Effect of Coulomb collision on the negative ion extraction mechanism in negative ion sources
To improve the H− ion beam optics, it is necessary to understand the energy relaxation process of surface produced H− ions in the extraction region of Cs seeded H− ion sources. Coulomb collisions of charged particles have been introduced to the 2D3V-PIC (two dimension in real space and three dimensi...
