Abstract:

We request a test beam for the study of the response and calibration of the ATIC (Advanced Thin Ionization Calorimeter) detector. The detector is designed for a balloon flight program to measure high energy primary cosmic ray protons, He, and other heavier elements with energies ranging from 10 Ge V to 100 TeV. The detector consists of one interaction length of carbon converters with interleaved scintillators for the charge measurement, followed by 22 radiation length BGO crystal arrays for the measurement of electromagnetic shower energy from the hadronic interactions. A Monte Carlo study has demonstrated that the detector will perform as we expect. A beam test at Fermilab with 800 GeV protons, the highest available beam on earth, will assure the concept of the detector and will provide a basis for the precise calibration of the detector response.
