Present: Matthew Wing, Fern Pannell, Davide Cooke, Edda Gschwendtner, Nikita Zena van Gils, Marlene Turner

Nikita:

• Progress on correlation between acceleration events and other experimental parameters:
  
  • Halo not a good predictor 
  • There may be one BPM in the electron beamline
  • Q (DC): could one use the BPMs upstream to predict the trajectory downstream?
  • C (DC): it may make sense to apply cuts, i.e. to select for round halos and then look at other correlations

Fern:

• Progress on acceleration events:
  
  • Oct 18 at 6.2e14: still clear increase in e-energy with step, SPSC events were rather typical events --> better show full waterfall or histogram in the future
  • repetition of these parameters in May: less clear, but also a different e-delay
  • June measurements have high reproducibility (~80%) in acceleration events

To do (discussed previously):

• Emittance analysis for different cameras
• Analysis of the 3.8e14 acceleration events in Oct
• Correlation between acceleration events and laser alignment and proton beam alignment
