Description
Hi-Cal (High-Altitude Calibration) is a balloon experiment that will be launched in Antarctica after ANITA-IV (Antarctic Impulsive Transient Antenna) and will generate a wide beam pulse in the frequency range expected from radiation induced from a cosmic ray shower. In this work a device based on an array of silicon photomultipliers (SiPMs) for determination of the azimuthal position of Hi-Cal is presented. The angular resolution it provides is about 3 degrees. Since during the flight at the altitude of ~38 km the pressure will be ~0.5 mbar and temperature ~ – 20 °C, the equipment has been tested in a chamber at different pressures (0.5 ÷ 1000) mbar and temperatures ( –40 ÷ +50) °C.
