Comparison of Approximate Models for High Energy Cosmic Radiation Shielding Calculation

Comparison of Approximate Models for High Energy Cosmic Radiation Shielding Calculation

Two approximate calculation models for a cosmic radiation shielding in satellite are compared with detailed 3-dimensional calculation results. One is a sectoring method and the other is a chord-length distribution method. Shielding calculation is performed for KITSAT-1 under the assumed environment...
