【Abstract】 A novel type of end Hall ion source has been successfully developed for optical thin film growth by ion beam assisted deposition (IBAD). Its operating principle and I U characteristics were discussed with special considerations given to the experimental ion energy evaluation of the ion emission by penta grid probing.The ion beam intensity and distributions were also studied更多还原
