[neonixie-l] Re: IN-9 tube gas discrepancies and cathode poisoning issues

[start end]

With DC high voltage power supply, the plasma didn't anchor to the bottom. 
With 50Hz square wave pulse current, the tube worked correctly.

Thank you for your reply.

Of course I used a current-controlled power supply. In addition to it, I 
added a 555 timer to trim the continuous current into 50 Hz square wave 
pulse current.

The only way I got my IN-9 to behave rationally was to use a 
current-controlled power supply.

There are many advantages with pulse power supply: 
1. Saving energy
2. Stabilizing the plasma 
3. Reducing heat emission
4. Preventing cathode poisoning
