Dear Collaborators,

As you all know, last Friday we had a major failure of the solenoid. The power supply was badly damaged and needs repairs. We also assessing if the magnet itself is not damaged as a result of this event. The investigation is ongoing. We are also investigating what was the root cause of this incident. All monitoring data were sent to Danfysik, the company which built this power supply. It is important to understand what went wrong in the power supply because we use exactly identical power supply for the torus. We need more time to fully assess all damages and then depending on findings understand how much time will be needed to bring the solenoid back to life.
Meanwhile, it is clear that it will not not happen before the year end. As of now all shifts are canceled until mid January.

We will send an update as soon as we have any new information.

Stay tuned.
