Use of Semi-Dipole Magnetic Field for Spacecraft Radiation Protection
There are various methods to shield spacecraft from energetic particles, like one based on the usage of the permanent magnets. At the same time this method is not perfect; it only suggests low intensity magnetic field because of neglecting galactic cosmic radiation effects on human body. In this paper, hyper thin rings as a shield for spacecraft are suggested. Although these rings are lighter than permanent magnets, their ability to protect spaceship with a safe and high intensity magnetic field is higher than the magnets.
