Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional target design is used, then target structure is simple, but cooling efficiency is low and heat transfer area is insufficient
Solution Approach 1:
The target is divided into a pair of target modules arranged in a Y-shape configuration, where each module can be independently cooled and managed. This segmentation increases the total heat transfer area while maintaining manageable structural complexity through modular design.
Solution Approach 2:
The target modules are arranged at specific angles (first angle to each other, second angle to beam direction) in three-dimensional space, creating a Y-shaped configuration that maximizes heat transfer area by utilizing spatial dimensions rather than simply expanding the target surface in one plane.
2Productivity
If high-power particle beam irradiation is applied, then neutron yield increases, but excessive heating occurs
Solution Approach 1:
By dividing the target into two separate modules, the heat load from high-power particle beam irradiation is distributed across both modules rather than concentrated in one, preventing excessive heating while maintaining high neutron yield through continued high-power irradiation.
Solution Approach 2:
The target modules are designed to rotate around an axis perpendicular to the beam direction, dynamically adjusting their orientation to optimize heat distribution and cooling efficiency during high-power irradiation, preventing localized overheating while maintaining neutron production.
3Ease of operation
If conventional target design is used, then target replacement is simple, but target replacement becomes difficult with high-power beams
Solution Approach 1:
The segmented modular design allows individual target modules to be replaced independently if needed, and the modules can be handled at lower temperatures between irradiation cycles, making replacement feasible even in high-power applications where continuous operation would cause excessive heating.
Solution Approach 2:
The rotating target modules operate in periodic cycles of irradiation and cooling, allowing the target to be replaced during cooling periods when temperature is manageable, thus maintaining ease of operation despite high-power irradiation requirements.
