摘要
Abstract
Dose rate effect is a mandatory examination item for devices used in nuclear events.Pulse laser sources are widely used for dose rate effects simulation.Compared with transient high dose rate gamma source,a traditional dose rate effects simulation facility,the pulse laser source shows several advantages,including stable pulse output,low parasitic electrical field,capable to micro-dimensional irradiation and low cost.However,the adequacy of pulse-laser based simulation of the dose rate effects in microcircuits may be corrupted mainly due to some limitations such as laser radiation shadowing by the metallization,the non-linear absorption in a high intensity range etc.The adequacy and accuracy of pulse laser-dose rate effects simulation should be improved through experimental design and theoretical correction.This paper reviews the fundamental of pulse laser simulation for dose rate effects,presents the factors limiting the adequacy and accuracy of simulations and addresses the approaches to overcome corresponding factors.关键词
