The concept of a solution target for obtaining the radioisotope 82Sr via the reaction Rb(p, xn)82Sr is propounded. A computational estimate of the main technological parameters of a solution target is made. The 82Sr yield in a solution target is calculated for solutions of certain compounds of rubidium and initial proton energy 70 MeV. It is shown that the highest 82Sr yield 7.44 MBq/(μA·h) in a solution target can be obtained by using a saturated solution of RbF. The solution fl ow rate in the circulation loop of the target allowing the operation of a target without boiling-up in a 100 μA proton beam is obtained for a target solution with RbF. The mass/size parameters of the heat-exchanger allowing the solution to be cooled tothe initial temperature in a single pass are calculated. The infl uence of radiolysis of the proton-irradiatedsolution on the operation of the target is determined. It is shown that on the whole radiolysis of the solution target is not large but does require defi nite efforts to utilize the hydrogen.
