[Esr-users] Full Load Test of ESR, Halls A, B, C with magnets and Targets

Hi All,
In the interest of having a successful run in December, I would like to hear your opinion of running everything needed for the December run next week.
Hall B already has a plan to run both the Torus and Solenoid on Friday 11/17.
I know that the Hall A target can't be run before Dec 3 or 4 because of safety rules that have been written and approved.
We would need all magnets at full field with full field lead flow and a target to simulate the 15K load on the ESR

The questions are:

1) Is this a good idea?
2) Can all the Halls ramp their magnets to full current starting early Friday morning and have them to full current by 11:00 or noon?
3) Can the target group run the Hall C target to nominal operating power plus the expected power required to run the Hall A target (including known or estimated transferline losses)
4) Will the CHL be in such a state that ESR can be supported by CHL

It seems to me that we might want to do the test on Thursday vs Friday, so if there is a trip or other issue Friday can be used for recovery if needed.


Thanks
Dave
