Solution Overview
Problem
The existing particle beam therapy systems face a significant challenge in managing the large amount of pattern data required for synchronizing the high-frequency acceleration cavity and electromagnets, leading to increased data storage needs and communication times, which hampers efficient operation.
Innovation Solution
A charged particle accelerator is designed with a clock generation unit that produces synchronized acceleration cavity and electromagnet clocks with different frequencies, reducing the data amount for the electromagnet patterns and enabling faster communication of pattern data by using a clock generation unit that divides a reference clock to generate the acceleration cavity clock and electromagnet clock.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single clock is used to control both the high-frequency acceleration cavity and the electromagnet, then the system structure is simplified, but the amount of pattern data becomes extremely large and communication time increases
Solution Approach 1:
The patent divides the single clock into two separate clocks: a first clock for the acceleration cavity and a second clock for the electromagnet. This segmentation allows each component to have its own optimized clock frequency, reducing the amount of pattern data that needs to be communicated and processed, thereby decreasing communication time while maintaining system control functionality.
2Measurement precision
If the clock frequency is increased to match the high-frequency acceleration cavity requirements, then the temporal resolution is improved, but the electromagnet cannot respond properly due to its large time constant
Solution Approach 1:
The patent applies different clock frequencies to different components based on their specific requirements. The acceleration cavity uses a high frequency clock for precise temporal control, while the electromagnet uses a lower frequency clock that matches its response characteristics. This local quality approach ensures each component operates at its optimal frequency without compromising overall system reliability.
3Manufacturing precision
If the pattern data is transmitted at high frequency to match the acceleration cavity, then the synchronization precision is improved, but the data amount becomes massive and storage requirements increase
Solution Approach 1:
By segmenting the control system into two independent clock sources, the patent reduces the frequency at which pattern data needs to be transmitted for the electromagnet. This allows the acceleration cavity to maintain high-frequency synchronization while the electromagnet operates at a lower frequency, significantly reducing the total data amount and storage requirements.

AI summary
