In experimental and applied particle physics, nuclear physics, and nuclear engineering, a particle detector, also known as a radiation detector, is a device used to detect, track, and/or identify ionizing particles, such as those produced by nuclear decay, cosmic radiation, or reactions in a particle accelerator. Detectors can measure the ...
Particle identification is the process of using information left by a particle passing through a particle detector to identify the type of particle. Particle identification reduces backgrounds and improves measurement resolutions, and is essential to many analyses at particle detectors.
A hodoscope (from the Greek "hodos" for way or path, and "skopos" an observer) is an instrument used in particle detectors to detect passing charged particles and determine their trajectories. Hodoscopes are characterized by being made up of many segments; the combination of which segments record a detection is then used to infer where the ...
Particle velocity can be calculated using the Doppler frequency from any signal, while the phase difference between two detectors determines particle size. [ 3 ] Fraunhofer diffraction : When a particle is at least 10 times larger than the laser wavelength and the scattering angle is 30° or smaller, the light intensity distribution pattern can ...
Detectors are designed to have one or two scintillation materials, depending on the application. "Single phosphor" detectors are used for either alpha or beta, and "Dual phosphor" detectors are used to detect both. [8] A scintillator such as zinc sulphide is used for alpha particle detection, whilst plastic scintillators are used for beta ...
Particle counters are used to support clean manufacturing practices in a variety of industrial applications. Clean manufacturing is required for the production of many electronic components and assemblies, pharmaceutical drug products and medical devices, and industrial technologies such as oil and gas.
Plot of variation of ion pair current against applied voltage for a wire cylinder gaseous radiation detector. Gaseous ionization detectors are radiation detection instruments used in particle physics to detect the presence of ionizing particles, and in radiation protection applications to measure ionizing radiation.
In physics, particle detectors are used in the experimental study of radioactivity, nuclear physics and particle physics; they are also important as a surveillance tool in nuclear safety. Particle detectors may range from the simplest, such as photographic film and Geiger counters , to the most complex used in particle colliders .
