用DRESS验证MAST的中子发射和中子能谱计算
Validation of neutron emission and neutron energy spectrum calculations on MAST with DRESS
摘要：
最近开发的定向相对论光谱模拟器（DRESS）的代码已被验证的第一次对数值计算和MAST上进行的实验测量。在此验证中，由DRESS计算的中子发射率和速率是以TRANSP/NUBEAM预测为基准的，而由DRESS提供的中子能谱作为输入TRANSP/NUBEAM和ASCOT/BBNBI在陀螺轨道（GO）模式下的快离子分布则是以中子通量监测器测量的质子脉冲高度谱（PHS）为基准进行验证的。DRESS和TRANSP/NUBEAM预测的局部和总的中子发射之间的良好协议。
英文摘要：
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.
