摘要:

我们使用蒙特卡罗模拟软件包McStas对日本PARC的4SEASONS谱仪的分辨函数进行了模拟。模拟结果表明,通过使用简化的描述,与能量和动量分辨率的分析计算相当吻合。我们在4SEASONS中使用的标准数据分析工具Utsusemi中实现了新功能,以实现模拟分辨率函数的可视化,并预测其在特定实验配置中的形状。

英文摘要:

We performed simulations of the resolution function of the 4SEASONS spectrometer at J-PARC by using the Monte Carlo simulation package McStas. The simulations showed reasonably good agreement with analytical calculations of energy and momentum resolutions by using a simplified description. We implemented new functionalities in Utsusemi, the standard data analysis tool used in 4SEASONS, to enable visualization of the simulated resolution function and predict its shape for specific experimental configurations.
