|
I vacuumed inside the HV cage, though it has many small areas that are difficult to access so I am not sure how great a job I did.
Turned the bias up and again at 55kV I hear small sparks near the end of the HV duct that brings the cables from the rack. Cannot see anything.
If it is really sparking where it sounds like sparking, it must be from the edge of the duct to the faraday cage. |

|
The resistor/varistor combinations across the target + / -, tube + / - and target- / tube + have been remade and moved to the back of the power supplies
to limit the corona discharges at higher voltages. Pictures attached. |

|
Swapped the old 9pin connectors out and replaced with 2 5-pin connectors, same as on the modules.
See attached for current pin out diagram. Many of the wires are too short to reach the bottom sockets, so wires 2, 8, 9 are not connected in the
connector. 4 spots are empty on connector 2 (right). (6, 7) and (4, 5) are twisted pairs. Unused wires are tapped up out of the way, but we should |
