Description

Technical Field

[0001] The present invention relates to the technical field of collecting radiation light after a high-energy ion beam bombards a target material, and in particular to a radiation light collection system when a high-energy heavy ion beam interacts with a target in a strong magnetic field environment. Background Art

[0002] The interaction process between high-energy ion beams and matter under strong magnetic fields is not only an important research topic in magnetic inertia coherence, but also an important physical basis for studying the science of inertial confinement fusion driven by high-current heavy ion beams.

[0003] In a strong magnetic field, existing atomic physics models, material properties, and the processes by which ions interact with matter will undergo significant changes. For example, when a high-energy ion beam bombards a target, the defects and excitations created within the target material, under the influence of the strong magnetic field, have new directional motion trends, causing subtle changes in the energy level characteristics of the target atoms and the material structure, thereby generating new physical phenomena and affecting processes such as the energy deposition and transport of ions in the material.

[0004] When a target is bombarded by a high-energy ion beam, the target material emits a characteristic spectrum after being excited and de-excited. Existing research uses high-precision optical diagnostic techniques to accurately describe and detail the interactions between ions and matter. These techniques have been widely applied in related fields and have yielded significant results. However, due to the unique characteristics of the strong magnetic field environment and the high-power ion beam target interaction process, the use of high-precision optical diagnostic techniques to investigate this bombardment process has not yet been reported.

[0005] The prior art discloses a system for irradiating target materials. The system is used to transfer target material capsules between a target irradiation station and a collection station, such as a hot cell, in a transport system. The system includes a beamline channel for passing an energy beam irradiating the target material, a target holder for holding the target material or a substrate backing the target material, and a housing for enclosing the target holder. This system only discloses ion beam irradiation of the target material and does not disclose a system for collecting the irradiated light after irradiation. Furthermore, the system does not consider the stability of the light collection system in strong magnetic fields.

[0006] How to ensure the stability of the optical system under strong magnetic fields, and how to ensure the efficiency and radiation resistance of the light-collecting system under the strong radiation background of high-power beam targets, are technical problems that need to be solved in the development of light-collecting systems. Summary of the Invention
