Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Klystrons face challenges in adjusting output balance between ports due to the need to remove the auxiliary magnet and reassemble the klystron structure for impedance adjustments, leading to lengthy lead times.
Innovation Solution
An output adjustment mechanism is introduced, allowing deformation of the output waveguide by using engagement members and jigs without removing the auxiliary magnet, enabling quick adjustment of output balance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the auxiliary magnet is removed and the klystron structure is disassembled for waveguide deformation, then the output balance can be adjusted, but the lead time becomes enormously long
Solution Approach 1:
The auxiliary magnet is divided into multiple segments that can be independently removed and reassembled. This allows the waveguide access portion to be separated without removing the entire auxiliary magnet, enabling quick adjustment of the output waveguide shape while maintaining most of the auxiliary magnet in place, thus reducing lead time significantly
Solution Approach 2:
The auxiliary magnet is pre-divided into separable segments with standardized interfaces during manufacturing. This preliminary segmentation allows for rapid disassembly and reassembly operations during adjustment, eliminating the need for time-consuming custom fabrication or complex disassembly procedures
2Manufacturing precision
If the klystron structure is repeatedly disassembled and reassembled for adjustment and resetting, then the output balance can be optimized, but the productivity decreases due to enormous lead time
Solution Approach 1:
By segmenting the auxiliary magnet, repeated adjustments can be performed by simply removing and repositioning specific segments rather than disassembling the entire structure. This maintains manufacturing precision for output balance matching while dramatically improving productivity through reduced adjustment cycles
Solution Approach 2:
The auxiliary magnet is designed with dynamic, reconfigurable segments that can be easily repositioned during adjustment operations. This dynamic design allows multiple adjustment iterations without the cumulative time penalty of complete disassembly and reassembly, enabling rapid optimization of output balance

AI summary
According to one embodiment, a klystron includes a high-frequency interaction unit, a main magnet arranged in a ring shape around the high-frequency interaction unit, an output waveguide, an auxiliary magnet arranged in a ring shape opposing the output waveguide, an output unit for extracting high-frequency power from the output waveguide, and an output adjustment mechanism which adjusts the output of the high-frequency power extracted from the output unit by deforming the output waveguide. In the output adjustment mechanism, the output waveguide is deformed by engaging a distal end of a jig inserted from an outside of the auxiliary magnet via a jig insertion hole with an engagement member and pushing or pulling the engagement member.
