'evening chaps.
I much enjoy reading your respective project posts, but now it's time for one of my own:
CERN is about to flip the big switch, and in commemoration of the event, I was thinking about how hard it would be to do a serious scale down of the LHC injector (IE, a linear accelerator).
Daunting task, eh? I don't know where to start to design. I know HOW it works, but not the design roadmap. For example, I know the LHC designers sat down and said "We want to hit 7 TeV." Did they start with the target eV number, the power supply, the available space? I don't know. I also have extra limitations. $, size, complexity, etc. Can I realistically anticipate, say, 5 Mev in under 8 vacuum feet? 10 feet? How about 2 MeV? Do I start with the PSU, aiming as high as I can in output and working from there? Or the vacuum vessel? Frequency delivered? At what point do I start sizing the drift segments, and how (many, often, spaced, length)? Beam narrowing? Spacing, synchronous power application with acceleration, vacuum backfilling? Source injection? I didn't anticipate building a duoplasmatron :p
I'm betting there's a way to calculate all these things based on some basic parameters, I just don't know which point to start at :) Anybody built one? Or know someone who could start me out? I'd much like to talk to someone in the know, so to say. Or just know a good book, for that matter?
