CERN, the European Organization for Nuclear Research, has ordered 35 new “XDS” scroll pumps by Edwards, a leading manufacturer of sophisticated vacuum products and abatement systems and a leading provider of related value-added services. Edwards will supply 30 “XDS35i” and 5 “XDS10” dry scroll pumps. Some of these pumps are to replace an existing installation of previous generation Edwards’ scroll pumps; this upgrade to the newer generation of scroll pumps will take place during CERN’s scheduled extended shutdown (2013–2014). CERN’s Linear Accelerator 4 (Linac 4) test bench already has the new XDS pumps installed. The construction of the 80 m long accelerator is almost complete, and beams will begin to be produced in 2014. The full connection to the LHC injector chain is expected in 2017.
Edwards’ “XDS” range incorporates a unique dry pumping scroll mechanism that provides a robust and clean pumping solution. The pumps offer a completely oil free vacuum and are hermetically sealed; bearing life is significantly extended, therefore reducing maintenance and environmental impact. Annual interventions (repairs, labour and maintenance) for the scroll pumps are on average three times less than that for oil-sealed pumps. The high reliability of the XDS pumps and the long experience with them was another advantage for CERN.
