Abstract :
Sets of image frames were captured from a CCD device exposed to continuous beams of high energy neutrons. The tracks of short-range fragments from nuclear spallation interactions in the silicon of the device´s pixels have been analyzed in respect of their frequency, intensity, directionality and other pertinent parameters. A comparison between these results and the predictions of computer code models of nucleon interactions in silicon is presented. Comparisons are also made with equivalent images of neutron events in an APS camera.
