Pulsed fusor

[Steven Sesselmann]

Hi guys,

One too many questions, is probably better than one too few

Has anyone experimented with a pulsed fusor?

Instead of using a static DC voltage across the grid, could one oscillate
the power and create synchronized smashing action and thereby
increasing the rate of fusion?

yes, larry leins has done a good bit of work with the pulsed fusor. search the forums, there was much discussion of this not long ago.

Many inventions rely on some kind of feedback loop, including the
krankshaft and flywheel arrangement.

Setting up a standing wave in a fusor could also be self governed.

Once the fusor is creating neutron pulses a geiger counter could detect
the neutrons and and govern a transistor or tube to feedback a voltage
pulse to the fusor. The idea is to create a feedback loop.

Steven - a Geiger will not detect Neutrons, they are not charged particles and do not ionise.

[Steven Sesselmann]

Right, it would need to be a neutron counter.

There is no doubt that some sort of feedback control could improve the very "seat of your pants" type of of control, used most successfully with the fusors that achieve rather high neutron rate counts.

But the micro level control that you are suggesting will be rather difficult to achieve, since the synchronizing needs to be on the sub pico-second time scale, and if you do the math on that, the loop bandwidth exceeds anything we presently know how to do.

Netron detectors would be too slow by probably 4 -6 orders of magnitude.

But... that said, .. some sort of feedback IS the right idea. The issue is how to do it.

Yes, the thought crossed my mind, due to the high temperature/particle
velocity, it is not quite as easy as generating feedback in a karaoke
machine.

On the same subject, I used to own a large Manfredi induction casting
machine (unfortunately I chucked it out ). It had a high voltage
transformer, two large valves which were tuned together and a bank of
high voltage capacitors and an induction coil. I can't quite remember the
cirquit but it was quite simple and it generated a very high voltage and high
frequency induction. It would heat up a graphite crucible with 500 grams of
metal in a few minutes.

A fusor is not unlike a valve, so maybe two fusors, somehow working in
together might be able to set up a high frequency standing wave.

Just food for thought.

I like the idea of using a standing wave, This could induce a lot of power and would lend to concentrating and locating it as required at a foci - this is the basis of sonofusion, but I don't think it has beed tried with an IEC. Food for thought indeed Steven.

Only a single Fusor is needed but ideally three independant RF drive sources from a common oscillator and a bit of phase control - perhaps a triple segmentated grid arrangement in the Fusor?
