Preparation of Ag Target for Producing ~(109)Cd by Electro-Deposition

The preparation of the Ag target for producing ~(109)Cd by cyclotron using electro-deposition method is described. The effects of main process parameters on the performance and mass thickness of Ag target were studied,and suggested technological conditions are as follows: ρ(Ag~+)=20~50g/L,ρ(KNO_3)=10~30g/L,φ(NH_4OH)=0.1~0.2.By means of it,a well satisfied smooth and firm Ag target with a mass thickness of more than 100mg/cm~2 can be prepared.
