An all-optical Compton scattering device containing an even-order aspheric reflector includes an ultra-intense incident laser, a gas target, and an even-order aspheric reflector. A beam of ultra-intense laser is incident on the surface of the even-order aspheric reflector, and after being reflected by the mirror, it converges on the z-axis and reacts with the gas target to generate an ultrafast electron beam without phase loss. During the propagation process, the electron beam generates self-synchronous continuous Compton scattering with the focused strong laser. The present invention integrates electron acceleration and radiation generation into one, and utilizes the converging effect of the even-order aspheric reflector on the laser to greatly improve the energy of the electron beam and its collision efficiency with the laser, so that the radiation is enhanced and the damage of the reflected laser to the optical element is avoided. The present invention is a beam focusing device suitable for laser tailfield electron acceleration, and relates to the field of laser tailfield electron acceleration and the generation of its radiation source, and in particular to the field of all-optical Compton scattering based on the laser tailfield.

This utility model discloses a screening device for producing high-slag-erosion-resistant iron trough castable, specifically relating to the technical field of screening equipment. It includes a driving component for driving a screen frame to screen the iron trough castable. The driving component comprises two screws respectively located on both sides of the screen frame, with the screws externally fixed to the screen frame via a buffer component. A movable shaft is located at the bottom of the buffer component. This utility model uses a servo motor to drive the screws to rotate. The screws drive the movable shaft to rotate synchronously via a first pulley, a belt, and a second pulley. Thus, when the screws drive the moving seat to reciprocate the screen frame, the movable shaft drives a lever to repeatedly move a spring-limited connecting plate up and down. This causes the material on the screen plate to not only be pushed but also thrown up and fall freely due to the up-and-down movement of the screen plate, creating a compound vibration. This also increases the collision efficiency between the material and the screen frame, achieving the purpose of breaking up material agglomeration and preventing screen frame blockage.
