No. The x-rays are produced by a specific process in the plasmoid called bremsstrahlung and in an FF DPF plasmoid that process produces mostly x-rays. The specific energies of the x-rays generated are governed by the fuel, the temperature and the nature of the plasma confinement. The plasmoid is not a wide-spectrum energy source.
Bremsstrahlung is the main source of xrays and is very definitely wide spectrum. There may be some line radiation from impurities, but this push the losses up massively and is typically avoided.
The xrays are wide spectrum, there is no doubt about it.
