【 摘 要 】

Hi-Cal (High-Altitude Calibration) is a balloon-borne experiment that will be launched in December, 2016 in Antarctica following ANITA-IV (Antarctic Impulsive Transient Antenna) and will generate a broad-band pulse over the frequency range expected from radiation induced by a cosmic ray shower. Here, we describe a device based on an array of silicon photomultipliers (SiPMs) for determination of the azimuthal position of Hi-Cal. The angular resolution of the device is about 3 degrees. Since at the float altitude of ∼38 km the pressure will be ∼0.5 mbar and temperature ∼ - 20 °C, the equipment has been tested in a chamber over a range of corresponding pressures (0.5 ÷1000) mbar and temperatures (-40 ÷+50) °C.
