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.
