The Solid State Photomultiplier (SSPM) recently developed at the Rockwell International Science Center, coupled with fast scintillating fibers can have a rate capacity of 10/sup 8/ tracks per second per cm/sup 2/ of fiber cross-section in systems for tracking of high energy ionizing particles. Relative to other approaches the SSPM can provide substantial improvements in spatial and temporal tracking accuracy. Results of preliminary experiments with 0.255 x 0.255 mm/sup 2/ cross section step-index-of-refraction fibers exposed to electrons from a beta source are presented. The experiments involved pulse height analysis of SSPM photon detection pulses induced by coincident scintillations in two adjacent fibers traversed by the same electron. The data for two different scintillating fibers tested indicate that meter long fibers of this type, optimally coupled to SSPMs, will be effective in detecting minimum ionizing particles.
