Targetry of SrCO3 on a copper substrate by sedimentation method for the cyclotron production no-carrier-added 86Y

Strontium carbonate deposition on copper substrate was carried out by the sedimentation method in order to produce yttrium-86. Natural strontium carbonate thick layer was prepared with 480 mg SrCO3, 220 mg ethyl cellulose, and 7.5 mL acetone. This optimum condition is a result of several repeated experiments with different amount of ethyl cellulose and acetone. Target quality control was done by SEM photomicrograph and thermal shock test. The deposited target was irradiated at 30 mu A current and 15 MeV proton beam for 12 min. (C) 2008 Elsevier Ltd. All rights reserved.
