      CB sets motion cycle from 20.28mm to 64.36mm

      Observe a second, higher energy peak during the part of the cycle where the DSSSD is moved out - see attachments 9-10

      Peak appears only when moving out. Does not appear when moving in/out manually on beam storage plateau. Does not appear when moving in synched with ring, waiting less than the storage time, and moving out.
      All seems to indicate it is due to beam injection and not moving out fast enough. Very weak halo piling up? Should be clear in the data depending on rate / strips affected.

Understand the status reports as follows:-
Status bit 3 : White Rabbit decoder detected an error in the received data
Status bit 2 : Firmware registered WR error, no reload of Timestamp
Status bit 0 : White Rabbit decoder reports uncertain of Timestamp information from WR
