Re: First Plasma

Jon-Thanks
At lower pressure the center becomes faint and a green jet appears.
Guess it is the electron path. Next time, I will use the RGA. Getting ready

Raymond-Thanks
I used a 8 Meg camera with a macro setting through the 25mm sapphire

Re: New fusor "Carl's Jr." nearing operability

Carl-nice job
I would like to use the oil idea. What is the "safe" oil gap to voltage ratio?
What oil type and where is it sold? Do you plan to cool the flanges? We
have used a conductive epoxy, are you using solder?

Re: Vapor Pressures

I bought my copy in 1962, cost $16.50. It must be a good book, as the pages
