Abstract

Disclosed is an apparatus for extracting multiple laser Compton scattering (“LCS”) photon beams using a laser Compton scattering reaction, the apparatus including: a linear accelerator for accelerating an electron beam; and an LCS gamma ray generation module including an LCS gamma ray generator for irradiating a target with an LCS gamma ray generated by emitting laser light to an electron beam released from the linear accelerator and a bending magnet for adjusting a direction of the electron beam passed through the LCS gamma ray generator, wherein at least two LCS gamma ray generation modules are sequentially arranged to form a closed loop together with the linear accelerator.

First claim

The invention claimed is:

1. An apparatus for extracting multiple laser Compton scattering (“LCS”) photon beams, the apparatus comprising:
a linear accelerator for accelerating an electron beam; and
at least two LCS gamma ray generation modules, each LCS gamma ray generating module including:
an LCS gamma ray generator for irradiating a target with an LCS gamma ray generated by emitting a laser light to an electron beam released from the linear accelerator; and
a bending magnet for adjusting a direction of the electron beam passed through the LCS gamma ray generator,
wherein the at least two LCS gamma ray generation modules are sequentially arranged to form a closed loop together with the linear accelerator.

2. The apparatus of claim 1 , wherein the at least two LCS gamma ray generation modules are arranged to irradiate the target in common with LCS gamma rays.

3. The apparatus of claim 1 , wherein the at least two LCS gamma ray generation modules generate LCS gamma rays of different energy from each other, thereby allowing photonuclear reactions to occur for targets of nuclides different from each other.

4. The apparatus of claim 1 , wherein the bending magnet bends the electron beam having a bending angle θ greater than 0° and less than or equal to 90°.

5. The apparatus of claim 1 , wherein the LCS gamma ray generator comprises:
a laser light source that emits a laser light; and
a mirror that reflects the laser light in the direction of the electron beam.

6. The apparatus of claim 5 , wherein the mirror comprises a multilayer structure mirror that reflects only the laser light of a predetermined wavelength band and that is transparent to LCS gamma rays.
