欧空局单粒子监督器在北京HI-13串列加速器上的单粒子效应校核实验

摘要

为检验北京HI-13串列加速器单粒子效应(SEE)实验能力与数据测量的可靠性,利用束流参数校核系统——欧空局单粒子监督器进行了单粒子效应校核实验.实验使用C、F、Cl、Cu 4种离子辐照单粒子监督器,通过改变入射角度获得了有效LET值在1.8~67.4 MeV·cm2·mg-1之间的单粒子翻转(SEU)截面数据.实验结果与比利时HIF、芬兰RADEF装置上测得的截面数据一致性较好,证实了北京H I-13串列加速器单粒子效应实验束流参数测量的准确性及截面数据测试的可靠性.%In order to test the experimental ability and data reliability of Beijing HI-13 tandem accelerator ,the single event effect (SEE) calibration experiment was carried out using ESA single event upset (SEU ) monitor ,w hich is an international accepted beam diagnosis system .C ,F ,Cl and Cu ions were used in this experiment .The SEU cross-section was measured over an effective LET range of 1.8-67.4 MeV · cm2 · mg -1 by changing the incident angle of ions to vary LET of ions .Experiment data are consistent very well with those by Belgium HIF and Finland RADEF , and this confirms the veracity of the measured beam parameter and reliability of SEE cross-section data on the Beijing HI-13 tandem accelerator .
