Abstract
A scintillator-fiber charged-particle track-imaging detector has been developed using a bundle of square cross section plastic scintillator fiber optics, proximity focused onto an image intensified Charge Injection Device (CID) camera. The tracks of charged particles penetrating into the scintillator fiber bundle are projected onto the CID camera and the imaging information is read out in video format. We have exposed our detector to beams of 15 MeV protons and relativistic neon, manganese, and gold nuclei and have obtained images of their tracks. This paper presents details of the detector technique, properties of the tracks obtained, and preliminary range measurements of 15 MeV protons stopping in the fiber bundle.
