|
The fuse for both roughing pumps blows when roughing the chamber. With the help from Edi: disconnect the exhaust port on the roughing pump for the first
few hundred torrs of roughing. Reconnect and continue.
Seems the roughing pump RP1 pushes air towards the exhaust of RP2 which blows the fuse |

|
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. |

| As per Ray Dube for the FEBIAD anode bias test. The PS will need to be reconnected before a target is run. |

|
There was a short between the gas line and the heat shield - as the gas line insulator was not tied to the heat shield. A Ta-wire was used to tie the
gas line and keep it from touching the heat shield. |

Ray is finishing the electrical modifications for the FEBIAD with the biased cathode.
We found the source of the sparks. The disconnected target heater cables were resting on the Einzel lens cap.

|
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? |

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

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. |
