I have a few niche questions related to the making of nixie tubes I can't seem to find definitive answers to anywhere. I have a feeling someone here would be able to help me figure them out.
1. I understand that the cathodes need a certain amount of separation to prevent arcing, but has anyone tried alternative methods of cathode production in an effort to make that space smaller? The two that immediately come to mind are sputtering tungsten coatings on an insulating material and the inverse of that, which is coating the back of the tungsten wire with an insulating material. I had also been wondering if it would be possible to prevent arcing some other way. 2. When working borosilicate during the tube construction, how hot do the components inside get? I'm thinking both in terms of components directly touching the heated glass and those not touching (including indirectly). I'm asking to figure out what thermal tolerances I should look for in materials used to make a nixie tube. 3. How thick are the walls of a borosilicate nixie tube? Ideally, I'd have as specific an answer as possible. 4. Why haven't new manufacturers of nixies made any top-view nixies like the IN-12? -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
