  • Publication number: 20220332547
    Abstract: A support for a trolley, having a running surface that is formed on the support for the trolley, an upper chord, a lower chord and braces that connect said chords together, wherein the braces are designed to be flat, and each brace has a main surface that faces away from the support longitudinally between the upper chord and the lower chord. Two of the braces form a brace pair in each case and are arranged next to one another as viewed in the direction of the longitudinal axis of the support, preferably on the outside of opposite longitudinal sides of the support. To provide such a support, the flat braces are releasably secured to the upper chord and/or to the lower chord. The invention also relates to an overhead transport device having such a support and a trolley that can be moved along the support on the running surface.

  • Publication number: 20220104339
    Abstract: A linear accelerator system according to an embodiment is for generating an MeV electron beam. The linear accelerator system includes a linear accelerator cavity having an enclosure, wherein the enclosure is open at one end to provide an exit port for the MeV electron beam; and a switchable magnet unit designed to, in a deflection mode, generate a magnetic field within the linear accelerator cavity to enable at least one electron, emitted within the linear accelerator cavity, to interact with the enclosure due to deflection away from the exit port caused by the magnetic field. Accordingly, in an embodiment, in the deflection mode, an intensity of the MeV electron beam passing through the exit port is relatively lower than an intensity of the MeV electron beam passing through the exit port in a beam generation mode of the switchable magnet unit.
