The instrument consisted of a four-detector array of cesium iodide scintillators and photomultiplier tubes each surrounded by a tantalum ring shield to provide a directional system. Each detector was positioned so that its most sensitive direction faced 30 deg from the vertical. Pulse-height discriminators were used to provide gamma-ray energy loss thresholds of 0.06, 0.15, and 0.375 MeV. Gamma rays produced in the atmosphere by cosmic rays, precipitating electrons, and other means could be monitored with this instrument.
