I think afew will learn everything in the film linked by Pierre, but solar wind is really not the most important already in the energy regions which would be interesting compared with LHC. Sun wind reaches less than 1 GeV.

The Supernova accelerated ones are the relevant for the comparison with LHC.

The really high one, e.g. those which are watched at Auger have most likely their origin in active galactic nuclei.
