Re: Optimal Deuterium Gas Pressure?

No such equation exists, period. As Dennis notes the pressure/voltage will be determined by the size type and configuration of a specific fusor system. The optimum pressure is whatever it turns out to be for a given system configuration and power supply. In all cases, fusor output energy per unit in...

Re: Calculation for Deuterium Pressure?

Reading the FAQs would answer all of your questions. In general, more pressure means more nuclear fuel you have to fuse. The higher the pressure, the better. Flies buzz around this ointment, however. More pressure means early onset of arc conditions at lower voltages. Arcing does little but burn up ...

Re: A bit more on hamfesting (buying and selling)

You question is answered in firm and certain terms in the URL I supplied in the above posting. It is my manifesto on hamfesting. Here goes..... Everything is sold as is! You buy it, you own it! No crying in your beer, no whining, just wheeling and dealing. No excuses given or accepted. In general, y...

Re: Update on Reactor Plasma Imaging Project

Congratulations. We have another winner at the Intel International science fair! I think there were two, maybe three others from the forums who won big time based on their use of a fusor in the past.

Re: Deposition within a fusor

The patterns are mere permanent depositions on the chamber walls miming the shape of the respective grid openings, based on beaming patterns. Not a big deal at all and to be expected with higher current drives over long periods. In the past other have posted images of the fixed patterns of depositio...

Re: First Plasma

The gauge, even if in perfect working order and purchased brand new, is worthless for reading a vacuum. It tells you nothing at all about the real pressure in the system. Read the FAQs and look at the photos.

Re: Hitachi hv supply

This is no toy, It is real the deal and can be the ultimate fusor supply that will not be killed very easily. the connection are labeled a bit arcane, but need to be metered and that might not tell the tale. One might make a guess based on the terminal designations. Assuming it is on the norm for su...

Re: Foreline pump base pressure degraded

The obvious assumption is that you have fresh oil in the pump of very recent input. If not and you want to try to keep the oil. Follow the suggestion of gas ballasting for two to three hours with the inlet blocked off. Smart money would just replace the oil. with new oil, still gas ballast for a few...

Re: Usable transformer

Nice memory and catch Rex. good luck on getting the supply to work. Finn noted the circuit shut down at overload. Sounds like what the pro-supplies do when operated in the normal mode. Again, good luck.
