user TURBO?s replication of Steven Mark?s TPU ?

[giantkiller]

My controller is 8 channels, 2 quad sets. I ran it previously on a 20# collector TPU#3. Didn't see anything. Switched to 3 freqs 1 per collector and saw harmonics. Now with what I have that gives kicks I would hard pressed to go back. But, the next step is the replacement of the pots so I could do a little dance all over again. The drift and lack of clock precision is probably good and bad.

We could make 3 or 4 outputs and drive the coils in a series configuration but using the next coils down, CW from it?

yes, that would work I belive.Ã,  There should be lots of ways to implement the mechanism to drive the coils in sequence.

Thanks for the attachments Grumpy, lots of good knowledge out there.

There is a mechanical implementation of this concept, and it has been patented by HydeÃ,  (if I remember correctly)Ã,  and others perhaps.

You rotate a cylinder that has sectors charged.

The stator around it is a coil.

The charge induced on the coil follows the rotor, so it moves, almost like a shadow that follows the object casting the shadow.Ã,   This method produces a very unique type of current.Ã,  A current that's formed by "dragging" charges along the surface!

By the way,Ã,  I'm not implying that this way of operation is what giantkiller, otto and others are doing.Ã,  They use square wave pulses which have lots of harmonics in the spectrum.Ã,   These harmonics, if tuned just right, will resonate at a perticular resonant mode of this TPU, and voltage will build to high levels, and interesting effects will become amplifyed.

I'm starting to feel like we are getting this thing cornered.Ã,   We've approached it from so many angles and we're zeroing in for the killÃ,   ;)Ã,

Hi Everyone,

Let me take a stab at Otto's statement about the rotating field.

A while back I posted a patent for a magnetically-driven particle accelerator and ever since I have been thinking about how a magnetic field can be used to drive particles around in a wire. According to the patent I had (US3935503A1) they talk about the fact that this special accelerator can move BOTH positive ions and negative ions and electrons in the same direction! One thing that has been messing with my mind is understanding how the current output of the TPU could be DC if you are feeding in pulses into the control coils that could force electrons in either direction from the coil. The answer was simple... Magnetic Mirror/Bottle!! Check out the explanation on here:

http://farside.ph.utexas.edu/teaching/plasma/lectures/node21.html

The magnetic bottle entrains both positive and negative charges so that they want to stay stuck in the part of the field that is least dense. In the case of this particle accelerator, either electric coils or a laser are used to create magnetic poles inside the accelerator loop (Collector coil  ). If the laser is used, the beam is shot into the perimeter of the tube and as it bounces off of the circular wall, it forms a polygon and the number of sides of the polygon determine the number of magnetic poles or Bubbles if you want to call them that. This set of poles then rotates around inside the tube and the particles get stuck inside the bubbles and are accelerated along with the rotation!!

Now if that totally confused you, lol, then here is the analogy for the electric coils. (This is all in the patent by the way I'm not making this up). The coils are arranged like an AC N-pole motor and phase shifted waves are sent into it (in this case sine waves). The coils set up a rotating magnetic field that does the same thing that the laser did. It traps the particles (magnetic bottle) and shoves them around in a circle!

But wait there's more! If you don't like the whole particle accelerator idea, check out this link:

http://www.daviddarling.info/encyclopedia/F/Fermi_acceleration.html

This article talks about something called Fermi Acceleration. This could explain two effects of the TPU in one! But here is the punch line here:

A mechanism, first suggested by Enrico Fermi in 1949, to explain the origin of cosmic rays. It involves charged particles being reflected by the moving interstellar magnetic field and either gaining or losing energy, depending on whether the "magnetic mirror" is approaching or receding. In a typical environment, Fermi argued, the probability of a head-on collision is greater than a head-tail collision, so particles would, on average, be accelerated.

So magnetic "shock waves" can cause charged particles to be accelerated! Another side effect is that the kinetic energy of the particle is increased... that means that it heats up! But wait there's more! The idea of a "shock" wave suggests that pulses are the way to go for the TPU! So if one were to create a pulsed shock wave rotating magnetic field (more like a toroidal shockwave), then we could "kick" the particles around in the circle (Like cannons!) and accelerate them with each whack of the magnetic field. The magnetic mirror effect is what would reflect the particles in one direction. So as long as the field rotates one way, the electrons will too!

Just my two cents worth 

God Bless,
Jason O

How a Cyclotron works:
The term ?cyclotron? was originally laboratory slang for ?magnetic resonance accelerator.?  A cyclotron is composed of two semicircular electrodes called ?dees? because they are shaped like the letter ?D.? These dees are encased inside a vacuum chamber that is exposed to a powerful external magnetic field. The application of a voltage to the two dees creates an electric field in the gap between them.  When ions (charged particles) are introduced into the center of the vacuum chamber, the magnetic field causes them to begin to move in a circular path.  As the ions cross the gap between the dees and they are given an energy kick that causes them to accelerate.  The ions cross this accelerating gap twice during each orbit. Because the strength of magnetic field never changes, the orbit of the ions widens each time they gain energy.  The accelerating ions continue to spiral from the cyclotron chamber?s center until they reach their peak energy at the chamber?s outer edge. At that point, the energized ions are drawn out of the chamber by an oppositely charged extractor and formed into a target-bombarding beam.  This demo model in which steel marbles are used to show how ions are accelerated in a cyclotron is the same one used by Ernest Lawrence in the display film.
