摘要
文章涉及用袖珍永磁潘宁源产生毫安级氧负离子束的实验研究。给出了磁场、不同阴极材料及源的离子发射孔对引出氧负离子束的影响。目前,该类型离子源已成功地用于正负氧离子同时加速的1MVISR RFQ加速器上。
The present work concerns in the experimental study on producing mA order of negative oxygen ions with a pocket permanent magnet Penning source. The dependence of negative oxygen ion current on the magnet field, cathode materials and geometry of the source were given. The source was used currently in 1 MV ISR-RFQ accelerator, in which O+ and O- were simultaneously accelerated.
