   if that would work only for charged beams or not, in the former the range   
   would be limited. How fast do charged beams dissiapate in vacuum?   
      
   Particle beams act primarily by delivering radiation dose, not by producing   
   electrical surges, although at close range they can cause direct heating of   
   the target.  A neutralized particle beam would work much better in vacuum than   
   a charged one, due to    
   the lack of self-repulsion.
