Engineering

Achievement of an integrated production system beginning with design

Metal Technology Co. Ltd.’s Engineering Division is responsible for the design phase. Based on the customer’s requirements, the engineer designs and verifies the validity of the design through FEM analysis, mock-up tests, etc. in order to complete the design ready for manufacturing. After that, MTC completes the manufacturing of the product by making full use of various manufacturing technologies (material selection, machining, heat treatment / surface treatment, bonding, etc.) tailored to the needs of the design.

【Achievements】
Metal Technology Co. Ltd.’s Engineering Division has been an integral part in the development and installation of critical parts for Japan’s nuclear research institutes with regards to particle acceleration. MTC is also a key player in the development of nuclear fusion technology. This includes neutron experiments at the Japan Proton Accelerator Research Complex (J-PARC), the world's largest fusion experiment, the ITER project, and experience manufacturing equipment used for the XMASS experiment for university funded research.

Achievement of integrated production system participating from the designing stage

Integration of technology and know-how

The Engineering Division is the center of engineering activities at MTC, coordinating and closely cooperating with all of MTC’s plants. Each plant has specific manufacturing strengths in a variety of areas that complement one another. This allows MTC to perfectly match our customer’s needs. MTC believes that products manufactured in such a manner will contribute to society by meeting our customers’ requests whilst utilizing accumulated know-how to best utilize resources and reduce waste.

An example of an accelerator

Product name: Collision point (interaction region) beam pipe for SuperKEKB

Product name: Collision point (interaction region) beam pipe for SuperKEKB

Product details

The beam pipe is a vacuum chamber with a complicated structure that is used as part of the SuperKEKB, a gigantic accelerator leading the physics experiments in elementary particles in Japan. The SuperKEKB is a colliding-beam accelerator and the beam pipe manufactured by MTC is installed at the most important section of it, (add: the interaction region (IR)) where electrons and positrons collide frontally.

The center of the beam pipe is made of thin-walled beryllium, allowing the new particles to permeate unobstructed, because of its low atomic number. It has a double structure for cooling, with the cooling medium flowing between the walls. On both sides of the pipe, Tantalum that has a high atomic number is used to shield against particles (noise) incoming from other parts of the SuperKEKB to prevent them from entering the detector. Electrons and positrons intersect at a low angle and to allow them to cross the interaction region at that vector, the pipe splits in two on both ends.

Mercury Target

Mercury Target

The Mercury Target Container Unit 8 was delivered to J - PARC (High Intensity Proton Accelerator Facility) on the 22nd of September 2017. Metal Technology Co. Ltd.’s engineering division was responsible for designing and manufacturing the Mercury Target for the 7th time. Under the guidance of the Japan Atomic Energy Agency (JAEA), we thoroughly reviewed the contents of the design and production of Unit 7,the previous product, and applied several improvements to this new Unit. As a result, we were able to complete it after a 2 year design and production period.In mid-April 2018, at J-PARK, a proton beam of around 300kW has been continuously irradiated under user manual operation. From the end of April, we have been able to meet our original goal of operating at 500kW.

An example of a nuclear fusion experiment device

Product name: Millimeter wave wide-band polarizer for ECH (electron cyclotron resonance heating)

Product details

Product details

Metal Technology Co. Ltd. has conducted collaborative research with members of the Quantum Science and Technology Research and Development Organization (QST), and Ibaraki University (Saegusa Laboratory) on the ECH (electron cyclotron resonance heating) of the superconducting tokamak plasma nuclear fusion experiment device “JT-60SA”. We have developed a high power wide-band polarizer compatible at millimeter wave of megawatts level. The wide-band polarizer for millimeter waves successfully developed this time can transmit, with high efficiency, high power millimeter waves (frequency: 110 GHz, 138 GHz) for heating plasma.

The polarizer, through its metal mirror which is equipped with a rotatable reflective diffraction grating, can produce arbitrary polarized waves which can enter the plasma. Through continued collaborative research the heat loss was reduced to 50% or less, the size was reduced by about 4 kg, and the cooling efficiency was improved in comparison to the prototype type.
