Based on the cyclotron theory and virtual prototyping technique, a compact cyclotron virtual prototyping system (CCVPS) is formulated, which implements the innovative design of the cyclotron and avoids risks mostly. The framework of CCVPS takes into account the needs of manufacture, assembly/disassembly, operation, and maintenance in a virtual environment during the design phase. In order to guarantee the reliability of CCVPS, Augmented Reality (AR) technique is used to integrate the virtual environment and experimental subsystem. The overall lifecycle models of the compact cyclotron via CAD system are described in this paper, including cyclotron virtual design, modelling, virtual assemble/disassemble, virtual manufacture, virtual commissioning, virtual operation, virtual maintenance, and other relevant domains. Visualization aspects of 3-dimension models with physical information provide a new orientation on R & D of compact cyclotron from the overall lifecycle models.
