A General Antiparticle Spectrometer (GAS) typically refers to a type of scientific instrument used in particle physics and astrophysics to detect and analyze antiparticles. Antiparticles are the counterparts to ordinary particles; they have the same mass as particles but opposite charge and other quantum numbers. For instance, the antiparticle of an electron is a positron.
