Re: What vacuum chamber do I use?

No plastics ever! Period. No glass ever.....If you want to do fusion.

Re: Power Source Voltage Ripple Regulation

To a stiff, (low Z) power supply, the fusor is a purely resistive load at all current draws. It is a dynamic resistance, (variable), based on pressures and voltage applied. Reactions between the gas load and any reactive circuit components can generate, a lot of RF radio noise. RF wise, the fusor is...

Re: Generate dense, cold plasma?

Positive waves....Do it...Report back...Provided one packs the gear needed to do it...or do anything about what they are talking about. Viable data tends to silence all critics unless the data is not viable....or....if no data is ever presented.

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...
