Design of Reaction Cavity for a Microwave-assisted Synthesis System
This paper focuses on the microwave assisted synthesis system for the automatic preparation system of positron emission tomography(PET)radiopharmaceuticals.Recently,many microwave assisted chemical synthesis system has been developed,since the system has several advantages such as the reaction acceleration,the enhanced physicochemical properties,and so on.However,most systems are the microwave generation part and the reaction part all-in one then it is hard to apply to the already developed systems,specially,the radio-labeling applications in the limited space of a hot-cell.For the problem,we developed a stand-alone reaction cavity,which is connected to the power controllable magnetron using flexible cable.The cavity is a doughnut-shape and an electric field is radiated through the middle windows of the center hole,to which a vial is inserted.The cavity is simulated using HFSS and the resonance properties are measured using Agilent E8357A network analyzer.The experiment results using a vial with radius of 22mm and height of 38 mm,which is used in the preparation system,show that the water in the vial is heated stably.
