This project is the continuation of a large cosmic-ray detector at South Pole called the South Pole Air Shower Experiment (SPASE) that operates in coincidence with Antarctic Muon and Neutrino Detector Array (AMANDA). The main goal is to study the composition of ultra-high-energy (3 PeV) primary cosmic rays. These cosmic-rays interact in the atmosphere above South Pole and produce "showers" consisting of thousands of electrons and muons. It is possible by measuring the resulting cosmic-ray showers at the surface with SPASE and two kilometers below the surface of the ice with AMANDA to deduce something about the original nucleus that caused the shower. SPASE is also very valuable for providing diagnostic and calibration information for AMANDA.***

该项目是在南极进行的一个大型宇宙射线探测器的继续，称为南极空气簇射实验，与南极μ子和中微子探测器阵列同时运行。 主要目标是研究超高能（3 PeV）初级宇宙射线的组成。 这些宇宙射线在南极上空的大气中相互作用，产生由数千个电子和μ子组成的“簇射”。 通过用SPASE测量在表面产生的宇宙射线簇射，阿曼达测量在冰表面以下两公里处产生的宇宙射线簇射，可以推断出引起簇射的原始原子核的一些情况。 SPASE还可以为阿曼达提供诊断和校准信息。*
