The Weston book Cold Cathode Glow Discharge Tubes mentions some tests of this. The findings are that sputtering is exponential. At constant current increases with current raised to the power of 2.5 and 1.5 at 50% duty if I remember correctly. As the perceived brightness also drops slower than duty indicates there would be a great benefit to use pulsed current. Muxed drive should then be an advantage if the peak current is kept down.
Maybe Dalibor could do some testing? That might have been of great interest for all of us in this group. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
