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.
