Subject: [Esr-users] Hall A transformer problem as potential ESR transient


Hello to All,

During middle of Saturday morning 15 August 2020, Hall A called the ESR Engineer. Hall A is having a transformer problem. There is a concern that Hall A magnets may dump. The abruptness of large increase in helium return flow from Hall A would be an operational transient for ESR and CHL recovery system.

Thanks!
