Lattice Confinement Fusion in a Cube Fusor

[Cinar Kagan]

This is not like other people who want to improve fusor efficiency with weird and truly unachievable methods for amateurs but a rather theory for understanding the environment inside fusors, especially cube or cross fusors with Ti endcaps.

In papers I've read of NASA's researchers, they say that neutrons, electrons and ion beams interacting with TiD2 targets generate low but a detectable flux. The beams that hit the endcaps of a cube (I will just refer to the cube from now on) are e- particles and D2-/D- ions. I am pretty sure e- particles do not have sufficient energy to induce fusion via recoil and D2-/D- ions just cause the BOT reactions we all know of.

Neutrons however, created in the BOT and the beam-beam, beam-gas, beam-fast neutral...(the list goes on) can cause recoil in the D/D2 in the Ti target of a cube, causing both OP(Oppenheimer-Phillips) and fusion with another D/D2 embedded in the target. Of course, the rate of OP reactions in the Ti target is too low to even detect the minuscule amount of radioactivty with an HPGe above noise.

This might all be nonsense of mine, I leave the experts to judge.

Cinar - It would have been nice if you had not put an acronym that folks are going to have to look up in your post title.

Spelling it out would have been better, so that people would know instantly what you were talking about instead of having to look it up.

Like I just had to.

Unfortunately, I don't think you can edit the title of an initial post after it is created... oh well.

LCF --> Lattice confinement fusion.

Joe, I saw your post now and turns out I can, in fact edit the title. Now it is titled "Lattice Confinement Fusion in a Cube Fusor".

There are many others on this forum far better suited to this topic, but I will share my thoughts.

To my knowledge, no beam-on-target fusor built by a forum member has pre-loaded the titanium target before installing it within the chamber. The deuterium that does become trapped on the target does so via ion bombardment or surface adsorption. This means the deuterium within the target doesn't exceed a depth greater than a few microns.

The neutrons coming from deuterium fusion have an energy of around 2.45 MeV, this affects the potential reactions in two different ways.

The first consideration is energy transfer, a direct collision between a neutron and any deuterium trapped in the target can transfer over 1 MeV of energy. This is unfavorable, as this excessive energy reduces the likelihood of fusion occurring.

The second, and more pressing issue, is that the mean-free-path of the fusion neutron is vastly greater than the actual depth that deuterium occupies in the target. Basically, all fusion neutrons will exit the deuterated volume before any interactions can occur.

If we were looking to enhance these proton recoil derived fusion events, we would want to utilize a target with a large deuterium volume. This would both increase the likelihood of proton recoil occurring and allow for the recoiled deuterons to slow down to better fusion cross-section velocities via subsequent collisions before exiting the fusible area of the target.

Again, this isn't my area of expertise. Hopefully, someone better learned can step in.

Cinar, as you point out, even really advanced labs struggle to even detect fusion in most those applications using lattice confinement. That is far beyond anyone here for the most part. As for beam induced fusion, that is, of course, was the first successful fusion back in the 1930's. Whether any such process could create more energy then consume is an open question in the real fusion community but no one has decided to pursue it in a serious manner. So, that might or might not work.

As for surface confinement (or very shallow lattice confinement) fusion Ryan addressed that very well.
