Before revision: In accelerator physics, a beamline refers to the trajectory of the beam of accelerated particles, including the overall construction of the path segment ( vacuum tube, magnets, diagnostic devices) along a specific path of an accelerator facility.
After revision: In accelerator physics, a beamline refers to the trajectory of the beam of accelerated particles, including the overall construction of the path segment ( guide tubes, diagnostic devices) along a specific path of an accelerator facility.
