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.

GlueX, or the Glue Hyperon Experiment, is a particle physics experiment that aims to investigate the structure of nucleons (protons and neutrons) and the fundamental forces involved in their interactions. The experiment is conducted at the Thomas Jefferson National Accelerator Facility (JLab) in Newport News, Virginia. It uses a high-intensity photon beam produced by a 12 GeV electron accelerator to produce a wide variety of particles through photon-nucleon interactions.

A spectrofluorometer is an analytical instrument used to measure the fluorescence properties of samples. It works by emitting light of a specific wavelength to excite the electrons in fluorescent molecules within a sample, causing them to emit light at a different wavelength. The emitted fluorescence can provide valuable information about the sample's composition, concentration, and molecular structure.
