Re: Power Supply from an "interesting" XRT

I have one of those transformers but elected not to use it due to its smaller size and potentially limited duty-cycle. My Fusor overtaxed a couple that we’re about double the size so I didn’t want to risk damaging it. I hope it works out and am interested in how you ballast and power it. Mark Rowley

Re: TA DA New Use of Plasmas

Bob, of course. But that wasn't the point. The whole thing is comical from A to Z. It's just fitting to see a quack device operating on a frequency known for having issues.

Re: Simplified Deuterium System Drawing/Schematic

For the purposes stated by Joshua, my mega attempt will be done with the 60kV precipitator supply. If it fails then good, we know it's limitations but so far there's enough range left that it may be possible. When I start with the mods I post about it within the input power section.

Re: Simplified Deuterium System Drawing/Schematic

Richard,I have hit 500k n/s with my PEM cell arrangement but am limited by my power supply to go much further. In the next month I hope to have a mod completed to allow for a few more milliamps. I'll post BTI results and an accompanying vid when I make an attempt at the mega mark.

Re: Cube fusor build

Amazing work Jon. I may end up trying the cylindrical grid as well after a couple other mods are put in place.

Re: BTI Detector / Ultraviolet Interference

That’s a great thread Jon. After seeing it I vaguely recall reading it when first posted 13+ years ago.

I may try a brief exposure to UV from a carbon arc lamp in the next day or so. My main concern when doing so is to keep any thermal influence from skewing the test.

First attempt at activating Indium

The past few days I’ve been working on indium activation with my Fusor. To do so, I assembled the following: 6x6” paraffin moderator cut in half 1.5x1.5” sq indium foil LND7311 pancake at 900v Nucleus 500 digital scaler The indium foil was placed between the two 3” paraffin halves and placed 8cm fro...

Neutron Detector Ad / 1951

Anyone have knowledge of this detector and what the “special phosphor” is?

Re: Making Large Vacuum Chambers

Back in the early 2000's I made one from the top portion of an air tank for scuba diving. I never hooked it up to a secondary pump but the roughing got it down to 15 or so mTorr.
