    Graphical Abstract
    • Abstract
  • 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.
