The Status of the Track Imaging Cerenkov Experiment
Abstract content
In distinguishing between the atmospheric Cerenkov light initiated by the primary cosmic ray and its associated air shower, the Track Imaging Cerenkov Experiment (TrICE) is devised to measure the composition of cosmic rays at TeV-PeV energies. The instrument is a fixed-mount zenith telescope that uses a fresnel lens as a early trigger and 4m focal length spherical mirrors to produce the image on the focal plane over a 1.5 degree field-of-view. The TrICE camera, composed of multi-anode photomultiplier tubes with 0.086 degree angular spacing, is digitized continuously by a custom ASIC at 53 MHz with a dynamic range of 16 bits. Here we describe the commissioning and calibration of TrICE.
