1. Al corona shield installed over end of the HV duct to suppress discharges from the sharp edge of the duct.
2. Some moving and shortening of cables to keep them from running close to different voltages.
3. Changed the angle bracket on the 3M bias-EE resistor chain to a plate, same position.
4. Moved the 164K EE resistor chain to sit flat against feedthrough K.
5. Moved the bias-EE spark gap to sit flat against the back of feedthrough K, required tapping a hole in the back of the copper clamp.
6. Cap and top of rack vacuumed.
7. Piece of shielding removed from top of HV rack |
