Before revision: Elements that are used in beamlines by experimenters for conditioning the radiation beam between the storage ring and the end station include the following: Windows - thin sheets of metal, often beryllium, which transmit almost all of the beam, but protect the vacuum within the storage ring from contaminationSlits - which control the physical width of the beam and its angular spread : windows are used to separate UHV and HV vacuum sections and to terminate the beamline.
