Targetry of Y₂O₃ on a copper substrate for the non-carrier-added ⁸⁹Zr production via ⁸⁹Y(p, n)⁸⁹Zr reaction

Abstract

Abstract A thick layer of Yttrium oxide was deposited on cupper substrate via two special sedimentation methods for the production of 89 Zr. For deposition of Y 2 O 3 on cupper substrate, 435 mg of Y 2 O 3 , 152.25 mg of ethyl cellulose and 4 ml of acetone were used to prepare a Y 2 O 3 layer of 11.69 cm 2 . Also, 435 mg of Y 2 O 3 , 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.
