Hi Dalibour, It would be nice to get a copy ! Please make the scans of each page separate. It's a munch's work to rework it trying to get double sided pages. 600ppi bitmap is fine for text only pages. For pages with photo's 300ppi gray scale is fine. Markings from the library are easy to remove by PhotoShoping.... succes

I am also preparing a workshop for making nixie tubes at home, I am at the same point as Dan, leaking system ;-) You can watch my progress on http://dalibor.farny.cz I try to share all info, even sometimes too briefly and delayed.. As for the other questions here: - gas mixture search for "Penning mixture" - it is called after its inventor Penning (and Addink). It is Neon and Argon 0.01 - 1%. More or less argon increases breakdown voltage. - anode material use stainless steel, 0.2mm thick, photo etching - cathode material Cathode material has big influence on breakdown voltage (the same gas mixture: Molybdenum cathode 150V, Fe cathode 240V) I plan to use stainless steel 0.1mm thick (316L low carbon, vacuum casted). I disassembled a Z566M tube and did some tests on cathodes and I think it is stainless steel, Molybdenum would be much brittle and wouldn't melt in 1900C flame as this did.. - cathode distance use the same distance as in commercial tubes, somewhere around 1.5-2mm should be OK. more in Weston. - gas pressure 30-40 torr, higher is better, because it prevents cathode sputtering = longer lifetime, but higher pressure also means higher breakdown voltage and higher power consumption.. Vladimir, Dan, where are You from guys? I am from Czech Republic..

Weston, "Cold cathode glow discharge tubes", 1968, but it is (surprisingly) sold out everywhere ;-) is there someone so kind to provide me a PDF or some other ebook? Thank You!
