Major order from CERN for Oerlikon Leybold Vacuum

Delivery of over 50 leak detection systems for elementary particle and antimatter research in the CERN Large Hadron Collider

Pfäffikon, 11 February, 2013 – CERN, the renowned science centre for particle physics has placed an order with Oerlikon Leybold Vacuum for the delivery of over 50 mobile leak detection systems including the matching Remote Control System. With this order, Oerlikon has prevailed against a prestigious international competition. For Dr. Martin Füllenbach, CEO Oerlikon Leybold Vacuum, this success is a beacon for the future: "This is one of the largest orders for leak detection systems of one single customer in the applications within the branch of R&D. We are pleased that CERN continues to regard us as an important partner in their pioneering research."

Researchers at CERN in Geneva are examining what holds the world together - the discovery of the so-called Higgs particle recently revealed another fundamental insight. The world's largest accelerator LHC (Large Hadron Collider) is the heart of the major research institution. For the applications of the CERN Laboratory, the technical requirements on vacuum systems, such as quality, reliability and stability are very high. For decades, Oerlikon Leybold Vacuum has been a technology partner of the Geneva Laboratory and has delivered several vacuum systems and components.

For the experiments at the LHC, it is imperative to maintain a pure ultrahigh vacuum continuously in the 27 km long underground pipeline. Accordingly, the helium leak detection at CERN is of primary importance. If the scarce and expensive noble gas escapes from the storage ring, no more experiments can be performed, as the temperature in the system needs to be kept constant using helium at -271.3 °C. Only under these conditions the particles will travel at the speed of light and finally collide.

The Oerlikon Leybold Vacuum solution is characterized by a quick start, extremely short reaction times in leak detection, high flexibility and reliability as well as innovative features such as wireless USB port as well as touch panels with graphic user interfaces. Another plus: Oerlikon Leybold Vacuum offers training programs for the full range of leak detection applications – also on site. The head of CERN's Vacuum, Surface and Coatings Group, Dr. José Miguel Jimenez says: "Oerlikon Leybold Vacuum is one of the few technology suppliers who meet the extreme requirements of CERN high energy particle accelerators in terms of vacuum and leak detection systems. We can rely on solutions from Oerlikon Leybold Vacuum."

Oerlikon CEO Michael Buscher says: "The success on this tender demonstrates once again that the technologically advanced solutions we offer are essential for research applications. We are proud to support CERN in answering the basic questions of physics also in the future."
