How Do You Detect Cosmic Muons

How do you find cosmic muons?

Further restrictions must be put in place in order to detect muons with specificity. Typically, plastic scintillator detectors are used for this. When a charged particle travels through the material, the detector emits a photon. Nuclear emulsion, scintillation, and gaseous muon detectors are the three types that have been employed.Scientists use muons for archeological purposes to look inside big, dense objects like the pyramids in Egypt. Muons can help detect dangerous nuclear material and see into damaged nuclear power plants.In order to reconstruct the shape of dense materials in between, shielded or not, detectors above and below a sample can measure the particle’s flight paths and penetrate thick steel and lead.When cosmic rays strike molecules in the upper atmosphere, muons are the byproduct. Muons travel to earth with an average speed of 0 point 994c. On the surface of the earth, one muon (or 10,000 muons per square meter) travels through a 1 cm2 area once every minute.According to the Standard Model of particle physics, the muon is one of the fundamental subatomic particles and one of the universe’s most fundamental building blocks. Despite being more than 207 times heavier than electrons, muons are similar to them. An adult and a small elephant are roughly equivalent in size.

Why are muons so difficult to find?

None of the CMS calorimeters can stop muons because, unlike most particles, they can pass through several meters of material with little energy loss. The only particles that are likely to produce a distinct signal are muons, so chambers to detect them are placed in the experiment’s outermost region. The negatively charged muon and its positively charged antiparticle are its two different states.We can produce muons by taking a narrow, high-intensity beam of protons and running it into a target made of a metal, such as titanium. This produces a beam of another fundamental particle called the pion. Pions form a beam which fans out.The muon is one of 16 fundamental particles that make up everything—all matter, all forces, all energy—in the visible universe. These particles exist in their own microscopic community.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.Muons have either a positive or negative unit electric charge (expressed as µ+ or µ-) and a low mass—approximately one-ninth that of a proton. They have a mean lifetime of approximately 2.

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. A muonic atom is an atom in which a negatively charged muon is captured by a nucleus. To form such an atom, a target material is bombarded with a negative muon beam. The muons suffer successive kinetic energy losses by their interaction with the outer atomic electrons in the target.Muons are elementary particles which have no substructure. That means; these particles are very small, and there are no quark or antiquark particles in them. These particles are similar to electrons. They have -1 electrical charge and the spin is ½.Apart from the loss by ionisation, muons can lose energy by radiative emission (brems- strahlung), electron positron pair production, direct muon pairs production and by nuclear interactions.Like the electron, the muon has a magnetic field that makes it act like a tiny bar magnet. As muons travel, they generate various particles that briefly pop in and out of existence. These ephemeral particles slightly increase the muon’s magnetism, known as its magnetic moment.They can replace electrons in atoms. If you point this beam of muons into a target, then some of the muons will replace electrons in the target’s atoms. This is very nice because these “muonic atoms” are described by non-relativistic quantum mechanics with the electron mass replaced with ~100 MeV.

How are muons measured?

The name of the Muon g − 2 collaboration stems from the fact that the experiment measures the muon anomaly aμ=(g−2)/2, where g is a dimensionless magnetic moment that relates a particle’s spin S to its magnetic moment μ, charge q, and mass m: μ=g(q/2m)S. In a strong magnetic field, the direction of the muon’s magnet precesses, or wobbles, much like the axis of a spinning top or gyroscope. The strength of the internal magnet determines the rate that the muon precesses in an external magnetic field and is described by a number that physicists call the g-factor.

Why is it called muon?

The name is pronounced “myoo-on,” and comes from the Greek letter μ, which we spell “mu” and pronounce “myoo. A muon is a type of particle very much like an electron. In fact, it is exactly the same as an electron – except heavier. The letter µ in chemistry In chemistry, µ refers to the elementary particles muon and antimuon. A muon is similar to an electron. However, its mass is about 207 times the mass of the electron.

Do muons affect humans?

About 10,000 muons pass through our bodies every minute. Some of these muons will ionize molecules as they go through our flesh, occasionally leading to genetic mutations that may be harmful. In conclusion, patterns of DNA mutations observed as patterns of human disease closely adhere to patterns expected under conditions of a constant air shower of muons causing constant DNA damage. Thus, DNA damage by muons explains evolution, aging, and disease (Colchero et al. Yamamoto et al.The muon was discovered as a constituent of cosmic-ray particle “showers” in 1936 by the American physicists Carl D. Anderson and Seth Neddermeyer.
