  We describe a dedicated cosmic-ray telescope that explores a new method for
detecting Cerenkov radiation from high-energy primary cosmic rays and the large
particle air shower they induce upon entering the atmosphere. Using a camera
comprising 16 multi-anode photomultiplier tubes for a total of 256 pixels, the
Track Imaging Cerenkov Experiment (TrICE) resolves substructures in particle
air showers with 0.086 degree resolution. Cerenkov radiation is imaged using a
novel two-part optical system in which a Fresnel lens provides a wide-field
optical trigger and a mirror system collects delayed light with four times the
magnification. TrICE records well-resolved cosmic-ray air showers at rates
ranging between 0.01-0.1 Hz.
