I experimented making lightening and radiation detectors with various neon bulbs several years ago. I biased the bulbs to just below the strike voltage, using them essentially as "miller effect" detectors. Worked.

welcome Doc Joe. I live a couple hours south of you in Oklahoma. It might be nice to meet sometime. I have many interests and lots of stuff, which I tend to share freely with other experimenters. There are some pictures of some of my early fusion experiments on the fusor forum, or you can friend me ...

That is a twin to the one I have in my desk drawer. It and around 19 other sliding nomagraphs have been my constant companions throughout my career.

This video does a better job on the explanation and you can see the pieces a little better.

I've read about this for years, but never built one to see what it's doing past the expansion/contraction of the inert gas.

It's kind of funny the comments people make about "old test equipment." Especially the kids I work with. My retort is "Test equipment will always do the job it was designed to do." Besides, much of that old stuff wasn't old when I acquired it.

I generally don't pile my projects up, I push them ...

I want to enter too! Here's five of my work spaces.
Garage bench east. Garage bench north. Ham station. Electronics bench Audio bench, littered with robots.

I didn't want you to win hands down without a little competition.

Cool Stuff Geo! I see your name frequently on the reflector lists I subscribe to. Glad to meet you!

Seems like you'd be better off in the long run to run a balanced output rather than to ground one drift tube. The matching is no more trouble than matching to a coax and you will have less loss due to heating in the transfer cabling. The termination impedance of your drift tubes will doubtless be ...

That's good stuff! Carl does a reasonable job of conveying science to a journalist as well. Kudos to Carl, keep the faith brother. My only question, (warning! warped humor) and this because I'm tall. Why'd you put the controls down next to the floor!

I have never seen a 6KD6 amplifier so they truel7y may be better. The amps I worked on in the middle 70s were the commercially made CB amps, marketed of course as "ham" amps. They were built as cheaply as possible and sold for more than they were worth. I have ham transceivers that use sweep tubes ...
