SGH reviewed the modular concept for the muon detection chamber support system by others and developed a monolithic integrated structural support system that meets the aggressive physics performance requirements, including stringent alignment and tolerance requirements, and is less costly to build. The Gamma Electron Muon Collaboration (GEM) muon detection chamber support system consists of two cylindrical space frames, each nearly 18 m in diameter and 18 m long, housed in a cylindrical magnet. The structure provides support for the muon detection chambers. The trajectories of muons, along with the sagitta of the trajectories, are determined from the coordinates of points where muons pass through the detection chambers.
