[Esr-users] fast dump test of Hall C SHMS HB magnet

[Qiuli Sun]

Dave,

We plan to do it at between 2:00 PM and 3:00 PM. The purpose is make sure our HB magnet is fine after the incident we observed in our last training (3206 A).

Thanks a lot

Eric

Dave,

Mike Fowler and I plan to fast dump our SHMS HB magnet from 3000 A. The HB magnet has only 0.11 MJ stored energy at the current. We don't expect this will create disturbance to the cryogenic system per our past experience.

If you have concerns, please let us know.

Thanks a lot

Eric
