Metromecánica participera au MetalMadrid

A nouveau, Metromecánica participera comme exposant au salon MetalMadrid 2017, les 15 et 16 novembre à l’IFEMA – Feria de Madrid. Hall 2, stand A08.

MetalMadrid est l’unique salon du secteur industriel du centre de l’Espagne. Il réunira des professionnels de différents secteurs industriels: Automobile, Ferroviaire, Aéronautique, Espace, Biens d’équipement, Constructions métalliques, Usinage, Robotique, Automatisation, Ingénierie, Matériaux composites, etc.

C’est une excellente occasion de venir rencontrer tous les points d’intérêt de ces secteurs: Machinerie, Sous-traitance, Fournitures, Ingénierie, Matériaux et autres.

Le personnel technique de Metromecánica, en tant que société de référence dans les solutions de métrologie clés en main, sera présent pour vous parler de leurs expériences et vous conseiller pour vos problématiques de métrologie.

Si vous souhaitez une invitation, s’il vous plaît contactez-nous ici.

Men of measure in ITER

“Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed rounds.” [From the Greek historian Herodotus; also inscribed on the New York City Post Office.]

This phrase, which has been attributed to the men and women who brave all kinds of climatic conditions to deliver daily mail, could just as well be used to describe the diligence of the ITER metrology team members who have been out monitoring the Assembly Hall since August of last year.

Why are they outside in the heat of the summer and the cold of the pre-dawn winter hours? The Assembly Hall stands at over 60 metres in height and will move during windy days, expand during hot days and contract during cold days. Systems that are supported off the building structure will move with the building.

This is of particular concern for the electron cyclotron transmission line, which weaves its way from the Radio Frequency Building, through the Assembly Hall and on to the Tokamak Building. As the Assembly Hall “moves” it will distort the electron cyclotron transmission line at the junction between the buildings. These distortions will perturb the transmission of the microwave beams, which will increase the heating of the transmission line further downstream as well as the launching antenna system in the port plugs.

Because the microwave beams represent up to 1MW of power with peak power densities exceeding 1GW/m2, large distortions could generate large heat loads.

The role of the metrology team is to characterize the maximum displacements of the Assembly Hall and to validate the predicted movements of up to +/-15 mm on a typical day. This may sound small but—relative to the alignment requirements for the electron cyclotron transmission line (waveguide supports aligned with sub-millimeter precision over a distance of 4m)—it is enormous.

In addition, the metrology team has been measuring the relative position of the three buildings to provide an “as built” footprint, with the desired sub-millimeter precision, of the trajectory that the electron cyclotron transmission line will follow.

The measurements were taken at a critical point in construction during the autumn, when the ground floor for all three buildings was sufficiently established and the opening between the Assembly Hall and the Radio Frequency Building not yet closed in. This allowed the precise positioning of the Assembly Hall relative to the Radio Frequency Building.

The first round of measurements will be completed near the end of January with all information passed on to the electron cyclotron team, which will build an “as built” CATIA model for transmission line passage. In addition, the building displacements will be used to revise the requirements on the transmission line load specifications. Another round of measurements will be performed once the Tokamak, Assembly Hall and Radio Frequency buildings are completed in the 2019 period.

The electron cyclotron resonance heating system (ECRH) will heat the electrons in the plasma with a high-intensity beam of electromagnetic radiation at a frequency of 170 GHz, the resonant frequency of electrons along the vertical cylinder intersection near the plasma centre. The electrons, in turn, transfer the absorbed energy to the ions by collision. ECRH is one of three external heating systems that will help to bring the plasma to 150,000,000 °C.
