摘要

中国科学院高能物理研究所提出了ERL-FEL （Energy recovery linac-Free electron laser）“一机两用”的概念，通过同一直线加速器将能量回收加速器（Energy recovery linac

ERL）和自由电子激光（Free electron laser

FEL）结合到一起。本文讨论ERL-FEL两用实验装置主体屏蔽设计中，利用离散抽样的方法实现多个损失源项的整合，在同一FLUKA用户程序中实现多源抽样，并将蒙特卡罗计算结果与各源项独立处理的累积结果进行对比。计算表明，两者的结果吻合较好。基于束流损失源项整体建模的方法适用于其他小型直线加速器的整体屏蔽计算，可方便在其他装置上扩展应用。

Abstract

Background:

The study of the ERL-FEL (Energy recovery

linac-Free electron laser) is in progress at IHEP (Institute of High Energy Physics). It's necessary to shield the radiation of the ERL-FEL.

Purpose:

This thesis mainly discusses how to use FLUKA to write the source file of the ERL-FEL to optimize shielding design.

Methods:

The discrete sampling method was used to integrate multiple lost sources in one source file and a comparison was made between the whole source simulation results and the accumulative total of all the independent source processing results.

Results:

The result shows that they are exactly similar.

Conclusion:

The discrete sampling method based on the beam loss source is suitable for the small electron linear accelerator shielding calculation

and it's also conducive to the expansion of the user program source in different devices.
