Fascinating stuff indeed! A couple questions: 1/ Is there any possibility that the dimple you inferred from your laser reflection could in fact be a (field-generated) goose pimple? In this case it could concentrate the field lines, so that some or all of your emitted ions, after having spread out from your emitter as expected, refocus to hit the dimple rather than the less attractive surroundings. 2/ Have you observed those airstreams on a solid collector?
