Has there been any progress of the AWAKE accelerator technology? https://home.cern/science/experiments/awake https://home.cern/science/experiments/awake Seems l

  Not on AWAKE specifically but there's been some exciting progress made using supersonic jets of neutral gas as decent lenses for wakefield accelerated beams. This solves the problem of having a tiny accelerator with a wakefield (not counting the size of the driving laser/beam/whatever) but still requiring large/bulky sections for quadrapole electrostatic lenses and the like.

  There was a discussion over at Physics Forums regarding wakefield acceleration. https://www.physicsforums.com/threads/two-stage-electron-wakefield-acceleration.948303/ https://www.physicsforums.com/threads/two-stage-electron-wak... Note that mfb works as a physicist in the CMS detector team, Vanadium 50 and ZapperZ are current or have been high-energy physicists as well. In summary, issue seems to be that the strong acceleration provided reduces beam quality, which kind of negates the gains you got from the higher energy. Though it doesn't seem to be a fundamental limitation, just a difficult engineering issue.

    I always thought mfb worked on ATLAS

      I can't find the reference right now, but in one thread he said something about how the CMS team did their analysis and then commented along the lines that ATLAS did something similar but he wasn't sure of the details. That's why I got the impression he was on the CMS team. Anyway, he works with one of them, so he's not just a random internet armchair expert was my point :)
