Cosmic Ray Energetics and Mass Experiment
After launching from McMurdo Station in Antarctica, the balloon will stay aloft for 60–100 days gathering data on charges and energies of the unimpeded cosmic rays that strike the detectors.Maximum detectable energy level is determined by duration of the flight and size of the detector; a difficult barrier to get around for experiments of this type.[1][2] In order to answer these questions, it is of particular interest to investigate cosmic rays in the 1012 to 1015 eV region due to several theories predicting a change in elemental composition just below the knee.Because of the relatively low geomagnetic cutoff energy for cosmic rays near the South Pole, a cherenkov detector is placed between modules of the TRD to act as a veto for these low-energy particles.Although the experiment is designed to meet the structural requirements of the Columbia Scientific Balloon Facility, it is inevitable that some damage will be incurred to replaceable parts of the instrument.
