total current out is 1.e-7 A.

T. Current at 275 A is 30nA.
Continue cathode heating to 290 A

So far no luck.

  168   Monday, August 13, 2012, 14:26 Pierre Bricault      In progressFEBIAD testI am done with the FEBIAD test (anode biased)
We will swap the bias now to the
cathode and change the polarity to negative.
  
  169   Monday, August 13, 2012, 14:56 Pierre Bricault      In progressFEBIAD testOne thing that seems to be strange regarding
this FEBIAD is the best results are without
any current in the coil.

for the FEBIAD with the biased cathode.
We found the source of the sparks.

on negative bias.
