지난 1월 3일 한국에서 시험볼때, 새로운 Retell lecture 문제가 나왔었는데,
관련 자료를 찾아서 공유드립니다. 한번 읽어보시면 시험때 당황하지 않으실 꺼에요!!

Large Hadron Collider (that big blue tube) is a particle physics scientist in order to explore new particles, and micro-quantification of particles 'new physics' mechanism equipment, is a proton accelerated collisions of high-energy physics equipment, the English name For LHC (Large Hadron Collider).
The European Large Hadron Collider is the largest and most energetic particle accelerator in the world today. The Large Hadron Collider is located in a tunnel that is 100 meters deep beneath a 17-mile (including circular tunnel), Switzerland, French border near Jurassic. On September 10, 2008, the collision detector was first tested.
In 2010, scientists involved in the Large Hadron Collider (LHC) project said they may have "approached" the Higgs boson. The Higgs Boson, also known as the "God Particle," is said to play an important role in shaping the universe after the Big Bang. April 5, 2015 After a shutdown and maintenance of about two years, the European Large Hadron Collider was restarted and the second phase of its operation was officially launched with the hope of exploring the discovery of the existence of supersymmetric particles of the Higgs-coupled particles .
Here's a summary of knowledge according to candidates memories points :
Physicists at CERN in Geneva have achieved the first 7 TeV proton-proton collisions at the Large Hadron Collider. The LHC consists of a 27-kilometer ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way. The electromagnets are built from coils of special electric cable that operates in a superconducting state, efficiently conducting electricity without resistance or loss of energy. Here requires chilling the magnets to -271.3 ° C - a temperature colder than outer space. The collider has four crossing points, around which are seven sensors, each designed for certain kinds of research. The LHC to collides proton beams, but it can also use beams of heavy ions.
