on account of torus and solenoid fast
ramp down. Also there was an ODH alarm in the Hall. Shifters notified
Engineering on call as well as magnet experts. After online diagnostics,
shortly after 9am Calvin, Brian, Denny and Ruben came to counting house.
They collected log data for diagnostics, reset torus PLC and are working
to recover magnetic fields. Hopefully, we'll have magnets ready before
swing shift.
For Monday morning, MCC is going to take beam away around 8:30 and switch
to 3-pass. We are planning to use this time to access the Hall (only
Eugene so far) and for reversing torus polarity.
Best,
Andrey.
