The recently developed Directional RElativistic Spectrum Simulator (DRESS) code has been validated for the first time against numerical calculations and experimental measurements performed on MAST. In this validation, the neutron emissivities and rates computed by DRESS are benchmarked against TRANSP/NUBEAM predictions while the neutron energy spectra provided by DRESS taking as input TRANSP/NUBEAM and ASCOT/BBNBI in Gyro-Orbit (GO) mode fast ion distributions are validated against proton pulse height spectra (PHS) measured by the neutron flux monitor. Excellent agreement was found between DRESS and TRANSP/NUBEAM predictions of local and total neutron emission.

使用 DRESS 在 MAST 上验证中子发射和中子能谱计算

最近开发的定向相对论频谱模拟器 (DRESS) 代码首次通过在 MAST 上进行的数值计算和实验测量进行了验证。在此验证中，DRESS 计算的中子发射率和速率以 TRANSP/NUBEAM 预测为基准，而 DRESS 提供的中子能谱以陀螺轨道 (GO) 模式快速离子分布为输入 TRANSP/NUBEAM 和 ASCOT/BBNBI 进行验证中子通量监测器测量的质子脉冲高度谱 (PHS)。在 DRESS 和 TRANSP/NUBEAM 对局部和总中子发射的预测之间发现了极好的一致性。
