Abstract

A thick layer of Yttrium oxide was deposited on cupper substrate via two special sedimentation methods for the production of 89Zr. For deposition of Y2O3 on cupper substrate, 435 mg of Y2O3, 152.25 mg of ethyl cellulose and 4 ml of acetone were used to prepare a Y2O3 layer of 11.69 cm2. Also, 435 mg of Y2O3, 174 mg of methyl cellulose and 7.25 ml of water were used. The targets were checked by SEM and thermal shock test. The deposited target was irradiated for 20 min at a current of 20 μA and a proton beam of 15 MeV.

Für die Produktion von 89Zr wurde eine dicke Schicht Yttiumoxid auf ein Kupfersubstrat aufgebracht mit Hilfe von zwei speziellen Sedimentationsmethoden. Für das Aufbringen von Y2O3 auf Kupfersubstrat wurden 435 mg Y2O3, 152,25 mg Äthylzellulose und 4 ml Azeton zur Herstellung einer Y2O3 Schicht von 11,69 cm2 verwendet. Ebenso wurden zur Beschichtung 435 mg Y2O3, 174 mg Methylzellulose and 7,25 ml Wasser verwendet. Die Targets wurden überprüft mit SEM und Wärmeschocktests. Das so hergestellte Target wurde 20 min lang bei einem Strom von 20 μA mit einem 15 MeV Protonenstrahl bestrahlt.
