Fast track finding using radially pointing scintillating fibers

A detector layout using O(cm) long, radially pointing, scintillating fibers at large radius is investigated. Such a geometry allows discrimination between high and low p(T) particles based on their angle of incidence and because high p(T) particles deposit large ionization in one fiber, while low p(T) particles deposit small ionization in many fibers. A pixelated array of these fibers provides a phi-z projection of particle trajectories, from which the track parameters can be calculated. The simulated track parameter resolutions are presented, and some of the unique detector and electronics issues associated with such a design are discussed.
