In this paper we describe a prototype of the scintillating optical fiber isotope experiment (SOFIE) and give results of a Bevalac calibration using iron nuclei to study the measurement precision in range and trajectory which can be obtained. We have measured the range of iron nuclei with approximate energy 500 MeV/amu entering the SOFIE instrument to a precision of 200–300 μm, and their transverse position coordinate to better than 35 μm. These results indicate that scintillating optical fibers are very useful as a range detector and as a high precision hodoscope for heavy nuclei.
