Fusor Repair
Posted: Wed Dec 06, 2017 5:11 pm
As I mentioned under the neutron detector thread, my fusor's cathode had issues causing shorting across the support structure (via metal that had deposited upon the glass surface by the exposed section of the rod (being sputtered) that holds the cathode.)
I obtained a new diamond band saw blade for my glass saw to cut the glass cylinder pieces to the correct length that my electrode required to shield/insulate the exposed metal section of the cathode - note that one of the glass shields is just a std chemical beaker that I cut off the base.
These short glass shielding cylinders surround the cathode and are epoxied to the main glass support plate (i.e. also my 8.2 inch diameter window port.)
