Present: Fern Pannell, Stefano Mazzoni, Edda Gschwendner, John Farmer, Collette Pakuza, Marlene Turner, Matthew Wing, David Cooke

Follow up:

• The tables/values for the magnet settings for different plasma lengths/ uncertainty bounds will be ready before the start of the next Run. Comment: MT, it would be great if you could share them so that we can have a look before to understand dependencies and scalings. To do: DC to share the information. FP to put tables of camera pixel to energy / new camera position with beam position on the screen on the wiki.
• BG subtraction on the new spectrometer GUI still needs to be checked. To do: FP, DC on the first day of the next run.
• New GUI: Great progress, To do: FP to improve BG subtraction and combine the profile
• To do: FP, DC to present agreement of e-beam ICT and spectrometer measurements during the next meeting. 
• CLEAR: analysis also progressing. To do: DC to present at a future meeting

Run 2c design --> Discussion initiated by MT, now becoming urgent with approval of Run 2c and limited timeline

• SM: butterfly still best known method. Tests on synchrotron radiation were presented in yesterdays BI meeting
  • To do: Follow up with Joe and a presentation in PEB showing feasibility for expected AWAKE parameters, if positive, include window in the design of the Run 2c spectrometer and present preliminary options in TB
• MW: what is the status on the betatron radiation emittance diagnostics?
  • JF: physics case not yet complete. Still needs to be validated that it could work
  • To do (all): check for results in Barney's Thesis
• To proceed on the Run 2c design:
  
  • Define specifications. To do: MT to collect information
  • Next step: Discuss design options, validate design

FP presentation:

• Camera array and new spec camera complete
• To do: follow up on possible saving issue in the .h5 files for CAMs: 5-7, possibly ROI cameras
• To do: share instructions on how to use new camera including tables on the wiki
• To do: understand why beam appear split on the old spectrometer camera. Hypothesis: fire window. SM suggest installation of test target
• Waterfall plot in progress, first version runs smoothly
• Possibly a discrepancy in energy calibration between old/new cameras at the very high energy end (low dispersion) of the screen. To do: FP to investigate and estimate uncertainties.
