A simulated removal of a lower resonator from the Cyclotron tank was attempted by the RH group using the 
service bridge, lower resonator trolley, lower resonator attachment, and the (soon to be) attached lower 
resonator removal procedure on 2017-02-27. Prior to aligning the attachment over a lower resonator, a small 
piece of paper debris was observed falling off the trolley. A successful recovery operation was performed using 
the vacuum trolley; however, the lower resonator exercise had to be abandoned until a future shutdown due to 
scheduling constraints.
