英文摘要
ECR (Electron Cyclotron Resonance) nitrogen atomic source using microwave frequency 2.45GHz has been developed for use in the experimental study of the ortho-para ratio and the degree of deuterium enrichment of ammonia molecule which formed on the interstellar grain surface by the atom-atom addition reactions in molecular clouds. Magnetic field configuration for the plasma confinement was designed by 3D magnetostatic analysis, in order to achieve the nitrogen atomic source with the high flux and the high dissociation fraction.
