| 摘 要： | 作为强流离子源新型的LaMo阴极 ,其用于强流离子源阴极的实验结果表明LaMo阴极是一种有效的热阴极发射体 ,且该阴极用于强流离子源时 ,离子源放电起弧正常 ,使用寿命大大延长 (相对于LaB6阴极 )。本试验对LaMo阴极材料的制备进行了探索性的尝试 ,取得了较好的实验结果 ,但与样品LaMo阴极材料 (美国 )还存在着一定的距离。

| Abstract: | LaMo cathode materials,when used in an ion sources,is capable of providing high ion current at high temperatures.Two types of LaMo cathode materials,fabricated by powder metallurgy,were studied and compared with that imported from the United States.Our preliminary results show that several technical problems have to be solved to make commercial available LaMo ion sources. |
