Leak found on the Ne supply line. 1E-4 - 1E-5 range. Replaced fittings. Had to use one brass piece. Leak rate 6E-9 (probably due to Ne response). No
response to He.
Leak rate around low E-8 with regulation valve open. |

The helium bottle was found empty.
Rick will refill it and hook the leak detector on the system to find out
if we have a leak on the line. |

Gas line vacuum pump reinstalled after fitting was modified to receive a standard swagelok connector. The vacuum line was plumbed using 1/4" copper
tube (not Stainless) for the the ability to flex and manipulate the line for pump removal and and insertion. |

The reset restored the control.
But magnet supply does not put any amperage out.
Try turning it off and on. No chance. |

I went into the can diagnostics panel and reconfigure MB1 power supply.

I am done with the FEBIAD test (anode biased)
We will swap the bias now to the cathode and change the polarity to negative. |

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? |
