Neutron Reflectometer with Polarization Option at the Budapest Neutron Centre

The ever increasing need for product advancement and miniaturization keeps thin film assemblies, membranes, magnetic and non-magnetic multilayer and patterned heterostructures in the limelight of material science and technological development. A number of thin film and surface characterization methods have emerged recently to meet the new challenges. The increased interest in magnetic thin film analytical instruments - mainly triggered by the discovery of the giant magnetoresistance and related phenomena1 - resulted in a boom of PNR studies as well as of the construction of a number of new neutron reflectometers with polarization option at neutron sources all over the world. Here we report on the design, construction and operation parameters and first example uses of the "Grazing Incidence Neutron Apparatus" (GINA) a recently installed neutron reflectometer at the Budapest Neutron Centre (BNC), Hungary.
