论文摘要
除了感兴趣的同位素外，许多用于创建核研究产生放射性同位素的核反应，许多污染物通常产生的量比感兴趣的同位素大得多。因此，许多使用ISH方法的装置配备了高分辨率质量分离器，以删除具有不同质量数的同位素。在本文中，我们介绍了目前在LP2I波尔多（以前是CENBG）开发的Desir HRS的结果。光学畸变最多可校正第三阶，并在25 keV处的133CS+梁的传输达到了M/$δ$ 225000的质量分辨率，约为70％。
Many nuclear reactions used to create radioactive isotopes for nuclear research produce, in addition to the isotope of interest, many contaminants, which are often produced in much larger amounts than the isotope of interest. Many installations using the ISOL approach are therefore equipped with high-resolution mass separators to remove at least isotopes with a different mass number. In the present paper, we present the results of the commissioning of the DESIR HRS presently under development at LP2I Bordeaux (formerly CENBG). Optical aberrations are corrected up to 3rd order and a mass resolution of M/$Δ$M of 25000 is reached with a transmission of about 70% for a 133Cs+ beam at 25 keV.
