Discharge Tube Solid Thermionic Cathodes TRIZ Cases
- Multi-Material Thermionic Emitter Beams for Low-Stress Emission
CTE-matched insulating layers and suspended beams reduce cracking and thermal damage while improving thermionic emitter reliability.
- Graphite-Capped LaB6 Cathode With Annular Gap for Longer Life
An annular gap separates the graphite cap from the LaB6 emitter to control electric fields, limit degradation, and extend cathode life.
