After two years, the Large Hadron Collider (LHC) at CERN near Geneva will start again. Accelerator reaches almost twice the energy of the collision than before.
Large Hadron Collider is the most complex machine constructed by man. This type of microscope that allows to explore the world in a very small scales. This leads him to the collision of two moving in opposite particle beams – the proton nuclei and lead. Since February 2013,., After three years of intensive work, the LHC had a break – the unit has been repaired and modernized so as to be able to achieve more than ever before the collision energy. This allows you to better investigate the nature of elementary particles.
Large Hadron Collider restarts March 23. The first particle collisions with power 13 TeV (teraelektronowoltów) will take place in late May and early June. In addition to the increased energy will be called twice. luminosity, ie the intensity of the collision (with 20 million times per second to 40 million times per second). The second round of data collection (ie. Run 2) will run from 2015. To 2017.
After a new start of the LHC will change the nature of work of physicists involved in the experiment. Now they will have, among others, participate in the so-called. szychtach, or changes in the work on the detector, to oversee the data collection process, ensuring the quality of his work. Besides, they conducted a preliminary analysis of the new data. In all these activities will also be involved Poles.
Officially, Poland became a member of the European Organization for Nuclear Research CERN in 1991. Today, with all projects and experiments at CERN, working almost 300 experts from Polish research units including approx. 100 in experiments at the LHC.
