Innovative Low-Power Dispenser Cathode Assembly for Space Communications and Miniature Applications

A groundbreaking miniature barium dispenser thermionic cathode assembly, developed by FDE Inc. in Beaverton, OR, operates at just 1.5 watts of heater power, making it ideal for applications in cathode ray tubes and high-frequency traveling wave tubes. Utilizing mixed matrix cathode materials, it promises long life and elevated loading levels essential for achieving high brightness and spot sizes in laser-cathode ray tubes for electronic cinema projectors. Notably, it has been selected as the electron source for a NASA project focused on space communications.

  1. A Low Power Dispenser CathodeAssembly for Space Communications Small Business Innovation Research FDE Inc. Beaverton, OR INNOVATION A power efficient miniature barium dispenser thermionic cathode assembly • ACCOMPLISHMENTS • Developed a cathode assembly that uses only 1.5 watts of heater power. The small size and low power make it ideal for miniature cathode applications such as cathode ray tubes and high frequency traveling wave tubes • Uses the mixed matrix cathode material to give very long life, or alternatively, very high loading levels Low Power Dispenser Cathode Assembly • COMMERCIALIZATION • Sales to date $100,000 • The main user of this cathode to date has been a developer of laser-cathode ray tubes. The innovation described here can provide the very high cathode loading needed to achieve the brightness and spot size required by the tube • Laser-cathode ray tubes are used in projectors for electronic cinema • GOVERNMENT/SCIENCE APPLICATIONS • Cathode has been chosen for use as the electron source in a NASA miniature millimeter wave traveling wave tube being developed for space communications Glenn Research Center Communications 3-087 1995 Phase II, NAS3-97038, 6/02 NASA Contact – Edwin G.
