A Report on the Sources Used for Leo Plasma Experimental Simulation

The simulation of the Low Earth Orbit (LEO) plasma environment is essential for understanding the effects of space plasma interactions on space systems and subsystems. Spacecraft charging and arcs are among the most significant problems related to plasma impact. These can cause variations in the physical characteristics of materials and spacecraft systems. Ground-based experimental studies are proposed to investigate the effects of a simulated LEO plasma environment. The experiments have shown that plasma effect variations depend on the applied conditions and plasma properties. One of the key factors determining the estimated plasma properties is the source used to produce plasma. Various plasma sources have been developed to simulate the conditions and properties of LEO plasma. This study presents various sources applied to generate a simulated LEO plasma environment. Different techniques used for measuring plasma characteristics are presented in the paper. Examples of the operating conditions and plasma properties are also addressed.
