Even if we could, we probably wouldn't want to, except under very carefully controlled conditions. There would be no way to control the effects on biological systems, and the potential for doing more harm than good is clearly present. It would be like trying to adjust the contrast on your TV by firing cannonballs at the controls. Imagine the energy of a bullet concentrated into a space the size of a proton. That's a typical cosmic ray.
