Re: Generate dense, cold plasma?

Again, and as always, if anyone feels they might have an idea leading to fusion be it good old fashion Cold fusion, good old fashioned and continuously failing hot fusion, cold plasma fusion or any hair-brained ideas that will do fusion..........TRY IT! Report back to us with data and your process a...

Re: Paper on neutron counting using ZnS(Ag) phosphors

All of these issues came to the fore in 1999 on songs.com and later, the intranet fusor site. There were hornyak detectors, and I used the Bicron model with target rings of ZnS:Ag. I tried a 2" with PMT and found the .75% efficiency nearly worthless in my first fusion efforts. (It did work, but...)....

Re: Victoreen 450p question

Mercury vapor stuff has been replaced for some years with solid state stuff. Hydrogen thyratrons are as different as night a day. Let's say I need to switch 25kv in under 1 usec and the peak current will be 8,000 amps. The on-time I want to be about 3 usec and I want this done 800 times per second. ...

Re: Victoreen 450p question

These latter tubes are hydrogen thyratrons. I have written on this rather extensively here in these forums in the past. I have used them as high current switches in both Tesla coils and special high power discharge systems over the years. I have a boat load of these very special tubes purchased at v...

Re: Using a neon sign transformer for fusion

...."using this specifically as my cathode"..... I assume you mean a needle pointed cathode, as from Jon's old posting? If so, yes! Again, higher voltages and currents will do more fusion in most any cathode configuration. However, as voltage and currents go up, so does the power involved with the c...

Re: My first plasma

I have given instruction on how to avoid direct hot beam contact with a viewport window in an all stainless chamber. In short, mount you grid so that the north or south pole is viewed "dead on in the window. You may lose the pretty core image but the rays and beams will be seen well. There is zero c...

Re: Using a neon sign transformer for fusion

Wait! You are looking at the work of the king of fusion on this site. No one, and I mean no one, is in Jon's class including myself. To read the low and whimpy 540n/s TIER that he reports at 10kv -10ma, you would need the skill set of a pro, (some years of neutron measurement experience) as well as ...

Re: Meditation on fusion

I do believe the trace elements in the sun or any star are not worth thinking about as a way to fusion. Instead, those 2% elements, including the 28% helium are there solely due to the Billions of years of fusion that has been going on to-date. The hydrogen sort of resides in its own feces. These fe...

Re: My first plasma

Sir, I am glad Eduardo has a watchful parent at hand. Glass makes a fine demo device, but the tendency to over drive it is a powerful one. The demo fusor is more to allow the study of plasma and how they react as voltage and current are varied. The visual observations are of importance. The most int...
