今年建成了一个新的电子回旋共振离子源(LECR3-兰州电子回旋共振离子源3号)。这个源的主要目的是为原子物理和表面物理研究提供高电荷态离子束。该离子源的设计基于IMP 14.5 GHz ECR离子源(LECR2-兰州电子回旋共振离子源2号)，采用直接插入波导和铝室的双重射频加热方式。此外，等离子体腔的体积比LECR2的体积大，从而提高了高电荷态离子的射频功率和束流强度。但为了与LECR2的性能进行比较，腔壁上的六极子磁场保持不变。仅仅经过四天的条件训练，就得到了第一批测试结果。这个离子源的最终结果有望好于LECR2的S。(C)2002年美国物理研究所。
A new electron cyclotron resonance (ECR) ion source (LECR3-Lanzhou Electron Cyclotron Resonance Ion Source No. 3) has been constructed this year. The main purpose of this source is to provide highly charged ion beams for atomic physics and surface physics research. The design of this ion source is based on the IMP 14.5 GHz ECR ion source (LECR2-Lanzhou Electron Cyclotron Resonance Ion Source No. 2) with double rf heating by inserting waveguide directly and aluminum chamber. Furthermore, the volume of the plasma chamber is larger than that of LECR2 so as to increase the rf power and improve beam intensity for highly charged ions. But the hexapole field on the chamber wall is kept the same value in order to compare with the performance of LECR2. After only four days conditioning the first test results were obtained. The final result of this ion source is expected to be better than LECR2's. (C) 2002 American Institute of Physics.
