Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray sources and S-band accelerators are either limited by low energy and large size, or they fail to meet the requirements for high-precision non-destructive testing due to large focus and weight, which is a challenge in applications like industrial CT and vehicle-mounted security inspection.
Innovation Solution
An X-band small-focus accelerator is designed with an X-band accelerating tube, a compact microwave system, and a miniaturized circulator, along with integrated electron gun power supply and collimator control, arranged in a specific sequence to minimize dimensions and weight, while maintaining high energy output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If an S-band accelerating tube is used, then the accelerator can generate high-energy X-rays with strong penetrating power, but the focal size becomes large (1.5-2 mm) and spatial resolution decreases
Solution Approach 1:
The patent changes the microwave frequency parameter from S-band (3 GHz) to X-band (10 GHz), which enables the accelerating tube to achieve both high energy output and small focal size (≤0.5 mm), resolving the contradiction between power and manufacturing precision
2Power
If an S-band accelerating tube is used, then the accelerator can detect large work-pieces, but the accelerator head becomes large in size and weight
Solution Approach 1:
By switching from S-band to X-band frequency, the patent achieves high energy output with a compact accelerator head design, reducing both size and weight while maintaining the capability to detect large work-pieces
Solution Approach 2:
The patent transitions from conventional S-band technology to X-band technology, representing a dimensional change in the frequency spectrum that enables miniaturization while preserving high energy capabilities
3Manufacturing precision
If an X-ray tube is used, then the focal size can be small (below 0.5 mm) improving spatial resolution, but the X-ray energy becomes low and radiation penetration is weak
Solution Approach 1:
The patent merges the advantages of both X-ray tubes (small focal size) and S-band accelerators (high energy) by using an X-band accelerating tube, achieving both ≤0.5 mm focal size and high energy output capable of penetrating large work-pieces
