Pfeiffer Vacuum supplies vacuum solutions for the world\'s largest and most powerful particle accelerator

• Long-standing partnership between CERN and Pfeiffer Vacuum
• Vacuum technology for probing the fundamental structure of the universe
• HiPace turbopumps for the Large Hadron Collider

Asslar, March 5, 2018. Pfeiffer Vacuum has received yet another major order for turbopumps and turbo pumping stations from CERN. CERN is situated in Geneva on the Franco-Swiss border and is the largest center for particle physics research in the world. Its main business is fundamental physics – finding out what the universe is made of and researching the basic constituents of matter. The particle accelerator LHC (Large Hadron Collider) has a circumference of some 27 kilometers and is used for colliding proton and ion beams at nearly the speed of light. The accelerated particles travel in beam lines, which require ultra-high vacuum (UHV) conditions. These beam lines are pre-evacuated with turbo pumping stations. Furthermore, turbopumps with a very high compression ratio for light gases are then responsible for generating the insulation vacuum. The insulation vacuum is necessary for the operation of the superconducting magnets at a temperature of -271 °C. Andreas Schopphoff, Head of R&D Market Segment: “The cooperation between CERN and Pfeiffer Vacuum is based on many years of working together in a spirit of trust. We are very proud that CERN has chosen Pfeiffer Vacuum products again for its future projects. Since the pumps’ application is one that has never been realized before, the technical requirements for this project are especially high.

The new order is for HiPace turbopumps and HiCube turbo pumping stations that meet those high demands.” Arthur Pfeiffer GmbH developed the turbopump in 1958 with the objective of generating a hydrocarbon-free vacuum. Today, turbopumps from Pfeiffer Vacuum are considered the epitome of cutting-edge technology, dependability and ultra-high performance. At the time, CERN was one of the first customers to buy this innovative technology and has continued to be a major user of Pfeiffer Vacuum products to this day. Generating the vacuum inside the LHC, measuring it and analyzing the partial pressure requires comprehensive vacuum technology, a major part of which is being supplied by Pfeiffer Vacuum. CERN was founded in 1954 and now employs around 2,500 staff and hosts more than 10,000 visiting scientists from all over the world.
