Yesterday Ray Dube has changed the configuration in order to run the FEBIAD with the cathode on negative bias.
There were a short between the gas line and the common. The box has been opened and the short removed.
This morning I am turning on the cathode heater to 290 A. |

One thing that seems to be strange regarding this FEBIAD is the best results are without any current in the coil.
Normally for the neon ionization the on-line source wanted to be at around 50 to 80 Amp. Not this one.
Is there anything special about this coil? |
