星际飞行中的辐射主动防护问题一直是人们研究的焦点,低地轨道飞行中采用的质量厚度屏蔽已经不能满足要求,必须寻找新的空间辐射主动防护技术和方法。在电场、磁场、等离子体膨胀等众多新的主动防护方法中,选取了等离子体膨胀辐射防护技术作为研究对象;通过注入高能等离子体使磁场膨胀,从而使空间带电粒子偏转以减少空间辐射对飞行器及航天员的辐射损伤。通过原理性实验,证明了在真空状态下,等离子体的注入可以引起周围磁场发生变化,且同一个点的磁感强度随着射频电源输入功率的增大而增大。其机理还有待进一步的研究。
The active radiation protection in interstellar flight has always been the focus of research. The mass thickness shielding used in low-orbit flight can not meet the requirements. Therefore, new active radiation protection techniques and methods for space radiation must be sought. In the field of electric field, magnetic field, plasma expansion and many other new active protection methods, selected plasma expansion radiation protection technology as the research object; by injecting high-energy plasma to make the magnetic field expansion, so that the space charged particles deflected to reduce space radiation on the aircraft And astronaut radiation damage. Through the principle experiment, it is proved that in the vacuum state, the plasma injection can cause the change of the surrounding magnetic field, and the magnetic induction intensity of the same point increases with the input power of the RF power supply. The mechanism remains to be further studied.
