Security checking system using X-rays and neutrons

摘要

Provided is a security checking system. The security checking system includes an electron beam acceleration unit for accelerating electron beams having at least one energy intensity, an X-ray guide unit converting the electron beams accelerated by the electron beam acceleration unit into X-rays to guide the converted X-rays into an object, a neutron guide unit, and a detection unit detecting the X-rays and neutrons passing through the object. Thus, nuclear materials within the object may be detected, and also, maintenance/repair costs may be inexpensive to improve economic feasibility.

主权项

1. A security checking system comprising:
an electron beam (eBeam) acceleration unit to accelerate an eBeam having at least one energy level; an X-ray guide unit to convert the eBeam accelerated by the eBeam acceleration unit into X-rays and guide the X-rays to an object including a cargo; a neutron guide unit to convert the eBeam accelerated by the eBeam acceleration unit into neutrons and guide the neutrons to the object; and a detection unit to detect the X-rays and the neutrons passed through the object, wherein the X-ray guide unit comprises at least one first conversion unit to convert the eBeam into the X-rays and at least one first collimator unit to guide the X-rays to the object, the neutron guide unit comprises at least one second conversion unit to convert the eBeam into the neutrons and at least one second collimator unit to guide the neutrons to the object, and a length of the second conversion unit is larger than a length of the first conversion unit with respect to a direction in which the eBeam is converted to the neutrons and advanced.
