Natural and enriched tungsten as target for heavy ion experiments

Tungsten is applied as target material for experiments in the field of nuclear spectroscopy. Typically, targets of a thickness range of 100 µg/cm² up to 1000 µg/cm² that can safely stand the irradiation by the intense heavy-ion beam over a substantially long period are requested. Natural tungsten is commercially available as thick foils and as sputtering targets. Enriched tungsten is typically available as metal powder. We report on the production of natural and enriched tungsten targets on carbon backing. We compare the different production processes, taking into account the material yield.
