I see a lot of assertions and no math. In fact i see quite a bit of misunderstanding of fundamental plasma physics. The ion “scattering” cross section is generally defined as the 90Deg angle scattering. It is many many times higher than the fusion cross section, they do not stay confined. No matter what you do with one beam compared to another, it physically identical to having one set of ions stationary and the other colliding with them (your reference frame just moves with one beam–the results are always the same), in this case they just scatter, and your densities are way too low for any real fusion. Unless you have some uber magic accelerator. In which case light ion ICF is totally easy. We have not solved kink and sausage instability without a theta field and hence low beta limits*. There are many more things wrong with the physics sorry (Just asserting that XXX instability is not an issue does not cut it). Also the English needs work. Even the title does not make much sense.

It should be noted that Lerner has *not* swept any known plasma instability under the carpet. He has and continues to address every possible issue in this regard. This is why he gets publications out while a lot of the IEC crowed do not.

*There is shear stabilized z pinch. However there was only a few experiments so far, and only one with high currents. Oh and the so called advanced mode Tokamak which is also shear stabilized IIRC, but then there is these pesky ELM.
