What detectors are used in the LHC?

Detectors. Eight detectors have been constructed at the LHC, located underground in large caverns excavated at the LHC’s intersection points. Two of them, the ATLAS experiment and the Compact Muon Solenoid (CMS), are large general-purpose particle detectors.

How does LHC Atlas work?

ATLAS is one of two general-purpose detectors at the Large Hadron Collider (LHC). Beams of particles from the LHC collide at the centre of the ATLAS detector making collision debris in the form of new particles, which fly out from the collision point in all directions.

How does a muon detector work?

Typical muon detectors consist of photomultiplying tubes lined with a scintillator, a material that emits light when struck by a charged particle. When a particle such as a muon bounces through the detector, the photomultiplying tube multiplies the current produced by the emitted light.

What is Atlas and CMS?

ATLAS and CMS are the two ‘general-purpose’ detectors at the LHC. They’re looking for any new particles or unknown physics which the LHC’s record-breakingly high energies might allow us to observe for the first time.

What is the difference between CMS and Atlas?

The ATLAS detector is about 25 m high, 45 m long and weighs about 7000 tons. The CMS detector is a bit smaller, but it is much heavier (about 12 000 tons). Overall, these detectors take the role of high-speed three-dimensional digital cameras.

Where are muons found?

upper atmosphere
Muons are generated in the Earth’s upper atmosphere by cosmic rays (high energy protons) colliding with atomic nuclei of molecules in the air. Muons can also be produced in a two-step process at large research facilities.

What does detector mean?

Definition of detector : one that detects: such as. a : a device for detecting the presence of electromagnetic waves or of radioactivity. b : a rectifier of high-frequency current used especially for extracting the intelligence from a radio signal.

What is the application of silicon detectors in particle physics?

Silicon detectors are widely used in experiments in particle physics. The application of this detector technology is mostly for tracking detectors, i.e. detectors which measure the position of charged particles. From this information, track reconstruction software from the experiments deduces many parameters.

What are silicon vertex detectors used for?

Silicon vertex detectors employed in all LEP experiments at CERN and in the SLD experiment at SLAC opened a new physics window through the reconstruction of b-quark decays. The fact that silicon detectors have a high inherent radiation resistance enabled the use of them in the harsh environment of hadron colliders.

What are abstract gas \\flled detectors?

Sumanya Sekhar Sahoo School of Physical Sciences National Institute of Science Education and Research Bhubaneswar Abstract Gas \\flled detectors are one of the oldest and most widely used radiation detectors and based on the e\ects produced when a charged particle passes through a gas.

What is the achievable position resolution of a strip detector?

The achievable position resolution depends, as in the case of strip detectors, on the pixel dimensions and on the electronics. If the signal height is measured and used to interpolate between the pixels a position resolution of a few micrometers is achievable.
