2023-05-12 - Science Team Meeting Notes

• LCLS-II-HE discussions of what to do with our beamline
  • Eric: Complete overkill idea to just be another laser (Hasan email)
  • Different instruments had different ideas on what type of focusing to use. 
  • Speculating on why for XPP. Possibly their wanting to do cavity based XFELs.
  • Also multiplexing options. The final answer will affect our ultimate ops model in terms of available beamtime.
  • Early first light in 2027

• Tilo wasn't sure of what to do about the review. Instructions weren't clear enough.  Tilo was confused about scope of what they were evaluating per Luke as well.
• In practice, a few points:
  • Look at all positioning of diagnostics and how to control, protect that. ATLAS, imaging, etc. Controls, procedures, etc. Be cautious about it.
  • We hadn't fully de-conflicted in the review
  • SOP and pinhole cameras (in scope to comment on this?). Probably mostly affects requirements for what benches are around. 
  • Pinhole and streak camera diagnostics to compare timing and alignment - not so straightforward to implement except for maybe a low-res fixed one. 
• Learn lessons for PDR:
  • The committee needs to be ready. Doesn't much need scientific input.
  • Charge needs to be clearer perhaps. I speculate that they could be less 
• Did we really need a review for this work? We wanted to mark a line.
  • Vetting through a review had the knock-on effect of forcing us to think through some things that we might not have. 

Global requirements document is the place for science needs. Doesn't need to be stated in terms of the old flagship experiments

Epix 10k being tested at ELI Beamlines is likely.

EMP probes as well.

Beginning to discuss with intern Jennifer to prepare work on . 

CST code... Amir asked by Mikael to have review. Next week will go over plan. 

• This comes to mind in describing a risk or a novel solution that may not be currently incorporated in our thinking. E.g. contrast and rep rated plasma mirrors
