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
There are minutes attached to this event. Show them.
