Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the extraction device is positioned for default operation mode, then beam extraction is optimized for normal conditions, but beam extraction fails or is reduced when radio-frequency cavities fail
Solution Approach 1:
The extraction device is pre-positioned during manufacturing to accommodate multiple failure modes. Beam paths are simulated in advance for various cavity failure scenarios, and the extraction device location is calculated beforehand to ensure it can extract beams even when cavities fail, eliminating the need for complex real-time repositioning.
Solution Approach 2:
The invention changes the positional parameters of the extraction device during the design phase to optimize for reliability. By calculating the extraction device position based on simulated beam paths from multiple failure modes, the system achieves robust performance across different operational conditions without requiring complex adjustments during operation.
2Reliability
If parameter adjustments are made during operation to compensate for cavity failures, then beam extraction can be maintained, but operation time is extended and downtime increases
Solution Approach 1:
The system performs preliminary simulation of beam paths for various failure modes during the manufacturing phase. The extraction device position is pre-calculated to work with multiple failure scenarios, so when a cavity actually fails, no time-consuming parameter adjustments are needed - the pre-configured extraction position immediately handles the failure condition.
3Reliability
If redundant cyclotron systems are implemented to ensure continuous operation, then reliability is improved, but cost and space requirements increase significantly
Solution Approach 1:
The extraction device is designed with multi-functionality to handle both normal operation and multiple failure modes. By positioning the extraction device based on simulated beam paths from various failure scenarios, a single cyclotron system can perform the function of multiple systems - maintaining reliable beam production without requiring redundant cyclotrons, thereby reducing cost and space requirements.

AI summary
A method of manufacturing a cyclotron (10) for producing a beam (18) of accelerated particles comprises the following steps: A cyclotron set-up is defined, the cyclotron set-up including a number of sectors (12) having an RF cavity (14, 16) of the cyclotron (10), an arrangement of the sectors (12) relative to each other and a cavity type for each of the sectors (12) selected from the group comprising acceleration cavities and flattop cavities. Then, a beam path in the cyclotron (10) is determined for a default operation mode and at least one beam path in the cyclotron (10) is determined for a cavity failure mode in which the radio-frequency cavity (14, 16) of one or more of the sectors (12) is not operational. A position of an extraction device (20) of the cyclotron (10) within the sectors (12) is calculated based on the determined beam paths, and the extraction device (20) is placed at the calculated position. Further, a cyclotron (10) and a method for operating a cyclotron (10) is described.
