Large Hadron Collider (LHC) Turkish Teachers’ Programme 3 The Large Hadron Collider (LHC) is the world’s largest and most powerful particle collider, and the largest single machine in the world, built by the European Organization for Nuclear Research (CERN) from 1998 to 2008. Its aim is to allow physicists to test the predictions of different theories of particle physics and high-energy physics like theStandard Model, and particularly prove or disprove the existence of the theorized Higgs boson and of the large family of new particles predicted by supersymmetric theories. The discovery of a particle matching the Higgs boson was confirmed by data from the LHC in 2013. The LHC is expected to address some of the unsolved questions of physics, advancing human understanding of physical laws. It contains seven detectors, each designed for certain kinds of research. The LHC was built in collaboration with over 10,000 scientists and engineers from over 100 countries, as well as hundreds of universities and laboratories. When protons arrive in the LHC they are travelling at 0.999997828 times the speed of light. Each proton goes around the 27km ring over 11 000 times a second. It is also the longest machine ever built. The Large Hadron Collider at CERN could be the most ambitious scientific undertaking ever. The results of LHC experiments will probably change our fundamental knowledge of the universe. Turkey became an associate member of CERN in 2014. As a result of this, the Turkish teachers’ programme which offers a one week training and orientation was started to take place twice a year in Geneva, Switzerland at the campus of CERN. BELS physics teacher Zeynep Tuğba Kahyaoğlu attented this training programme in the semester break with 48 Turkish teachers from different provinces of Turkey. They were given a certificate of completion after having 25 hours of lessons about particle physics, detector physics, astro particle physics, neutrinos, accelerators, Higgs, triggering and data collection. Moreover, they conducted the Cloud Chamber experiment which was actually mentioned in the IGCSE physics course. THE CLAPPER 2014 - 2015 46
