Optimization of the beam geometry for the cold neutron tomography facility at the new neutron source in Munich.
One of the very interesting applications at Munich's New Neutron Source will be neutron tomography. It will be used both for research and industry. The D2O moderated high flux reactor will provide thermal neutrons for the structural analysis of specimen up to the size of 1 m. A central problem is the design of the beam geometry, especially the layout of the collimator and the aperture. Calculations were carried out in order to get an optimal beam geometry, taking into consideration an extended source, low beam divergency and high flux in the detector plane.
