im the student of electronic and telecommunication engineering . i have ambition and goals to do
performance after completing engineering . now i want the seminar topic of large hydron collider so please provide me that argently.i am now giving the seminar on this subject but i dont have the material or report and also i do not have the slides also . tommorow is my last date of registration of my seminar topoc on large hydron collider . i always trying your website but alwas failed to download seminar. please provide me now.

large hadron collider seminar reports pdf file
The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator. It first started up on 10 September 2008, and remains the latest addition to CERN’s accelerator complex. The LHC consists of a 27-kilometre ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way.
Inside the accelerator, two high-energy particle beams travel at close to the speed of light before they are made to collide. The beams travel in opposite directions in separate beam pipes – two tubes kept at ultrahigh vacuum. They are guided around the accelerator ring by a strong magnetic field maintained by superconducting electromagnets. 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. This requires chilling the magnets to ‑271.3°C – a temperature colder than outer space. For this reason, much of the accelerator is connected to a distribution system of liquid helium, which cools the magnets, as well as to other supply services.
Thousands of magnets of different varieties and sizes are used to direct the beams around the accelerator. These include 1232 dipole magnets 15 metres in length which bend the beams, and 392 quadrupole magnets, each 5–7 metres long, which focus the beams. Just prior to collision, another type of magnet is used to "squeeze" the particles closer together to increase the chances of collisions. The particles are so tiny that the task of making them collide is akin to firing two needles 10 kilometres apart with such precision that they meet halfway.
All the controls for the accelerator, its services and technical infrastructure are housed under one roof at the CERN Control Centre. From here, the beams inside the LHC are made to collide at four locations around the accelerator ring, corresponding to the positions of four particle detectors – ATLAS, CMS, ALICE and LHCb.
How the large hadron collider works
One hundred meters (or about 328 feet) underground, beneath the border between France and Switzerland, there's a circular machine that might reveal to us the secrets of the universe. Or, according to some people, it could destroy all life on Earth instead. One way or another, it's the world's largest machine and it will examine the universe's tiniest particles. It's the Large Hadron Collider (LHC).
The LHC is part of a project helmed by the European Organization for Nuclear Research, also known as CERN. The LHC joins CERN's accelerator complex outside of Geneva, Switzerland. Once it's switched on, the LHC will hurl beams of protons and ions at a velocity approaching the speed of light. The LHC will cause the beams to collide with each other, and then record the resulting events caused by the collision. Scientists hope that these events will tell us more about how the universe began and what it's made of.
The LHC is the most ambitious and powerful particle accelerator built to date. Thousands of scientists from hundreds of countries are working together -- and competing with one another -- to make new discoveries. Six sites along the LHC's circumference gather data for different experiments. Some of these experiments overlap, and scientists will be trying to be the first to uncover important new information.
The purpose of the Large Hadron Collider is to increase our knowledge about the universe. While the discoveries scientists will make could lead to practical applications down the road, that's not the reason hundreds of scientists and engineers built the LHC. It's a machine built to further our understanding. Considering the LHC costs billions of dollars and requires the cooperation of numerous countries, the absence of a practical application may be surprising.
