空間重離子輻照效應(yīng)評(píng)述

A review on space heavy ion irradiation effects

摘要: 文章對(duì)生物、半導(dǎo)體、光學(xué)材料、金屬、聚合物的空間重離子輻照效應(yīng)的研究工作進(jìn)行了評(píng)述，也闡明了深入開(kāi)展重離子空間環(huán)境模型以及重離子輻照效應(yīng)與演化規(guī)律的研究具有重要意義。研究表明空間環(huán)境中重離子的含量雖少，但由于其高的電離能力和穿透力，對(duì)生物、半導(dǎo)體、光學(xué)材料、金屬、聚合物等會(huì)產(chǎn)生各種輻射損傷效應(yīng)，導(dǎo)致衛(wèi)星信號(hào)故障、光學(xué)器件失效、金屬與聚合物性能及形貌改變，甚至影響航天員的生命安全。

Abstract: This paper reviews the studies of space heavy ion irradiation effects on organisms, semiconductors, optical materials, metals, and polymers. The model of heavy ion space environment, the heavy ion irradiation effects and material performance evolution are important research issues. It is shown that the relative number of heavy ions in the space environment is small, but the radiation damage effects on organisms, semiconductors, optical materials, metals and polymers can not be ignored for the high ionization and penetration capacity of heavy ions, which would cause the signal malfunction of satellite, the fault of optics, the performance and morphology changes of metals and polymers, even would threaten the life safety of astronauts.
