Evaluation of hydrogen gas flow system in DECY - 13 cyclotron

Abstract

Abstract The Center for Accelerator Science and Technology (CAST – BATAN) is developing a cyclotron that eventually will be used for radioisotope production. The cyclotron accelerates charged particles (?−) generated by ion source through circular trajectories up to the desired energy and form proton beams through an extraction system. In the early operational stage, the beam current strongly influenced by the flow speed of hydrogen gas in the head of an ion source, therefore the gas flow performance needs to be characterized. Evaluation have been undertaken which cover component identification, data collection and analysis of the obtained data. The operational data of the opening gas valve is represented by the voltage and flow rate. This evaluation results can be used as a basis or guidance for further construction of the ion source instrumentation control system.
