Re: Proposal of a progressive thermalization fusion reactor which mechanical gain is ≥18

Hello Patrick,

I downloaded your Multiplasma simulator and wondered if you could elaborate on the method you used to simulate particle motion. Did you use a PIC approach?

Re: Inner grid-size

This question should be posted in the new user forum. Additionally, please respect the rules of the forum regarding your first post and user name.

As a side note, Fusor.net is a wonderful resource but showing you have put some effort into the answer always helps in getting a detailed response.

Fry's Closing Down

End of an era for electronic hobbyists in the western states ... Fry's Electronics is closing down permanently. https://www.frys.com/ I have equal memories of them being out of a component they said they had and having the component I needed to fix/save a project. I always thought Fry's was signific...

Re: A 50kV supply with 33mA drive ability

Finn, Is your supply current/voltage mode controlled, or is it an open loop? If you are using feedback, how did you design the resistor divider for the voltage feedback? I find that this is the most critical part when designing a closed-loop high voltage supply. It has to be the right balance of DC ...

Re: Mass flow controller question

Many will say, use small ID tubing and a needle valve.

I use a proportional valve, pressure gauge, and closed loop controller for pressure regulation (you can buy or make the electronics pretty simply). It's pretty great, to set the pressure and have it stay constant.

Re: Mass flow controller question

That's a meter not controller. Besides the label, you can tell because there's no proportional control valve.

Re: Another (Preliminary) Report on Anisotropy

I'm glad you are looking into this ... I've long held that the data supports anisotropy in many fusor setups (but not all)

Re: Another Report on Anisotropy

The similarity isn't important at the short distance, it's that the anisotropy holds up at greater distances. Additionally, the cross-section of the tube presented to the source is a major factor, especially so close.

Re: Another Report on Anisotropy

I'm hoping my neutron camera will provide some more insight into my setup.
