A pulsed laser has been effectively applied in dose rate effects simulation for its stable pulse output, low cost, simple operation, and lack of ionizing risks for users. The conversion factor (CF) was proposed to describe the equivalence between the responses generated by pulsed laser and pulsed ionizing radiation (e.g., γ\gamma -ray). Previously, the peak photocurrent was commonly used to calculate the CF and establish the equivalent relationship. But there are a number of shortcomings such as narrow effective equivalent range, inadequate information of waveform, as well as low accuracy of simulations. In this article, an improved method for obtaining the CF by using the charge collection as the equivalent factor is proposed, which considers not only the peak photocurrent but also the temporal information of the waveform. The advantages of the proposed method are proved both in theory and in experiments, including broader equivalent range and higher simulation accuracy.

一种具有改进性能的激光模拟剂量率效应的电荷收集等效方法


脉冲激光器以其脉冲输出稳定、成本低廉、操作简单、用户无电离风险等优点，在剂量率效应模拟中得到了有效的应用。提出转换因子（CF）来描述脉冲激光和脉冲电离辐射（例如γ\gamma射线）产生的响应之间的等效性。以前，通常使用峰值光电流来计算CF并建立等效关系。但存在有效等效范围窄、波形信息不充分、仿真精度不高等缺点。本文提出了一种以电荷收集为等效因子来获取CF的改进方法，该方法不仅考虑了峰值光电流，还考虑了波形的时间信息。该方法的优点在理论和实验上均得到证明，包括更宽的等效范围和更高的模拟精度。
