Neutron radiography data and simulations of aluminium and anodic oxide aluminium for phase filtering

Data for article: "Neutron phase filtering for separating phase- and attenuation signal in aluminium and anodic aluminium oxide"Authors: Estrid Buhl Naver, Okan Yetik, Noémie Ott, Matteo Busi, Pavel Trtik, Luise Theil Kuhn, and Markus Strobl.All data is in the form of grey scale images where high values mean high intensity. Data in folder "Neutron data" are open beam and dark current corrected neutron radiography images. Label "C0um" means pure aluminium with no oxide coating and labels "CMaxTum", "Cmaxum" mean anodic oxide coated aluminium.Neutron data/BOA: Neutron data measured at BOA with different sample-detector distances. Distances specified in file name should have 4.6 mm subtracted.Neutron data/ICON: Neutron data measured at ICON with different neutron wavelengths. Neutron energies are given by time of flight chopper frequency. Frequencies correspond to wavelengths as follows: 119Hz -> 2.7Å, 100Hz -> 3.2Å, 80Hz -> 4Å, 70Hz -> 4.5Å.Data in folder "McStas data" are simulated neutron radiography images. They are not open beam corrected.McStas data/BOA simulations: Neutron data simulated using full BOA instrument with different sample-detector distances. Distances in file name should have 1 mm subtracted. Includes data for pure Al sample (labelled "Al"), data for oxide coated Al sample (labelled "Alcoat"), open beam data (labelled "noAl"), and attenuation only data (labelled "Alabs" and "coatAlabs").McStas data/ICON simulations: Neutron data simulated using simplified ICON instrument with different neutron wavelengths. Includes open beam data (labelled "noAl"), data for pure Al sample (labelled "Al"), data for oxide coated Al sample (labelled "Alcoat"), and attenuation only data (labelled "Alabs" and "Alcoat_abs").

数据集描述：
文章数据：'中子相位滤波分离铝及其阳极氧化铝中的相位与衰减信号'
作者：Estrid Buhl Naver, Okan Yetik, Noémie Ott, Matteo Busi, Pavel Trtik, Luise Theil Kuhn, 及 Markus Strobl。
所有数据均以灰度图像的形式呈现，其中高值代表高强度。'Neutron data' 文件夹中的数据为开束和暗电流校正的中子射线照相图像。标签 'C0um' 表示未涂覆氧化层的纯铝，而标签 'CMaxTum' 和 'Cmaxum' 则代表涂覆了阳极氧化层的铝。
Neutron data/BOA：在 BOA 处测量的中子数据，具有不同的样品-探测器距离。文件名中指定的距离应减去 4.6 毫米。
Neutron data/ICON：在 ICON 处测量的中子数据，具有不同的中子波长。中子能量由飞行时间斩波器频率给出。频率与波长的对应关系如下：119Hz -> 2.7Å，100Hz -> 3.2Å，80Hz -> 4Å，70Hz -> 4.5Å。
'McStas data' 文件夹中的数据为模拟的中子射线照相图像。这些数据未进行开束校正。
McStas data/BOA 模拟：使用完整 BOA 仪器模拟的中子数据，具有不同的样品-探测器距离。文件名中的距离应减去 1 毫米。包括纯铝样品数据（标记为 "Al"），涂覆氧化层铝样品数据（标记为 "Alcoat"），开束数据（标记为 "noAl"），以及仅衰减数据（标记为 "Alabs" 和 "coatAlabs"）。
McStas data/ICON 模拟：使用简化 ICON 仪器模拟的中子数据，具有不同的中子波长。包括开束数据（标记为 "noAl"），纯铝样品数据（标记为 "Al"），涂覆氧化层铝样品数据（标记为 "Alcoat"），以及仅衰减数据（标记为 "Alabs" 和 "Alcoat_abs")。
