NOVOSIBIRSK, November 16. /TASS/. Specialists of the Institute of Nuclear Physics of the Siberian Department of the Russian Academy of Sciences (RAS) will develop and manufacture, using vacuum welding, unique equipment for the FAIR research accelerator facility, which is under construction in Germany, head of the institute’s research laboratory Alexander Krasnov told TASS on Monday. FAIR is compared in scale with the Large Hadron Collider (LHC).

"Our task within the framework of the FAIR project is to install the tubes through which particle beams will move. There must be absolute vacuum there - the amount of residual gas molecules must be 100,000 billion times less than in the surrounding air." He said that these channels would be used for transporting particles from the place where they will be "born" to the accelerator rings where experiments will be conducted with them. According to him, the required level of airtightness can only be achieved by means of electron beam welding.

The electron beam welding technology itself is not new and is used, in particular, in the aerospace industry, he said. However, only the Institute of Nuclear Physics makes the beam tubes.
