Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current undulator systems face challenges with precision alignment, structural support, and magnetic field management, leading to bulky, expensive, and less precise devices that struggle to achieve high-intensity radiation with precise control over radiation energy and polarization.
Innovation Solution
A force-compensated undulator device is introduced, featuring a first magnet array translatable along a central axis, a second magnet array with a fixed gap, and a compensator unit with translatable magnets to neutralize magnetic forces. This design maintains a precise gap profile and reduces mechanical stresses, allowing for more compact, lightweight, and cost-effective undulators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional undulator systems use fixed magnet arrays with large mechanical support structures, then structural stability is maintained, but device size becomes bulky and manufacturing cost increases
Solution Approach 1:
The patent applies dynamics by making the first magnet array translatable along the central axis, allowing dynamic adjustment of the undulator gap. This replaces static, bulky support structures with a dynamic system that maintains structural stability through controlled motion rather than excessive mechanical rigidity, thereby reducing overall device volume while preserving reliability
Solution Approach 2:
The compensator unit with its second row of magnets acts as a counterweight system that generates opposing magnetic forces to balance the forces from the first magnet array. This force compensation allows the use of lighter mechanical support structures instead of heavy, bulky frameworks, reducing device volume while maintaining structural stability through force equilibrium
2Device complexity
If traditional undulators lack force compensation, then device complexity is reduced, but magnetic forces cause mechanical deformation and reduce alignment precision
Solution Approach 1:
The compensator unit serves as an intermediary system that mediates the magnetic forces between the first magnet array and the mechanical structure. By introducing this intermediate force-compensation layer, the patent prevents direct transmission of large magnetic forces to the mechanical structure, thereby maintaining alignment precision without requiring overly complex reinforcement structures
Solution Approach 2:
The compensator unit applies preliminary counteracting magnetic forces before the main magnetic field forces can cause mechanical deformation. By pre-establishing force balance through the compensator magnets, the system prevents alignment errors from occurring in the first place, maintaining manufacturing precision without adding excessive structural complexity
3Adaptability or versatility
If adjustable gap undulators are used to control radiation energy, then adaptability improves, but mechanical stresses increase and require heavier support structures
Solution Approach 1:
The compensator unit provides counterbalancing magnetic forces that offset the forces generated during gap adjustment for energy control. This allows the undulator to achieve full adaptability in radiation energy control through gap adjustment without experiencing net excessive mechanical forces, eliminating the need for heavier support structures
Solution Approach 2:
The translatable first magnet array enables dynamic gap adjustment for energy control, while the compensator unit dynamically balances the resulting forces. This dynamic force compensation system allows full adaptability in energy control without the magnetic forces accumulating to levels that would require heavier, less adaptable support structures
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The force-compensated undulator achieves precise control over radiation energy and polarization, maintaining a gap profile tolerance of less than 10 microns and reducing mechanical stresses, which enables the fabrication of more precise, compact, and cost-effective undulators.
Implementation Method 1
the compensator unit provides a magnetic force in opposition to a magnetic force between the first and second magnet arrays, such that a net magnetic force is neutralized
Implementation Method 2
Undulators serve as the primary source of radiation... An undulator is a magnetic device that consists of a periodic arrangement of magnets or magnetic fields

AI summary
Employing undulator devices as x-ray radiation sources requires expensive and bulky support systems for operation, which are not robust and lead to limited ranges of generated radiation energies. A force-compensated undulator device is described. The device includes an undulator having first and second magnet arrays disposed along a central axis. The first magnet array is translatable along the central axis. The device further includes a compensator unit disposed adjacent to the first magnet array with the compensator unit having a first row of magnets disposed along a compensator axis with the compensator axis being parallel to the central axis, and a second row of magnets disposed along the compensator axis. The first row of magnets is translatable along the compensator axis. The compensator provides magnetic forces that neutralize the system dynamic magnetic forces generated by the undulator.
