Inject pilot

  DR   LSA Other Agent
Drive X Load and/or check injection timing table   CBCM
Drive X Make request to CBCM with ring, bucket number, PS user (intensity) and number of PS batches    
Timing X Injection into LHC - injection kickers, BI receive pre-pulses. BST sends out acquisition event for BPMs, BLMs as required. Acquire [BCT, BPMs, BLMs, SRM]  
On event  

LFB,TFB,RF: Batch dependent settings triggered by timing events.
Jump phase loop onto beam (beam/cavity sum)
Switch synchro loop on

    
After kick X Acquire kick waveform   OASIS

 

Followed by post-injection checks - did acquisition, concentration, publish, timestamping etc. work? Repeat as necessary.
