Grid support structure for an electron beam device










Image Number 9 for United States Patent #5990622.

A grid support structure is provided for a linear beam device having an axially centered cathode, an anode spaced therefrom and a grid disposed between the cathode and anode. The grid support structure maintains a proper grid-to-cathode spacing across an operating temperature range of the linear beam device. The grid is comprised of pyrolytic graphite, and includes a central active portion and a peripheral portion, with the peripheral portion comprising a plurality of evenly spaced elongated mounting holes. The grid support structure includes an inner grid support and an outer grid support. The inner grid support may include a plurality of axially extending posts that engage the mounting holes of the grid. The grid may further include resilient tabs that engage corresponding ramped surfaces to bias the grid into position.
