[Dsg-hallb_magnets] Hall B Sc magnets run

[Eugene Pasyuk]

I see that the magnets are already signed off in HCO. By the way, I am not on the list of people who can sign off for magnets.
Other than that it looks like a reasonable plane. We just need to make sure the we will have notification sent to on-call personnel in case there is a cryo or electrical problems over holiday weekend.

Subject: Hall B Sc magnets run

Dear Denny and Team

As discussed this morning, HallB is scheduled to get the beam on Dec2nd 2019.
Denny on Vacation till 2nd Dec and Dave and Bob will also be away from Lab.
In order to run the magnets to full field on Dec 2nd, the following is suggested-
1.      HOT check out (magnets) - Eugene P (sign off) Wednesday Morning/afternoon (27th Nov 2019)
2.      Magnet Sweep - Probir G and others (if available)
3.      Run both magnets to full field and back down to 250 A and park over the Thanksgiving time. This will not impact any other system, members needs to be aware off the magnets at field and no work is allowed within the boundary.
Please let me know if you have concerns, else we go ahead with this as our schedule going ahead.
Please find the attached Fall 2019 run rota list for your ready reference.

All information regarding the checks carried out earlier last month is saved at the following location-

Regards

Probir
