Re: New light

Your [top] fusor will act as a rectifier when you can see the 'beaming' as this is a self-stimulating beam sputtering electrons that ionise locally and therefore sustain the beam. You could try monitoring the currents, and it would be interesting to see if you can quantity the degree of rectification.

Re: First Reactor Test

Jeremy, your chamber is running at around 1~10 torr. You need to improve the vacuum by 4 orders of magnitude to create 'fusor' conditions, and preferably by 5 or 6 before you admit deuterium, if that is your end objective.

Re: No news is no news.

Actual EMC2 results are sparsely reported, but there has been recent presentations by Dr Parks that shows the best evidence of actual Wiffleball formation- high Beta conditions where the cusp confinement of electrons is greatly enhanced. According to Dr Nebel and others this is the most important a...

Re: No news is no news.

Under a recovery act funded project, following 'sole-supplier' USN funded work, EMC have demonstrated cusp confinement of electrons. This is a pre-requisite for the wiffleball theory of operation. Though there is as yet nothing to show that the formation of the electron wiffle ball can lead to viabl...

Re: My first XRT and some questions

We have a real time x ray microscope at work. 20uA is plenty for giving contrast in non-metallic objects easy, if not overexposed. I guess a head-sized object would need more like 50uA (not that the safety systems allow you to stick your head in it!! :) ). The max 200uA setting is for getting good c...

Re: My first XRT and some questions

It was a hunch that this could possibly be a steel transformer designed to operate at audio frequencies. Built on a steel framework looks a tad too bulky for a ferrite, but is clearly too light for a mains. Might be worth getting a frequency generator and an old audio amp out for some investigations...

Re: My first XRT and some questions

A question is whether it is mains, or is intended to operate at a higher frequency?

Re: Cosmic Rays?

There is a theory/prediction I forget the name of that shows the maximum particle energy to be found in cosmic rays to be of this order. Supposedly, we should see even unlimited energies, but due to the fundamentals of universal physics this is not so. It is fascinating to consider that such a proto...

Re: Another claim of a Fusion "Breakthrough"

Would high beta make neutral beam injection more efficient, for example? No particular reason to think so. Lerner has identified X-ray energy containment in his pulsed pinch machine, but he has specifically envisioned his machines as potential X-ray generators so it is relevant to him, but I don't ...

Re: A Rundown on Some of the Small Players

Success will be enabled by all the failures that proceeded it. It might be enabled by one or two well informed failures that proceeded it, but definitely not all. Some are just doomed from the outset, and can be seen to be so at an early stage if only there was no perverse incentive to talk up the ...
