The cathode holder disk of the ion source of the HI-13 tandem accelerator

Caption

The cathode holder disk is part of the NEC multi-cathode source of negative ions by cesium sputtering. Cathodes of 60Fe samples and blank samples were installed on the holder disk.

Researchers at the China Institute of Atomic Energy (CIAE) have significantly enhanced the method of detecting iron-60 (60Fe), a rare isotope found in lunar samples, using the HI-13 tandem accelerator. This achievement paves the way of detecting 60Fe in lunar samples for a deeper understanding of cosmic events like supernovae that occurred millions of years ago. https://doi.org/10.1007/s41365-024-01453-x
