[Orcnet] 165C -- anybody got _really_ high temp circuit experience?

[Brian Conley]

Related Sidebar Information:
Back in 1984 when I was taking my comprehensive exam for my masters I was asked 
several questions about triodes.
This surprised me because all of my physical device theory up to that point had been 
solid state.
The reason I was asked is that University of Arizona had some sort of grant 
from an undisclosed agency to develop "Thermionic Integrated Circuits", 
essentially chip vacuum tubes or vacuum tubes on a chip.
The reasons were for the conditions you describe.
Perhaps this can give you two other things to search on.
(U of A & Thermionic ICs)
