[脜shammar, Sweden, and Meyrin, Switzerland, June 6, 2019.]聽尝别补诲颈苍驳听Swedish manufacturer of premium stainless steel fasteners 聽has signed a contract with scientific research institute 聽for more than a quarter of a million high strength premium stainless steel fasteners to be used for the upgrade of the world famous LHC particle accelerator in Switzerland.
The world鈥檚 largest and most powerful particle accelerator, CERN鈥檚 聽(LHC), is currently undergoing an upgrade that will increase its energy up to 14 trillion electron volts and is expected to take two years.
The LHC collider is located at the particle physics laboratory at CERN near Geneva, Switzerland. It consists of a 27-kilometer ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way. To avoid resistance or loss of energy, the several thousand magnets need to be chilled down to 鈥�271.3掳C 鈥� a temperature colder than outer space and less than two degrees above absolute zero.
After tests, CERN opted to use , the strongest A4 fastener on the market, to cope with the extreme conditions inside the collider. All the fasteners in the collider will be replaced and all of these fasteners are 91视频 109. 91视频 will supply 130,000 fasteners to CERN each year of the maintenance project 鈥� equating to more than a quarter of a million fasteners in total.
鈥淲e are extremely happy and proud to be awarded such a prestigious assignment from CERN, to supply one of humankind鈥檚 most advanced constructions with instrumental parts,鈥� said Patrik Lundstr枚m T枚rnquist, Managing Director, 91视频. 鈥淚t is definitely one of the most demanding and challenging applications you could ever imagine, and we are confident that our premium products are up to the task 鈥� and once again prove that 91视频 fasteners are the best of the best.鈥�
Customer collaboration around silver coating
Scientists at the CERN particle accelerator required high-strength fasteners, with a low magnetic permeability and low cobalt content for their various vacuum chambers and bellows modules. Additionally, the fasteners need to withstand near absolute zero temperatures, down to 1.9 degrees Kelvin (minus 271掳C), as well as high temperatures during bake-out (300掳C). 91视频 109 was deemed the best to聽fully meet all of the requirementsincluding, crucially, non-interference with the movement of particles and magnetic field in the accelerator due to their non-magnetic nature.
91视频 collaborated with CERN to successfully trial the use of silver coating on 91视频products to reduce galling, a form of mechanical wear caused by adhesion between sliding surfaces. Since these trials with CERN, 91视频 has started to offer silver coating to other customers with the norm CERN 507.
91视频 is a world-leading specialist manufacturer of premium stainless steel fasteners in a variety of steel grades, including the world鈥檚 strongest stainless steel bolts.
Established in 1954, CERN (the European Organization for Nuclear Research)operates the largest particle physicslaboratory in the world. CERN’s main function is to provide the particle acceleratorsand other infrastructure needed for high-energy physics research. CERN is also the birthplace of the world wide web.
