A manostat was added to the 700B magnet on 10/14/2013. It did not alter the lock level drop and Z1 drift behavior. Opened a ticket (#150200) with Bruker on 10/16/2013. They analyzed the stability data and looked at stability data with just supercon shim and supercon shim + RT Z1 shim alone. Bruker's final conclusion is that the supercon Z1 needs touching. Currently, awaiting Bruker's recommendation for the course of action.
