Various polymers were irradiated with high energy ( keV) carbon and hydrogen ion beams obtained from a high intensity pulsed power source. Energy deposition was in the range of 0.1–5 J/cm 2 during each pulse, and ion penetration was limited to a few microns. The rapid energy deposition (<500 ns) corresponded to a dose rate of approximately 10 12 Gy/s and resulted in a considerable temperature rise in the surface material accompanied by the formation of gaseous radiolysis products in amounts as high as the volume of the surface layer in which they were formed. Analysis by scanning electron microscopy revealed that dramatic changes to the polymer surface had occurred in some (but not all) of the materials, which took the form of extensive porosity or roughening. © 1998 John Wiley & Sons, Ltd.
