This morning the pressure was 3.5E-7 T. Current at 275 A is 30nA.
Continue cathode heating to 290 A during meeting.
Start seeing some electron current from the cathode around 275 A. |

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. |

Lost communication with EPICS. Came in reset the ...
So far no luck.

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

This morning I try to contact PS group no one answer. Dan Louie is in vacation.
I went into the can diagnostics panel and reconfigure MB1 power supply.
This worked. |

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