how do muon detectors 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.

Muons arriving on the Earth's surface are created indirectly as decay products of collisions of cosmic rays with particles of the Earth's atmosphere.

A megger is a megohmeter, measures insulation resistance. A hipot tester basically works the same way, but measures leakage current. If you see a fault with the megger, you will see a fault with the hipot. The hipot stresses the insulation weak points at higher voltage levels than the megger will.

Muons are heavier, having more than 200 times as much mass as electrons. Taus, in turn, are approximately 3,700 times more massive than electrons. Each charged lepton has an associated neutral partner, or neutrino (i.e., electron-, muon-, and tau-neutrino), that has no electric charge and no significant mass.

The Large Hadron Collider has four main particle detectors: ALICE, ATLAS, CMS and LHCb. These detectors are showered with the particles produced when the two beams of protons circulating around the LHC collide. ... Particles entering a calorimeter are absorbed and a particle shower is created by cascades of interactions.

Muons are created when cosmic rays traveling through space strike molecules in the atmosphere, some 10 kilometers above Earth's surface. Even moving at nearly the speed of light, a muon should only be able to travel about 700 meters before it decays, so you might think no muons could ever reach Earth.

CZT detectors are fabricated with very thin metalized electrode geometries deposited on the detector surfaces. These electrodes are then electrically biased creating a difference in electrical potential within the detector volume.

The MCCB uses a temperature sensitive device (the thermal element) with a current sensitive electromagnetic device (the magnetic element) to provide the trip mechanism for protection and isolation purposes. This enables the MCCB to provide: ... Electrical Fault Protection against short circuit currents, and.

A Geiger counter, or a Geiger-Muller tube, is used for detecting and measuring alpha, beta and gamma radiation. It consists of a pair of electrodes with a high voltage running between them. ... Radiation entering the tube ionizes the gas. Electrons and ions are attracted to the electrodes, producing an electric current.

A Geiger counter is an instrument used for detecting and measuring ionizing radiation. Also known as a Geiger–Muller counter (or Geiger–Müller counter), it is widely used in applications such as radiation dosimetry, radiological protection, experimental physics, and the nuclear industry.

Abstract. The operation of a gas-filled detector is based on the ionization of gas molecules by radiation, followed by collection of the ion pairs as charge or current with the application of a voltage between two electrodes.

Geiger Counter, with Geiger-Mueller (GM) Tube or Probe—A GM tube is a gas-filled device that, when a high voltage is applied, creates an electrical pulse when radiation interacts with the wall or gas in the tube. These pulses are converted to a reading on the instrument meter.

Muons were formerly called "mu mesons", but are not classified as mesons by modern particle physicists (see § History), and that name is no longer used by the physics community. ... Because muons have a greater mass and energy than the decay energy of radioactivity, they are not produced by radioactive decay.

Perhaps the most common type of X-ray detector uses an electric current to measure incoming X-rays. In this type of detector, an X-ray interacts with a material freeing an electron. ... Below, we briefly describe some of the common types of X-ray detectors that use these cascades of electrons to detect incoming X-rays.

Muons are created when cosmic rays traveling through space strike molecules in the atmosphere, some 10 kilometers above Earth's surface. Even moving at nearly the speed of light, a muon should only be able to travel about 700 meters before it decays, so you might think no muons could ever reach Earth. Not so!

The coil or search head of these detectors consists of two separate coils of wire. The outer coil produces a VLF, below 30kHz, impulse which is directed into the ground. When the impulse comes into contact with a metal object below ground, the impulse is reflected back at a different frequency.
