How are particles detected in LHC?
Accelerators at CERN boost particles to high energies before they are made to collide inside detectors. Tracking devices reveal the path of a particle; calorimeters stop, absorb and measure a particle’s energy; and particle-identification detectors use a range of techniques to pin down a particle’s identity.
How fast do the particles in the LHC at CERN go?
speed of light
The LHC accelerates beams of particles, usually protons, around and around a 17-mile ring until they reach 99.9999991 percent the speed of light.
How is the data from the LHC processed?
What data to record? Collisions in the LHC generate particles that often decay in complex ways into even more particles. Electronic circuits record the passage of each particle through a detector as a series of electronic signals, and send the data to the CERN Data Centre for digital reconstruction.
How are particles detected?
Physicists investigate particle interactions by placing devices known as particle detectors in a region where collisions are expected. Particles that emerge from the collision leave evidence of their passage through the detectors.
What is CERN data?
The CERN Data Centre is the heart of CERN’s entire scientific, administrative, and computing infrastructure. All services, including email, scientific data management and videoconferencing use equipment based here. The 230 000 processor cores and 15 000 servers run 24/7.
What information can we find from Analysing the resulting particles of collisions?
By analyzing the trajectories and energies of the particle, we can calculate the dynamics of the collision and search for new particles. After repeating thousands of collisions, a statistically significant result can be obtained about the existence of a new particle.
What is detection techniques?
The purpose of most pattern detection methods is to represent the variation in a data set in a more manageable form by recognising classes or groups. The data typically consist of a set of objects described by a number of characters.
