A piece of equipment that will come in really useful…

A gamma spectrometry system that works with just about any scintillator, GM or proportional counter the GS-1100A with PRA and Intune.

I developed the GS-1100A specifically to use in my own fusion research lab. Used with a B10 neutron tube, it becomes a reliable neutron measuring source.

Note, it may not be suitable for pulsed neutron measurements, as the count rate is limited to around 3000 cpm.

Thanks for teaching me something I didn’t know, it makes sense, the detector should over time record a bell shaped pulse, with some neutrons arriving early and some late. The width of the pulse will be a guide to the ion temperature. Sinse the velocity varies with the square root of the energy, the difference in velcity at 100 Kev would be on the order of + or – 20%, which I imagine is measurable.

That sounds like an almost impossible task…, I assume this method can only work with pulsed fusion. If the fusion was a steady state reaction it would not be that simple, unless you could measure the neutron energy in a scintillator.

How do they measure ion energies?

I agree 100%, the experiment needs to be repeated and we need to understand the physics behind the effect, either way, it was quite interesting.

On the subject of bubbles, the STAR fusion reactor was regularly producing bubbles, usually I would get 10-20 bubbles in a few minutes (with the PSU supplying a bias). Once I switched off the PSU I no longer had a measure of the voltage on the cathode, but neutron detectors and x-rays were detectoable after power off, indicating that it was at least maintaining 20KV or more. Colliding deuteron beeams at or over 20 Kv will produce some fusion, the question is weather or not, the fusion reactions were powering the cathode bias. the answer is I don’t know…

I attach a diagram of the STAR capacitor..

PS. There are two patent applications STAR has already been published and another that I call STARDRIVE is pending

I thought one of the draws of fusion was that “runaway reactions” were impossible. 😉

Ivy, sorry, runaway reaction is the wrong term, it would be more correct to say “self sustaining”, and add “maybe” if you like.

What might have taken place is charge separation…, 50% of the reactions in D+D fusion results in a fast proton, this proton is able to escape the hollow cathode through either of the two appertures, resulting in a diametric ejection of positively charged particles. These 1 Mev particles easily climb up the -50 to -100 Kv potential, and go to ground, thereby leaving the cathode with a negative charge. What I was able to do, was to turn off the power supply that supplied the negative potential to the cathode, and watch as the reaction continued by itself. It should however be noted, that I had a 30 watt ion gun running, which supplied a steady current of ions.

This is a big claim, and I would like to repeat this experiment, with someone that could understand and verify the result.

Soon I hope..

During my first fusion experiments I was working mostly alone, but this time I would like to get a team together. I have a number of friends with the right skills, and a 20 year old son, who is a physics under graduate, and I am sure he will be on my team.

Reswan,

Very creative, I have seen similar rings made from old silver cutlery, where the prongs on a silver fork are twisted into these shapes.

925 means 92.5% fine silver alloy (the rest is copper).

I have a few ideas, and will get my jeweller to make something.

How about a design with two deuterons for the fusion supporters and one with a 3He for the ones that have been there and done that 😉

The wall-plug effiency is 1/250,000 at best. This experimental device is not meant for rapid pulsing. A generator would pulse at about 500 Hz.

Eric,

Not bad at all, if you don’t mind me asking, what is the radius to the BTI, and what calibration are they?

At 500 Hz you would be cooking away quite nicely.

Is my bubble calculator of any use, can you use it to get a Q?

Hi Guys,

l can help you with some jewellery for fund raising. When I am not tinkering with fusion reactors, I run a jewellery manufacturing and wholesale company.

You probably need a good ring design for men, that can be manufactured in silver and gold, that can be promoted as a fund raising ring for fusion research.

I imagine the ring would appeal to male students and science buffs, who want to show their support for clean green energy.

I will ask my designer to make some sketches.

It could be a good concept 😉
