OUTPUT WINDOW FOR ELECTRON BEAM IN ISOTOPE PRODUCTION Russian patent published in 2021 - IPC H05H7/22 

FIELD: radioisotope production.

SUBSTANCE: invention relates to an output window for an electron beam from a linear accelerator for use in the production of radioisotopes. The output window contains a cylindrical channel functionally connected at one end to a vacuum chamber designed for the passage of an electron beam through it, as well as a domed cup-shaped head at the other end of the channel. The cup-shaped head contains a convex part having a protruding upper part designed for the passage of an electron beam through it. The geometry of the domed cup-shaped head is chosen so that to provide resistance to tension from the pressure created by a cooling medium circulating around the protruding upper part and the vacuum in the cylindrical channel, and to maintain combined thermal tension and pressure tension below the fatigue limit of material forming the outlet window.

EFFECT: possibility of the output window for electrons to withstand high pressure drops during the production of isotopes using a braking radiation flux with minimization of fatigue failure due to high dynamic thermally induced tensions caused by a pulsed electron beam.
