Beschreibung
Zusammenfassung:	Procedimiento para la producción de convertidores de neutrones, en el que un sustrato metálico transparente a los neutrones de aluminio o de una aleación de aluminio se pule mediante lijado fino en una primera etapa y, en una segunda etapa, se recubre con carburo de boro mediante pulverización catódica. 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 in a further step by means of sputtering with boron carbide or a boron film. An adhesion promoting layer is optionally applied between the metal substrate and below the boron or boron carbide layer. The coatings obtained have a high homogeneity in layer thickness, chemical composition and isotope ratio as well as a low level of impurities such as oxygen or nitrogen.
