| 摘 要： | 基于硬件补偿-屏蔽法,提出了一种简单确定碘化钠探测器铅补偿体尺寸的方法,可简化试验以及模拟方面的工作。该方法结合探测器的原始能响和铅补偿体的空隙率-厚度曲线,可便捷地得到补偿体尺寸的参考值,进而通过适当调整空隙率-厚度值来确定最佳铅补偿体的尺寸。

A Simulation Research of Energy Response Compensation for NaI Detector |
| |
| Abstract: | Based on hardware compensation-shielding method, a simple way to compensate the energy response of NaI detector using lead shield was introduced in this work.The right shape and size of lead shield can be determined simply, which can shorten the test cycle and simplify the simulation calculation process.By combining the original energy response of NaI detector with the relation between porosity and thickness of lead shield, a reference value of lead shield's size can be obtained easily.And then, the fittest shape and size of lead shield can be found by some necessary verification work. |
