This small reflective tag shows the magnetic field lines in a side and the CERN logo in the other, it can be attached to your clothes or bags to make you clearly visible and safer on the streets in winter or at night.
The Large Hadron Collider (LHC) contains 1232 dipole magnets, which bend the paths of the protons moving at 99.999991% of the speed of light along the 27 km LHC ring.
Each magnet weighs 35 tonnes and is 15 metres long, with a current of 11,000 amperes flowing through its coils, which are cooled to -271°C.
The CERN logo is made up of two components :
The word "CERN", which is the acronym derived from the Organization's first official title : Conseil Européen pour la Recherche Nucléaire, or European Council for Nuclear Research. Today, our understanding of matter goes much deeper than the nucleus, and CERN's main area of research is particle physics. Because of this, the laboratory operated by CERN is often referred to as the European Laboratory for Particle Physics.
The interlaced rings, which are a simplified representation of the accelerator chain. The CERN’s current logo dates from 1968, when a decision was made to change the original one. Some 114 new designs were submited, many of which used CERN’s experiments as inspiration. The final design used the original lettering, surrounded by a schematic of a synchrotron, beam lines and particle tracks. Today’s logo is a simplified version of this.
