title: The new facility for neutron tomography of IPEN-CNEN/SP and its potential to investigate hydrogenous substances.
abstract: A new facility for neutron tomography has been installed at the IEA-R1 nuclear research reactor of IPEN-CNEN/SP. A tomography can be obtained in 400 s and the spatial resolution in the image is 263 μm. The neutron dose per tomography, in the video camera used for image capture, is only 21 μSv, assures very few damages in its CCD sensor. Some selected objects were investigated and the obtained 3D images demonstrate the capability of the facility to investigate hydrogenous substances.
