Robert and I went yesterday and today to the end-Y station to do some work related to line-hunting. 

Yesterday, we shutdown the MAD CITY LABS nano-drive located on top of the laser table in the VEA room and we also shutdown the CNS Clock II located in the computer room (both systems were shutdown for about two hours). Today, at ~10:58 local time, we shutdown the ESD Pressure Interlock for about an hour. 

Pictures of the three systems are attached to this log.
