Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional injection lines with multiple separate resonant cavities are used, then beam intensity can be achieved, but the device becomes bulky and complex
Solution Approach 1:
The patent merges multiple resonant cavities into a single integrated structure where the first resonant cavity handles first harmonic operations and the second resonant cavity handles second harmonic operations. This consolidation reduces the overall device footprint and structural complexity while maintaining the capability to produce high-intensity beams through multiple injection paths.
Solution Approach 2:
The injection line is designed with multi-functional capability to handle both first harmonic and second harmonic operations within a single system. The resonant cavities are configured to perform multiple functions - grouping ions, controlling beam intensity, and enabling multiple injection paths - thereby reducing the need for separate dedicated components for each function.
2Quantity of substance
If multiple separate resonant cavities are used for different injection paths, then beam intensity is improved, but the physical size and compactness are compromised
Solution Approach 1:
Multiple resonant cavities are merged into an integrated structure that accommodates both first harmonic and second harmonic operations. The cavities are arranged to share common components and space, significantly reducing the overall volume required for the injection line while maintaining the multi-path injection capability for high-intensity beam production.
3Quantity of substance
If conventional injection lines are used, then basic ion injection is achieved, but reliability and intensity control are insufficient
Solution Approach 1:
The injection line incorporates feedback mechanisms through the resonant cavities that can detect and respond to beam conditions. The cavities are designed with tuning capabilities that allow real-time adjustment to maintain optimal operating conditions, thereby improving reliability and consistency of beam intensity control.
Solution Approach 2:
The system utilizes parameter changes in the resonant cavity frequencies and coupling coefficients to control beam intensity and maintain reliability. By dynamically adjusting these parameters, the injection line can adapt to varying operational requirements and maintain stable, high-intensity beam production.

Function Achieved in This Case
The solution results in a compact, reliable injection line capable of producing high-intensity charged particle beams, suitable for various accelerating cavities, with enhanced reliability and flexibility in beam intensity control.
Implementation Method 1
a first harmonic resonant cavity, comprising an enclosure and at least two sliding tubes each associated with a respective source, these sliding tubes being arranged in the enclosure, electrically connected to each other and connected by a conductor to the enclosure, second harmonic resonant cavities, each associated with a respective ion source
Implementation Method 2
the conductor of the first harmonic resonant cavity is quarter wave. Such a length proves to be well suited in that it allows the driver to perform substantially a complete turn around the sliding tubes
Implementation Method 3
The injection line comprising a high frequency power supply connected to the second harmonic resonant cavity, this power supply can be controlled so as to vary the intensity of the ion beam leaving this cavity by varying the phase of the current excitation of this cavity
