Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Synchrotron radiation facilities experience long downtime due to frequent maintenance requirements, leading to excessive down-time of x-ray imaging instruments, which is not addressed by traditional tabletop x-ray sources that can operate continuously.
Innovation Solution
Integration of a tabletop x-ray source into x-ray microscope systems, allowing them to operate as an alternative power source during synchrotron maintenance periods, using beam conditioning systems with optical elements to control collimation and energy filters to match emission characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If synchrotron radiation sources are used for x-ray imaging, then brightness and spectral characteristics are improved, but downtime increases due to frequent maintenance
Solution Approach 1:
The patent combines two different x-ray sources (synchrotron radiation source and tabletop source) into a single imaging system, allowing the system to switch between them. This merging enables the system to utilize the high brightness of synchrotron sources when available and the continuous operation capability of tabletop sources during maintenance periods, thereby resolving the contradiction between brightness and downtime.
Solution Approach 2:
The imaging system is designed to perform multiple functions by supporting both synchrotron radiation-based imaging and tabletop source-based imaging. This multi-functionality allows the system to adapt to different operational conditions, maintaining high brightness when synchrotron is available while ensuring continuous operation during maintenance, thus resolving the downtime issue.
2Loss of time
If tabletop x-ray sources are used for continuous operation, then downtime is reduced, but brightness and spectral characteristics deteriorate
Solution Approach 1:
The system dynamically switches between two different x-ray sources based on operational requirements and availability. When the synchrotron is operational, the system uses it for high brightness imaging; when maintenance is required, it switches to the tabletop source for continuous operation. This dynamic adaptation resolves the contradiction between continuous operation and brightness.
3Loss of time
If different x-ray sources are integrated into a single system, then continuous operation is enabled, but device complexity increases
Solution Approach 1:
The patent introduces beam conditioning systems and optical elements as intermediaries to bridge the two different x-ray sources and the imaging system. These intermediaries adapt the beam characteristics from either source to match the requirements of the imaging system, managing the complexity through standardized interface components while enabling continuous operation.

AI summary
An x-ray imaging system uses a synchrotron radiation beam to acquire x-ray images and at least one integrated x-ray source. The system has an imaging system including sample stage controlled by linear translation stages, objective x-ray lens, and x-ray sensitive detector system, placed on a fixed optical table and a mechanical translation stage system to switch x-ray sources when synchrotron radiation beam is not available.
