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.
In order to increase a capacity building of an accelerator development, Center for Accelerator Science and Technology (CAST) - BATAN Yogyakarta, is developing DECY-13 Cyclotron for Positron Emission Tomography (PET) radioisotope production. One of the main components of the cyclotron, a magnet has been designed based on equilibrium orbits analysis of each increase in energy. To assure the designed magnet can guide a particle up to 13 MeV, a particle tracking is important to be carried out using simulation codes that have been benchmarked. Here, the designed magnetic field data and electric field data of the Dee were used in particle tracking simulation. The particle tracking results show that particles in the pass acceptance range can pass the central region and be accelerated up to 13 MeV. These results are consistent with the previous result of our particle tracking code. The range of phase acceptance of accelerated particle is around 110 degrees and the maximum initial axial excursion of the accelerated particles is + 1.5 mm. These results verify that the designed magnet can guide particles up to 13 MeV.
A cyclotron is a machine that accelerates a charged particle in a circular trajectory using electric and magnetic fields. The technical development of 13 MeV cyclotron in PSTA (Pusat Sains dan Teknologi Akselerator) BATAN was started in 2010 which eventually will be used for radioisotope production. A cyclotron consists of various technologies such as an electromagnetic, RF (Radio Frequency), ion source, and vacuum systems. Among them, the electromagnetic creates a magnetic field for particles to accelerate in a stable circular orbit. A particle within a uniform magnetic field moves along a closed trajectory, and that is called an equilibrium orbit. The stability of particle acceleration refers to the movement along the equilibrium orbit with oscillation. This paper deals with the equilibrium orbit verification using CYCLONE. We calculated and analyzed the magnetic and electric fields using Opera, then used them as input data in CYCLONE. The CYCLONE analysis provides several beam parameters such as beam energy, tune diagram, and beam trajectory. The analysis result shows that the beam was accelerated until the desired energy (13 MeV).
