NEON- RE: small tube lifetime
Dear Tom W. or anybody else:
Do you know a physical reason why short tubes should have shorter life?
Temperature - NO. When properly processed, no outgassing will occur, thus
bombarding temperature is always much higher than operating temp.
Gas volume - you have to pre-compensate to have the optimal equilibrium
discharge pressure - no more occlusion in the 'trode body when equilibirum
is reached.
So please tell me a GOOD reason why small tubes should have shorter life
- I don't know any. My 6mm ones, 20cm long ore operating now for more than
2.5 years on 25mA (red) without any sign of ageing.
