摘要：Using Technology Computer-Aided Design(TCAD) 3-D simulation,the single event effect(SEE) of 25 nm raised source-drain FinFET is *** on the calibrated 3-D models by process simulation,it is found that the amount of charge collected increases linearly as the linear energy transfer(LET) increases for both n-type and p-type FinFET hits,but the single event transient(SET) pulse width is not linear with the incidence LET and the increasing rate will gradually reduce as the LET *** impacts of wafer thickness on the charge collection are also analyzed,and it is shown that a larger thickness can bring about stronger charge *** reducing the wafer thickness could mitigate the SET effect for FinFET technology.

摘要：Since single event transient pulse quenching can reduce the SET(single event transient) pulsewidths effectively,the charge collected by passive device should be maximized in order to minimize the propagated *** the perspective of the layout and circuit design,the SET pulsewidths can be greatly inhibited by minimizing the layout spacing and signal propagation delay,which sheds new light on the radiation-hardened ICs(integrated circuits) *** show that the SET pulsewidths of propagation are not in direct proportion to the LET(linear energy transfer) of incident particles,thus the defining of the LET threshold should be noted when SET/SEU(single event upset) occurs for the radiation-hardened *** capability of anti-radiation meets the demand when LET is high but some soft errors may occur when LET is ***,radiation experiments should be focused on evaluating the LET that demonstrates the worst response to the circuit.

摘要：为了测试反复启停对钠冷快堆(SFR)一回路主泵推力轴承可靠性和阻力矩的影响,采用适用于小样本的分散系数法设计了可靠性统计方案,制造了3套巴氏合金推力瓦和1台上部组合轴承样机,设计并搭建了试验台,测试了启动阻力矩随停机加载时间的变化情况,模拟推力轴承的真实情况并开展了反复启停试验。试验研究表明,启动阻力矩均会随着停机加载时间的延长而不断增大;反复启停对推力瓦的磨损寿命影响较小,置信度0.9时,推力轴承启停125次不发生失效的可靠度超过0.99996;反复启停会影响推力轴承的阻力矩,随着启动次数的增多,推力轴承的阻力矩呈缓慢上升趋势,证明开展主泵电机启动能力设计时,必须要考虑启停次数的影响。本文研究可为主泵电机启动能力设计提供参考。
