In this world, the law enforcers and Military uses a new, multipurpose weapon which is basically a:

Packed into a single weapon. However, when designing the weapon, it's important to determine the parts that can be interchangeable in these two systems, so the question is:

What can be made into the shared parts of a free electron laser and a railgun, with nanotechnology?

  • Reversible, quick changes are allowed in the parts.

This question is tagged science-based because both of these systems exist in real life.

    $\begingroup$ A coil gun typically shoots ferromagnetic projectiles, can you provide an example of one shooting plasma? Also a plasma is very different from a beam of electrons if I am not mistaken. $\endgroup$ Commented Apr 8, 2017 at 16:18

  • $\begingroup$ @JoeKissling Well, it's close enough, but I still need the electrolaser to keep it alive. I recommend looking at the undulators. $\endgroup$ Commented Apr 8, 2017 at 16:24
  • $\begingroup$ In fact, I don't know if coilgun would even be practical for accelerating plasma. I think it would just end up compressing the plasma. $\endgroup$ Commented Apr 8, 2017 at 16:35

    $\begingroup$ I read the Title line ok, but did not understand the body of the post. Two main parts? But the title indicates they are two different systems, not parts of a whole. $\endgroup$

If you have nanotechnology, you won’t have “parts” in that sense. As I elaborate in this older post, you’ll have a lump of utility goo. There may be specialized nanobots for some purposes like superconductors, but for the most part all the “goo” is a shared common component.
