Supported modes for OP:

• Injection trajectory for up to 16 injections per user
  • First injection has all gates enabled (assume empty ring)
  • Subsequent injections with OP gate selection (PPM setting)
  • Injection pre-pulses used to trigger (SPS BST)
  • Data published after each injection
• Capture (one acquisition per user)
  • Slots and number of turns OP setting (PPM)
  • Trigger with msec delay from injection prepulse or start of cycle
  • Data published at end of acquisition
• Orbit data (basis = 1kHz average of all slots)
  • Continuous IIR filter with data stored to DDR (dual-port)
  • Acquisition properties:
    • Server action with filters (as for BPMOPOS today) (Get() only - not notified)
      • YASP will specify start, stop etc
    • Server action with notification (end of cycle)
      • Orbit data averaged over 10msec (fixed) for all BPMs or (two registers)
      • ‘orbitAverageDepth’ // how many samples to sum over (starting from the first sample)
      • ‘orbitAverageJump’ // how many samples to ‘jump’ between starting averages

If we want one snapshot per 10 msec you would put: depth = 1, Jump = 10

If we want averages over 10 sample every 10 msec you would put: depth = 10, Jump = 10

The new system with its operational APIs will be documented as a simple EDMS document. Lars will provide a suitable template to Athanasios.
