NEURON has been working on research development for next generation.

We would like to introduce our development project which we have got a fixed evaluation in the manufacture of ILC *1 accelerator cavity with utilizing EBW (Electron beam welding machine).

◇1 cell cavity electric performance test

Joint venture with High Energy Accelerator Research Organization

Supplied a beam pipe*2 of penetration welding by using our own EBW.

Nb(niobium) material which is very difficult to weld due to its high melting point.

The standard of the acceleration gradient is *3 35MV/m, but we have got the maximum acceleration gradient 37MV/m

as a good evaluation in the electric performance test.

*1. The International Linear Collider (ILC) is a positron collision type accelerator which the three area of Asia,

North America and Europe proposes in cooperation with each other.

The purpose is to figure out the mystery about the creation of the space by reproducing the state soon after the big bang.

In addition, it is expected a variety of ripple effects of advanced technology from the research development.

*2. Beam pipe – A pipe which electron and positron pass through.

*3. Acceleration gradient – “acceleration” of particle means both of increasing the speed and energy.

The acceleration gradient means how the accelerator can increase the energy of particle in a certain distance.

The higher the acceleration gradient is, the shorter the linear accelerator becomes.
