Counterpoint (damage threshold)LaFortune, Kai Nicholas : We want indefinite lifetime for these optics (except maybe TFM). Therefore the shot rate isn't imporant here because we want "infinite" shots. Then what's left is rep rate effects on damage threshold. And we likely won't go to a low enough rep rate to get around that.
10 Hz issues:
Workshopping thoughts
Inspired by requests from MEC / LCLS workshop to do more than one per year (in this case implying open-ended)
Multiple mini-workshops? (Chapter 11 can be the basis for many topics)
Assumptions to get feedback on: what does it mean not to preclude dynamic tomography. ← this is a new workshop with those who came up with the idea plus maybe Diling, other X-ray experts: Diling, Corey, Rick Kraus team (originators Stefan, etc.), Sandberg, Ulf, David Montgomery, Luke, Arianna
Kai has proposal for how to define this, which could be discussed.
Recall original working groups. Need to go beyond this.
DELFI - what does it mean not to preclude this science case vs engineering issues (we will likely get a spectrum of definitions)?
Question: additional science use cases? - possibly, for higher refinement
Reviewing the current response to our requirements and see what iteration is needed.
Could make sense to have a longer UAP meeting with more detail on trade-offs
Don't make it just about getting through the slides: more interactive
