摘要
用电子顺磁共振和光吸收法研究了1—17MeV^(35)Cl和^(19)F离子注入石英玻璃产生的缺陷的特性,并与2MeV质子注入和0.633MeVγ射线辐照的结果作了比较。观察到MeV重离子轰击下石英表面发生分裂和密度变化现象。对于17MeV^(35)Cl^(+4)离子,注入通量约为1×10^(11)Clcm^(-2)下,体收缩率约为0.36 ％。
The nature of defects in vitreous fused silica induced by implanting with 1-17 MeV 35C1 and 19F ions have been investigated and compared with the results obtained after 2 MeV protons or 0.633 MeV γ-rays irradiation using ESR and optical absorption techniques. The surface cracking caused by MeV heavy ion-bombardment was found. No cracks were seen for 2 MeV protons. The contraction in MeV heavy ion implanted vitreous fused silica was observed. The volume change is about 0.36% at an ion fluence (17MeV 35Cl+4) of 1×1015 35Cl cm-2.
