Transcript of ACCOMPLISHMENTS
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

INNOVATION
1995 Phase II, NAS3-97038, 6/02NASA Contact – Edwin G. WintuckyCompany Contact – Bernard K. Vancil
A power efficient miniature barium dispenser thermionic 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
