Data for: Experiment and MCNP simulation of a portable tagged neutron inspection system for detection of explosives in a concrete wall

The contents of these data are as follows:
Fig.3. Comparison of TNT simulation spectrum for different models. The black line is the case where the generator shell material copper is placed in front of the neutron source in the model. The red line is the case where the neutron generator shell material is not placed in the model.
Fig.4. Comparison of simulated and experimental spectra of graphite (a), TNT (b) and ammonium nitrate (c), in the absence of a wall, the samples to be measured are placed in the air alone.
Fig.5. Comparison of simulated and experimental spectrum of TNT inside different thickness walls (a: 10 cm wall + TNT, b: 15 cm wall + TNT, c: 20 cm wall + TNT).
Fig.6. Comparison of simulated and experimental spectrum of ammonium nitrate (AN) inside different thickness walls (a: 10 cm wall + AN, b: 15 cm wall + AN, c: 20 cm wall + AN).

本数据集内容如下：
图3：不同模型下TNT（三硝基甲苯，Trinitrotoluene）模拟能谱对比。其中黑线对应模型中将中子发生器壳体材料铜置于中子源前方的场景；红线对应模型中未设置中子发生器壳体材料的场景。
图4：石墨(a)、TNT(b)与硝酸铵(c)的模拟能谱与实验能谱对比，实验条件为无屏蔽壁，待测样品单独置于空气中。
图5：不同厚度屏蔽壁包裹下TNT的模拟能谱与实验能谱对比，其中(a)为10cm屏蔽壁+TNT，(b)为15cm屏蔽壁+TNT，(c)为20cm屏蔽壁+TNT。
图6：不同厚度屏蔽壁包裹下硝酸铵(ammonium nitrate, AN)的模拟能谱与实验能谱对比，其中(a)为10cm屏蔽壁+AN，(b)为15cm屏蔽壁+AN，(c)为20cm屏蔽壁+AN。
