Is it possible for a bore coated with hard and dense metal alloy like tungsten or depleted uranium to reflect most of the Bremsstrahlung and other electromagnetic radiation back to plasma?
Yes. Bremsstrahlung radiation is in the X-ray region of the electromagnetic spectrum and most of the electromagnetic radiation from an aneutronic fusion is also in this range. However, only X-rays at very shallow angles can be more effectively reflected, hence an alternate layer of tungsten and boron carbide (W/B4C) can improve the X-ray reflection.
