To-do list

• Introduce delay cables after cavity to see if
  static erratic feature changes
• Diagnose IP BPM phase sensitivity
• Vary incoming LO phase
• Synchronously digitise bunch phase measured at
  stripline BPMs
• Once available, do IPC beamline tests

Board synchronisation option 1

• Use FONT5 FONT5A boards
• Run Dougs ATF 2-board DAQ
• Observations
• Empirically approximately synchronous
• Readbacks not available for FONT5A board
• SIS digitiser and ATF GUI not used

Board synchronisation option 2

• Use FONT5A board SIS digitiser
• Run standalone DAQ for FONT5A board
• Issue synchronisation signal upstream
• Observations
• Integrates SIS digitiser operation
• Board synchronisation ensured
• Requires synchronisation signal to be sent to the
  IP and readback issued to Epics (Doug?)
• Requires ATF to save FONT Epics data

• Mechanical LO phase shifter (slide 3)
• BNC-BNC cables
• 3 meter long
