论文摘要
设计和测量专用的单细胞SIPM结构，以调查暴露于反应堆中子液体的增益和分解电压的辐射损伤影响，最高$φ$ = 5e13 cm $^{ - 2} $。该单元的音高为15 $ $ m。提出了IV曲线的测量和分析结果。研究了自加热效果的影响。检查1个电池和120个电池的辐射损伤均匀性，最多可达$ u_ \ mathit {ov} $ = 1.7 v。从当前测量值$ u^{iv} _ \ mathit {bd} $中提取崩溃电压的通量依赖性$ u^{iv} _ \ mathit {iv} _ $ u^{g} _ \ mathit {bd} $。
A dedicated single-cell SiPM structure is designed and measured to investigate the radiation damage effects on the gain and breakdown voltage of SiPMs exposed to a reactor neutron fluence up to $Φ$ = 5e13 cm$^{-2}$. The cell has a pitch of 15 $μ$m. Results of the measurements and analysis of the IV-curves are presented. Impact of the self-heating effect was investigated. The radiation damage uniformity of 1 cell and 120 cells was checked up to $U_\mathit{ov}$ = 1.7 V. Fluence dependence of the breakdown voltage from the current measurements $U^{IV}_\mathit{bd}$ was extracted and compared to that of the breakdown voltage from the gain measurements $U^{G}_\mathit{bd}$.
