Beschreibung
Zusammenfassung:	The present invention relates to a method for producing a neutron converter from boron carbide or a boron film on a neutron-transparent metal substrate. The neutron-transparent metal substrate is polished in a first step by fine grinding and coated with a boron carbide or a boron film in a further step by means of sputtering (cathode sputtering). If appropriate, an adhesion-promoter layer is applied between the metal substrate and the boron or boron-carbide layer. The coatings obtained have a high degree of homogeneity in terms of layer thickness, chemical composition and isotopic ratio and also low levels of impurities such as oxygen or nitrogen.
