Generation of parametric X-rays by using electron accelerator

Hayashi, Yukio; Kando, Masaki; Kotaki, Hideyuki; Kawase, Keigo; Homma, Takayuki; Bulanov, S. V.

We generate monochromatic X rays (10 keV) in a method called parametric X-ray emission. When relativistic electrons are injected into a crystal plane, monochromatic X rays are radiated toward the reflected direction of the crystal plane. A 150 MeV electron beam and a thin Si (111) crystal were used for this experiment. We measured the rocking curve of the crystal and found a clear peak around the Bragg angle. We conclude that this peak is due to the parametric X-ray radiation. In future, we will try parametric X-ray generation by using laser-plasma electrons, which is one of the useful applications for laser-plasma electrons.
