Segmented Accelerating Cavity Assembly for Machinable Nose Cones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manufacturing techniques for accelerating cavities with protrusions, such as nose cones, are cumbersome and lack ease of assembly.
Innovation Solution
The accelerating cavity is formed by joining multiple part members with planar parting surfaces along a central axis, featuring cells connected by a communicating portion and protrusions that expand radially from a tip end to a base end, allowing for ease of manufacturing through machining and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the accelerating cavity is manufactured by forming multiple part members and joining them, then the ease of manufacture is improved, but the device complexity increases
Solution Approach 1:
The accelerating cavity is divided into multiple part members that are joined together to form the complete structure. This segmentation allows each part to be manufactured separately using standard machining processes, improving ease of manufacture while the modular assembly maintains manageable device complexity
Solution Approach 2:
The part members are prepared in advance with predetermined shapes and dimensions through machining operations. By performing preliminary actions of forming and preparing components before assembly, the manufacturing process becomes more efficient and the ease of manufacture is improved
2Ease of manufacture
If the protrusion has a shape becoming larger in the radial direction from tip to base, then the ease of machining is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The protrusion is designed with a curved surface that becomes larger in the radial direction from the tip toward the base. This curved geometry is easier to machine using standard turning operations compared to flat or angular surfaces, improving ease of machining while the smooth curvature helps maintain manufacturing precision by avoiding sharp corners and discontinuities

AI summary
An accelerating cavity includes: a housing that is conductive, has a tubular shape, and is formed by joining a plurality of part members parted by a planar parting surface along a central axis; a plurality of cells that are arranged in the housing along an axial direction of the central axis of the housing, and are connected to each other by a communicating portion that allows charged particles to pass through; and a protrusion that is disposed at a position surrounding the communicating portion of each of the cells in the housing, protrudes toward an inner side of the cell in the axial direction, and has a shape becoming larger in a radial direction with respect to the central axis from a tip end portion toward a base end portion in the axial direction.
