Neutron Microtomography of MgB2 Superconducting Multifilament Wire

Publication date: 2017 Source:Physics Procedia, Volume 88 Author(s): Pavel Trtik, Christian Scheuerlein, Patrick Alknes, Michael Meyer, Florian Schmid, Eberhard Lehmann Neutron imaging of sub-10-micrometres spatial resolution has been recently achieved in 2D mode within the framework of the Neutron Microscope project at the Paul Scherrer Institut. Here we report on the development of the PSI Neutron Microscope instrument and the results of the first microtomographic imaging experiment of multifilament superconducting MgB2 wire. The sample of MgB2 superconducting 37 multifilaments embedded in copper-nickel matrix was investigated –in microtomographic mode– with the scientific interest regarding the distribution of boron within the individual superconducting filaments (about 40μm in diameter). The resulting tomographic dataset revealed the distribution of boron within the entire 0.8mm thick multifilamental wire with the isotropic voxel size of 2.6 micrometres.
