我们报告了潘宁阱质谱装置 TRIGA-TRAP 与研究反应堆 TRIGA Mainz 的成功耦合。这提供了对位于反应堆堆芯附近的 235 U 目标的中子诱发裂变中产生的短寿命核进行直接高精度质量测量的可能性。基于气溶胶的气体喷射系统用于将短寿命的富中子核从靶室有效传输到表面离子源。结合新的离子光学器件和扩展束流监控功能，实验装置已全面投入使用。介绍了表面离子源的设计、效率研究和初步结果。
We report on the successful coupling of the Penning-trap mass spectrometry setup TRIGA-TRAP to the research reactor TRIGA Mainz. This offers the possibility to perform direct high-precision mass measurements of short-lived nuclei produced in neutron-induced fission of a 235 U target located near the reactor core. An aerosol-based gas-jet system is used for efficient transport of short-lived neutron-rich nuclei from the target chamber to a surface ion source. In conjunction with new ion optics and extended beam monitoring capabilities, the experimental setup has been fully commissioned. The design of the surface ion source, efficiency studies and first results are presented.
