Latest Patents
Among her latest patents is the invention of a channel plate electron multiplier of the discrete dynode type. This device is formed from conductive sheets that are stacked in closely spaced relation. Each sheet is perforated with apertures that align to create electron multiplying channels. The design features input and output cross sections that are approximately the same size, along with a concave shaped inner surface profile. This innovative design causes a majority of electrons to strike the inner surface close to the output end, thereby increasing the gain of the multiplier. Another significant patent is for a color cathode ray tube that includes a screen with concentric phosphor ring patterns. This invention also features an electron multiplying channel plate positioned between the screen and the electron gun, which includes a focusing control electrode that maintains a constant focusing action.
