Abstract
Abstract The potential of nuclear track detector CR-39 as a means to characterize very low current beams of accelerator protons, deuterons and alpha particles in the energy region of 6 MeV/amu is examined. The beam radial specific density and its energy distribution are determined via semiautomatic video analysis of the recorded tracks for a Radial Ridge Cyclotron intermittent operation. Results show CR-39 to be capable of spectrometric measurements with variable resolution for the particles tested, and as a viable and useful medium for spatial isodose distribution applications at very low beam currents in biological irradiations. Scanning electron microscope analysis of the tracks and reaction rate calculations suggest Rutherford scattering as a likely cause of deviations in the energy discrimination ability for alpha particles.
