In July of 1989, the US launched a neutral particle beam accelerator into space as part of the Beam Experiments Aboard Rocket (BEAR) project (I wish I were making this up). The particle beam weapon reached an altitude of 200km, successfully did its thing, then returned to Earth and was recovered intact. It's now at the Smithsonian in D.C. if you want to look at it.

Anti-satellite particle beams, eh? Hmmm...
