Mini-Magnetosphere Plasma Experiment for Space Radiation Pro-tection in Manned Spaceflight
摘要
Abstract
With the development of Chinese manned spaceflight,the planetary missions will become true in the future.The protection of astronauts from cosmic radiation is an unavoidable problem that should be considered.There are many revolutionary ideas for shielding including Electrostatic Fields,Confined Magnetic Field,Unconfined Magnetic Field and Plasma Shielding etc.The concept using cold plasma to expand a magnetic field was recommended for further assessment.Magnetic field inflation was produced by the injection of plasma onto the magnetic field.The method can be used to deflect charged ions and to reduce space radiation dose.It can supply the suitable radiation protection for astronauts and spacecraft.Principle experiments demonstrated that the magnetic field was inflated by the injection of the plasma in the vacuum chamber and the magnetic field intensity strengthened with the increasing of input RF power in this paper.The mechanism should be studied in following steps.关键词
