[Esr-users] ESR Configuration change

[Qiuli Sun]

Dear Rob and Dave,

We plan to run our HB magnet today. We would like to open this afternoon during our magnet test its warm return to lower its pressure and therefore its temperature.  

Is it okay with you?

Thanks a lot

Eric

Please send these emails to 'esr-users at jlab.org' in the future.

I Believe we should be able to support that this afternoon.


Hall B Return is presently configured to CHL Recovery.
