Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for reducing phase errors in superconducting undulators, such as shimming with additional coils, are complex, expensive, and require cooling cycles, inadequately addressing field deviations and complicating the device design.
Innovation Solution
A device with closed superconducting loops arranged around magnetic poles in superconducting undulators, where the loops automatically compensate for field errors by inducing a counteracting magnetic field, allowing for error correction without cooling cycles, using an arrangement of overlapping or adjacent loops to balance pole differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If shimming with additional coils is used to reduce phase errors, then field errors can be compensated, but the device becomes complex and expensive requiring multiple cooling cycles
Solution Approach 1:
The superconducting loop automatically detects and compensates for field errors through self-induced currents without requiring external measurement or control systems. The loop serves both as the error source indicator and the correction mechanism, eliminating the need for complex shimming procedures with additional coils and multiple cooling cycles.
Solution Approach 2:
The invention extracts the correction function from complex external shimming systems and integrates it into a simple superconducting loop that is already part of the undulator structure. By removing the need for additional measurement and control apparatus, the solution significantly reduces device complexity while maintaining phase error correction capability.
2Manufacturing precision
If conventional shimming procedures are used, then field errors can be corrected, but multiple cooling cycles are required which reduces productivity
Solution Approach 1:
The superconducting loop operates continuously during undulator operation, providing real-time compensation for field errors without interruption. The correction action is continuous and automatic, eliminating the need for repeated cooling cycles required by conventional shimming methods, thereby significantly improving productivity.
Solution Approach 2:
The superconducting loop is pre-installed and prepared in the undulator structure before operation. The compensation mechanism is already in place and activated automatically when the undulator operates, eliminating the need for post-installation shimming procedures and multiple cooling cycles, thus improving productivity from the outset.
3Manufacturing precision
If additional superconducting loops are introduced for error compensation, then phase errors can be reduced, but the device complexity increases and space requirements expand
Solution Approach 1:
The superconducting loop serves multiple functions: it acts as both the undulator magnet structure and the error detection/compensation mechanism. This multi-functionality eliminates the need for separate correction coils and associated control systems, reducing space requirements while maintaining phase error correction capability.
Solution Approach 2:
The invention merges the undulator magnet structure with the error compensation mechanism into a single integrated superconducting loop system. By combining these functions into one component rather than using separate elements, the solution reduces the overall space requirements and simplifies the device structure.
