Automatic hydraulic clamping mechanism for a window foil holder of an electron beam irradiator

摘要

An automatic hydraulic clamping mechanism for a window foil holder of an electron beam irradiator includes a foil holder suspended below a flange at the bottom of a vacuum container. A foil is mounted on the foil holder and hydraulic hanging cylinders are provided at each corner of the holder and are driven to raise the foil holder such that it remains parallel to the flange. Once the foil is raised to be in contact with the flange a plurality of hydraulic clamping cylinders are energized to clamp the foil holder in place.
