Abstract

Abstract The purpose of this paper is to present the Monte-Carlo calculations performed to design a special element called gamma blocker (GB), necessary to stop the gamma radiation in the Accelerator-to-Target (A2T) section of European Spallation Source (ESS) linac. Very high levels of gamma radiation emitted backward from the activated target through the beam pipe could effectively block any human intervention close to the beam transport system. The residual dose rate in the linac tunnel was calculated without and with different GBs as a function of time. The final GB material and dimensions are proposed.

欧洲散裂源高能束输运区的伽马辐射计算和伽马阻断器设计

摘要:本文的目的是通过蒙特卡罗计算来设计一种特殊的伽马阻滞剂(GB)元件，该元件用于阻止欧洲散裂源(ESS)直线加速器到目标(A2T)部分的伽马辐射。从被激活的目标通过束流管向后发射的非常高水平的伽马辐射可以有效地阻止靠近束流传输系统的任何人为干预。计算了不含和含不同gb时直线通道内的剩余剂量率随时间的变化。提出了最终的国标材料和尺寸。
