Re: A Thought Experiment on Ideal Conditions

Good fusors regularly hit the mega n/s mark. ( 2 million fusions/s +) Grid losses in any fusor is pitiably small. There are many other losses of greater import keeping the fusor from improving. These have been discussed at some length in past posts. The grid is of no real concern, loss-wise. Due to ...

Re: Gamma-ray Spectrum, CP-1 Graphite Memento

As I understood it, there was no core in the classic sense in CP-1. Instead, the fuel was distributed all about and within the moderator in a manner that would allow moderation of purely natural uranium fission over the bulk of the volume. Explains the low power over a huge volume. I do not know how...

Re: Wendelstein 7-X has successfully finished its second major experimental run

Regardless, Fossil fuels will be the major suppliers of all electricity for a very long time to come. Fission will trail at a distant second. Renewables will never, ever, make honorable mention on a global scale. Current fossil fuel plants, actually planned or under construction world wide, number i...

Re: Overview of D-D and D-T Fusion Detectors

Of course it is possible to place a detection device inside the fusor or any fusion device. It will be possible once you design, create and test it out. Many things are within the realm of possibility. I have heard of folks putting PIPs detectors in such environments. I have also heard of a lot of P...

Re: Neon sign transformer power: a new look

The lamps are a non-linear gas load and only a bit like a fusor. To bad the tests weren't run on a real fusor which is what folks here might be interested in. Resistive loads are smooth and remain constant. The transformer is designed for a gas load. Neon gas loads are really just diacs, (voltage re...

Re: My progress II

How long did you operate it? Looking at your set up, It looks like you can seal your system off between the fusor and the pump with a valve. I suggest pumping as low as the pump can go and read the pressure. Record the pressure. Next close the valve and read the pressure rise and write it down every...

Re: Gamma-ray Spectrum, CP-1 Graphite Memento

As noted in my post, CP-2 was used actively until 1957 at an unknown power level. Thus, if all the CP-1 graphite blocks were used in CP-2 they saw a much longer neutron exposure time than CP-1.

Re: HV feedthrough & chamber insulation

Most people use alumina ceramic tubing on the grid stalk. No plastic or hot glue allowed.

Re: Negative Polarity Power Source?

If you really need fusor related stuff, a daily visit to the trading post is recommended.

That fabulous supply has been languishing, un-sold in the trading post since October 27th.
