Synchrotron radiation / accelerator / fusion facility

As a national project, we have provided various equipment to a number of scientific experiment facilities promoted by the government. The valuable research results obtained there are fed back to various products.

SPring-8/SACLA

We delivered aluminum bellows for SPring-8 and welded bellows for In-Vacuum Undulator of adjacent X-ray free electron laser (XFEL) facility SACLA.

KEKB (Electron-Positron Collider Facility)

We have delivered a collimator to SuperKEKB, which has been upgraded from KEKB.
A collimator (movable mask) is a device that scrapes halos near the beam trajectory and is used to reduce the background of the particle detector (Belle II).

 

J-PARC (Proton Accelerator Facility)

Big-BPM and Proton Beam Profile Monitor
This device detects the position and profile of the proton beam incident on the J-PARC synchrotron accelerator. Big-BPM consists of a rectangular detector body and a circular vacuum vessel with flanges on both ends covering the outside. In order to make the electrodes a large rectangle and eliminate the influence of pressure, the outer cylinder of the vacuum vessel and the housing that fixes the electrodes are separated.
We researched shield gas conditions and jigs for titanium welding, and developed welding technology with extremely low oxidation.

JT60-SA (Nuclear Fusion Facility)

We have delivered 38 welded bellows that connect PORT and CRYOSTAT connected to the vacuum vessel. Since the material is also special, it was necessary to devise processing, welding, and waving Currently, the National Institutes for Quantum and Radiological Science and Technology has assembled the JT-60SA in March 2nd year of Reiwa through activities that are being carried out jointly with Fusion for Energy (a business entity established by the European Union).
Completed, integrated test operation such as vacuum test, superconducting coil cooling test and energization test is ongoing.
