Automatic target changing device for inertial confinement fusion

Abstract

The invention provides an automatic target changing device for inertial confinement fusion, belonging to the field of experimental equipment. The invention overcomes the following problems that an existing inertial confinement fusion experiment is long in target changing period and low in target shooting efficiency. The device comprises a translation mechanism, a target library rotating mechanism, a target holder, a target seat, a target changing vacuum cavity and a target pose adjusting device, wherein the translation mechanism is installed inside the target changing vacuum cavity; the target changing vacuum cavity is connected with a vacuum chamber through a vacuum valve; the target seat is installed on the target pose adjusting device; and the translation mechanism comprises a mounting base, a screw rod, a target library sensor, a translation table, a drag chain, a first vacuum motor, a stroke reset sensor and a guide rail, the screw rod and the guide rail are both mounted on the mounting base, the translation table is fixed on a sliding block of the guide rail, the screw rod is connected with the translation table through a nut seat, and the first vacuum motor drives the screw rod to rotate through a gear set. The automatic target changing device is mainly used for automatic target changing of inertial confinement fusion.

Description

technical field [0001] The invention belongs to the field of experimental equipment, in particular to an automatic target changing device for inertial confinement fusion. Background technique [0002] Inertial confinement fusion is an effective way to realize controllable thermonuclear fusion, an effective way to solve the energy problems faced by human beings, and it is also the strategic commanding height of science and technology that developed countries are vying to occupy, which has great practical significance. The inertial confinement fusion target shooting experiment needs to be completed in a vacuum environment. Since the conventional inertial confinement fusion target shooting system can only be loaded with one target at a time, the vacuum environment required for target shooting needs to be destroyed after each target shooting. After changing the target, it needs to be re-extracted Vacuum, although changing the target itself does not require much labor and time, b...

AI Technical Summary

Problems solved by technology

The inertial confinement fusion target shooting experiment needs to be completed in a vacuum environment. Since the conventional inertial confinement fusion target shooting system can only be loaded with one target at a time, the vacuum environment required for target shooting needs to be destroyed after each target shooting. After changing the target, it needs to be re-extracted Vacuum, although changing the target itself does not require much labor and time, but since the diameter of the vacuum chamber reaches several meters to 10 meters, such as Figure 8 shows that it takes several hours to extract the vacuum and expose to the atmosphere before and after each target change, which leads to a longer target change cycle , the shooting efficiency is low, and a lot of energy is wasted in vacuuming
