摘要
高压倍加器实验测量厅本底较高,影响实验测量,故需要对实验测量厅的屏蔽进行改进。我们测量分析了实验测量厅的本底情况,通过模拟计算给出了墙面和准直器的改进方案,之后在墙上加石蜡对模拟计算进行了简单的验证测量。在屏蔽体改造完成后进行了铁样品测量,结果显示改进效果良好。
The background of high voltage multiplier hall is high,which effects our experiment.So it is critical to improve the shield of experiment hall.We measured and analyzed the background of experiment hall.By simulation,the article gives the scheme of improving wall and collimator.After adding paraffin beside the wall,we have done a simple validating experiment.The results on Iron target show that the.improvement is very well.
