Abstract Time, energy, and angle correlated neutrons are emitted in nuclear fission. New, physics-based fission event generators that capture these correlations have been incorporated into MCNP6.2 because correlations can impact nuclear non-proliferation and safeguards systems response. DRiFT is a detector response code that takes MCNP outputs and reproduces laboratory analogous detector quantities. Previous work has compared DRiFT to single detector experiment data and has discussed recent updates to DRiFT specific to correlated fission experiments. This work shows a validation of recent updates to DRiFT for organic scintillator response in correlated fission neutron experiments using a 252Cf source. Outputs from MCNP with the FREYA fission event generator were post-processed with DRiFT and compared to experiment data. Simulation and experiment results are in reasonably good agreement for multiple correlated neutron quantities.

用 MCNP 和相关包对相关中子的闪烁体探测器响应进行实验验证

摘要 核裂变中释放出时间、能量和角度相关的中子。捕获这些相关性的新的基于物理的裂变事件发生器已被纳入 MCNP6.2，因为相关性会影响核不扩散和保障系统响应。DRiFT 是一个探测器响应代码，它采用 MCNP 输出并再现实验室模拟探测器数量。以前的工作将 DRiFT 与单探测器实验数据进行了比较，并讨论了最近针对相关裂变实验的 DRiFT 更新。这项工作显示了对使用 252Cf 源的相关裂变中子实验中有机闪烁体响应 DRiFT 的最新更新的验证。带有 FREYA 裂变事件发生器的 MCNP 的输出使用 DRiFT 进行后处理，并与实验数据进行比较。
