| 摘 要： | HI－13串列加速器升级工程中的在线同位素分离器(ISOL)高质量分辨谱仪要求20000的质量分辨率。本工作采用大小铁双能量结构削弱能量色散，有效解决了束流能散过大导致的谱仪质量分辨率低的问题。结果表明：当束流高斯分布宽度为0.06mm和10mrad时，谱仪的质量分辨率达到了33400；若考虑加速段引入的0.002%能散，谱仪最终的质量分辨率为20000。

| Abstract: | High mass resolution spectrometer for isotope seperator on line(ISOL) in(Beijing) radioactive ion-beam facilities(BRIF) project requires mass resolving power of(20 000).A bi-energy system with big and small dipoles is used to reduce energy dispersion which is too large to get mass resolving power.When the width of beam with a Gaussian distribution is 0.06 mm and 10 mrad,resolving power of this spectrometer is 33 400.After consideration of 0.002% energy spread introduced by acceleration,the final resolving power of this spectrometer reaches 20 000. |
