[Dsg-rich] Fwd: rich hv

[Tyler Lemon]

Hello Marco, 

There is the DSG weekly meeting this afternoon from 1:00PM to 3:00PM and I will not be at work from 8:45AM to about 10:15AM on Friday. We could meet this afternoon after the DSG meeting, any time tomorrow, or later Friday morning. 

I have asked whether the lift is still where we could get to the HV cables in Hall B since Morgan Cook from Hall B Engineering said the lift would be moving early last week (his email to me is below, at the start of this email chain). Morgan also said that the cable labeled A-37 was left tied off to the side. The 'spare' HV cable was plugged into A-37 in its place. 

Also, I am not trained to operate the lift. We would need someone else, whether from DSG or Hall B, to operate the lift. 

Best regards, 
Tyler

Dear Tyler, 
can we plan a visual inspection this week, while I am 
at Jlab. Due to the tight CLAS meeting schedule, I 
have limited time windows. At a first glance I would 
say: this early afternoom (preferred) or Friday early 
morning. May you check if we can go in with the lift 
and DSG can drive me there ? 
Do you know if A-37 is still in place or has been 
unplugged ? 
Thanks, Marco.
