Abstract

The invention provides an irradiation particle energy selection method capable of simultaneously generating ionization and displacement defects, and belongs to the technical field of space environmental effects, nuclear science and applications. The application objects of the irradiation particle energy selection method include various key materials and devices for spacecrafts. The ionization / displacement absorption dose and range of incident particles per unit injection are calculated under specific material state conditions on the basis of a Monte Carlo calculation method. The energy of theincident particles can be determined according to the proportional relationship between the ionization absorption dose and the displacement absorption dose, so that the condition that stable ionization and displacement defects can be simultaneously generated is ensured.

Description

technical field

[0001] The invention relates to an ionization / displacement synergistic effect, belongs to the field of space environment effects, nuclear science and application technology, and in particular relates to a method for selecting energy of irradiated particles that simultaneously generates ionization and displacement defects. Background technique

[0002] With the development of human spaceflight, the frequency of use of different types of materials and devices in the space environment is increasing, and the impact of the space environment on key materials and devices used in spacecraft is also becoming more and more prominent. 70 years of human space exploration practice has shown that the space environment is harsh on spacecraft, cannot be ignored, has an extremely important impact, and is an important cause of spacecraft abnormalities and failures. Among them, the impact of space charged particle radiation environment on key materials and devices used in space...
