【摘要】 对从丹麦进口的９１１Ａ型中空阴极离子源进行了重新设计，经多次出束调试及改进，离子源部件已基本国产化。气体束可达到１０－５Ａ；固体束最大可达到１０－６Ａ，一次填料可持续稳定地工作５ｈ左右。更多还原

【Abstract】 After many tests the 911A hollow cathode ion source was redesigned and rebuilt. Now it is much easier to maintain than the oriaginal model. For gaseous materials the maximum beam current can reach to the order of 10 -5 A, while for solid matters to the order of 10 -6 A. The beam current is fairly stable and able to last for about five hours.更多还原
