Abstract :
The authors deal with the design of a space laser insulation system using surface tracking as the constraint. Various parameters that determine the surface tracking distance between the high-potential electrode and the ground pins were identified and studied. Computer simulations were used to simulate the electric field distribution with various electrical, environmental, and material parameters. A design guideline is devised based on a detailed 3-D simulation of the electric field, and a sample calculation is presented for an actual space laser. It was found that an insulating material with higher permittivity and better chemical stability, such as alumina, will result in a smaller tracking distance
