A power efficient miniature barium dispenser thermionic cathode assembly

• Sales of $100,000 per year
• The main user, Principia Light Works, 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 tube is being developed to be used in lamps

• 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

• Cathode has been chosen for use as the electron source in a NASA miniature millimeter wave traveling wave tube being developed for space communications
