Abstract

We strive to develop a 3D coordinate measuring machine, which can measure the inner shape of a cavity with a complex shape. Currently, the ILC (International Linear Collider) project is progressing through international collaboration. The major goal of ILC is to produce and investigate Higgs bosons. ILC consists of two linear accelerators facing each other, and will hurl some 10 billion electrons and positrons toward each other at nearly the speed of light. The cavity is an important component to accelerate particles to near light speed. A cavity’s inner 3D shape influences the accelerating performance. Therefore, it is important to measure the inner 3D shape of a cavity. However, it is difficult to measure the inner shape of cavities with complex shapes like a bellows. We are developing a highly accurate, inner shape measuring machine using triangulation and a measuring method.
