Description
A cyclotron dedicated to the production of the radio-pharmaceutical Astatine-211 (211At) has been designed. This cyclotron employs an external injection system to introduce alpha particles, utilizing a four straight-sector magnet design and a dual radio-frequency (RF) cavity configuration to accelerate the alpha particles to an energy of 30 MeV. The beam is then extracted from the cyclotron via an electrostatic deflector (ESD). This paper presents an overview of its primary parameters. It subsequently provides a detailed description of magnet systems. Furthermore, extensive beam dynamics simulations are performed. The particle trajectory is tracked through the entire acceleration process to the final extraction, with evaluation of the beam transverse profile, confirming the design’s capability to deliver a high-intensity beam suitable for medical isotope production.
