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").
