Electrical Heat Tracing for the Generation of High Purity Vacuum in Test Facilities
Modern electrical heat tracing technology plays a decisive role in many fields, e.g. for the generation of high purity vacuum. For this application handmade heating jackets and mats are produced by eltherm which are custom-fit and correspond to the requirements of the customers. This is essential for the generation of optimal vacuum conditions! One application of heating jackets and mats is to heat vacuum pumps, piping systems and vacuum chambers in order to guarantee optimal conditions for high purity vacuum within a particle accelerator ring. For this application products are produced which heat the vacuum systems up to 300°C to generate high purity vacuum.
Use of Heating Jackets and Mats at CERN:
At CERN (Conseil Européen pour la Recherche Nucléaire – European Organization for Nuclear Research) eltherm heating jackets and mats are used for the so-called Large Hadron Collider (LHC). For this application eltherm delivered approx. 3500 heating jackets and mats to CERN.
Heat for the Nuclear Explosion
CERN is an international organization whose purpose is to operate the world‘s largest particle physics laboratory, which is situated near Geneva in Switzerland. CERN‘s main function is to provide the particle accelerators and other infrastructure needed for high-energy physics research. The biggest particle accelerator in the world started running near Geneva in 2007. 9500 scientists and employees of the European Research Center CERN will let proton rays clash together in the particle accelerator ring which is 27 km long and costs 1.9 Mrd. Euro. This experiment can only work if the elementary particles circulate in a vacuum. For this reason, the eltherm GmbH delivers heating jackets and mats for the so-called Large Hadron Collider (LHC). The jackets and mats will work in a temperature range of 300° C and are used to heat pumps, piping systems and chambers in order to improve those vacuum conditions. This little detail in the major particle physics laboratory in the world is very important for the experimental physicists.
They indeed need the best and most precise tools. The international scientists want to research the composition of the matter with the mentioned LHC. The accelerator speeds up the protons to nearly speed of light and detectors make them visible. The LHC brings the proton rays to clash with the help of energy from 14 so-called TeV. TeV is an energy unit which is common within the particle physics. (A TeV is nearly the kinetic energy of a flying mosquito.) What makes the LHC so exceptionally? It is the concentration of this energy to a tiny volume which is by one million times smaller that the one of the mosquito.
But before the scientists can research the so-called super symmetric particles, the controversial “Higgs-Boson” as well as the “Quark-Gluon-Plasma”, the team from eltherm has to do its work. A part of employees of eltherm sews the self produced heating cables with the corresponding insulations into a backing fabric of the mats and jackets. These mats and jackets are custom-made to the shape of the respective objects just like a tailor-made suit, which can be taken off again at any time – for example for maintenance work.
