Stainless steel
in nuclear research

APPLICATION EXAMPLE

CERN
CH-1211 Geneva 23 www.cern.ch
Nuclear research

CERN, the European Organization for Nuclear Research, operates one of the largest scientific research
laboratories in the world. Its main field of activity is fundamental physics, in which the building blocks and the
laws of the universe are explored. CERN uses highly complex scientific instruments to study the basic
constituents of matter, the so-called fundamental particles. By examining what happens when these particles
collide, physicists are learning more about the basic laws of nature.

APPLICATION
SERTO products: Stainless steel unions
Application: Process lines

PARAMETERS
Medium: Demineralised water
Pressure: 15 bar
Temperature: 20 – 55° C

The circular accelerator and the insulators

The electromagnets used in the particle accelerator must generate a gigantic magnetic field. To achieve this,
the coils are under extremely high voltage, which causes very rapid heating of the conductor. This has to be
cooled with demineralised water. The outer walls of the water hoses are electrically insulated with the help of
insulators.

"We have used SERTO unions for the cooling circuit connections of our magnets because this
system allows radial mounting. The magnet coils are embedded in blocks and there is no room for
manoeuvring. There is no way we can move our lines axially. The SERTO principle enables us to
replace all our tube lines quickly."
