  • Direct conversion X-ray/gamma-ray photocathode
    Patent number: 5635706
    Abstract: A direct conversion broad band x-ray/gamma-ray photocathode having at least one layer functioning as an efficient x-ray or gamma-ray absorber and another layer functioning as an efficient transmission secondary electron emitter for providing both high detection efficiency and high spatial resolution, for use in either a radiation detection environment or an image intensification environment.
    Type: Grant

  • X-ray microscope with a direct conversion type x-ray photocathode
    Patent number: 5351279
    Abstract: A direct conversion X-ray photo-electron cathode has specially designed secondary electron emission layers which provides high efficiency, low noise, high speed and broad band X-ray photon detection. The X-ray photocathode is integrated with a micro channel plate and an output phosphor display screen to form a panel type X-ray intensifier. The X-ray intensifier is combined with a micro-focus X-ray source to provide projection type X-ray microscope for use in X-ray microscopic diagnostic applications.
