Have you decided how you will paint up the plasma coils? Will you do it like the computer image or go for a stereotypical glowing coil, like a lot of the plasma weapon images?
I'm of two minds how to paint the coils. While the Cherenkovian radiation is enticing when done well it detracts from the model when executed poorly. The amber coloured coils while conservative are well within my capacity to render so I'll stick with that.
Afterall Cherenkov radiation is not the tube itself but the medium in which the coils are immersed that glows. Neutrons moving through reactor coolant at a faster speed
than light velocity through that particular coolant is what makes the unworldly glow.
