Thanks for the debunk.  I just now read the article and was gearing up to say something similar.  All the hysterical claims are bogus, at least at the technical level.  As for situating this machine underground, does anyone have the slightest idea how unwise it would be to allow any stray particles from this to get out?  It would make an X-ray seem like sunlight.  Safer for everybody not to permit the possiblity...and probably the political price to pay for constructing it in the first place.  But thanks again.
