B Pinched plasma inside a neutral beam injector

[Andrewtv848]

TL;DR Summary

I was wondering if you could use a Z pinch as well as microwaves to heat a plasma inside a neutral beam injector?

Let me start this off with saying I am just a uneducated idiot, But after reading about Zap Energies sheared flow pinch reactor I was wondering if you could use a similar concept in a neutral beam injector? Like could you first compress and heat the plasma inside of a NBI using a pinch, then heat it using microwaves, accelerate it and neutralize it.
Its just a rough idea and I probably over looked something completely obvious but it would be nagging at me if I didn't ask.
thank you for your time,
Andrew

Did you look at the basic articles with respect to this topic?
https://en.wikipedia.org/wiki/Neutral-beam_injection

Neutral beam injection actually accelerates the ions that it uses after it strips electrons from ions before the acceleration phase. Then once the ions are accelerated it reintroduces electrons so that the fast ions could enter the plasma without being deflected , because the charge on both protons and electrons is the same strength but the mass differs by alot, so it is essential to accelerate the ions instead of electrons.
The gained kinetic energy then adds to the plasma energy by interactions.I don't believe your idea is meaningful because the NBI machine in of itself is a way to add reactants to the tokamak plasma while also adding energy to it.
+ to compress bare ions is much harder than to compress a plasma that is neutral also having electrons present because bare ions have higher electrostatic repulsion than if they are within a plasma that also has electrons.

On the microwaves part I'm not sure but I would believe that it wouldn't be efficient because the idea within a neutral beam injector is to cause the ion beam to gain linear momentum so that after recombination with electrons they can fly into the fusion plasma much like a car accelerates within the accelerating lane to flow within the highway traffic , only unlike a car on a highway the accelerated ions then interact with existing ones within the fusion plasma and share their energy.
RF heating is done directly to the tokamak plasma with antennas located on the inner sides of the tokamak chamber.
