electron properties (AT) and x-ray properties

Well, the talk went pretty well. People told me they understood stuff and hadn't heard a comprehensive talk on this topic before. I have a few new contacts.

Now, I need to figure out what to do next. Basically, I see two areas. One is to start to really learn about radiation in undulators and keep in mind the question of whether the details of the electron distribution may yield something potentially interesting. The second is to be able to use AT better and make it better. Perhaps try to encourage and help write a non-linear dynamics optimization package? But this is still the ugly topic. Maybe this can be a foundation to do it better? We might as well at least implement some of the stuff that is known to work. And probably people already have. There's also the kick maps for tracking. Do I really recapitulate this history and keep going with the power series maps?

Hard to get motivated with this again, but I feel like its necessary (at least once more? probably multiple times...) When this problem gets too small, I completely lose interest. Need to remember some of the big questions, and think about clean implementations.
Overview:
1)Radiation brightness and beam size, 2) physics of one electron, 3) electron beam emittance, size and shape, 4)beam lifetime

The other issue here is the return to "work". I have to get back to concrete work with respect to understanding how the machine works, where the files are, and how to model it using AT. Expansion of networks and joining with other areas is important, but there has to be something there to join with. What is useful to model and understand? Can one be in some way comprehensive and systematic, or is this hopeless?
