Neutron tomography of petrified wood

The data set contains the projections a piece of petrified wood produced during a neutron CT scan. The purpose of the data is to provide a training data set for users of the open source CT reconstruction software MuhRec https://github.com/neutronimaging/imagingsuite. The data was acquired in 2008 at the cold neutron imaging beamline ICON at Paul Scherrer Institute. The beamline has a collimation in the order of L/D=400 which provides an essentially parallel beam. The setup used an ANDOR DV434 camera with a Pentax 50mm f/1.2 lens and a 100um 6LiF/ZnS scintillator. The pixel size of the projections is 158um. The original data has been cropped (to reduce data size) and converted from the camera file format fits into tiff.
