semiconductor detector

Semiconductor detectors for high-energy particles are used in large numbers.

In semiconductor detectors, an electric field is applied to the detector volume.

When they contain many diodes with different functions, the more general term semiconductor detector is used.

A third energy dispersive method for counting alpha particles is to use a semiconductor detector.

The X-rays are detected using a semiconductor detector, which is an array of silicon diodes.

In an energy-dispersive X-ray spectrometer semiconductor detector measures energy of incoming photons.

Since optical systems are equipped with semiconductor detectors and comprehensive electronics, it is most important to pay attention to safe electro-magnetic screening.

This would be by means of either a scintillation detector or a semiconductor detector, placed in close proximity to the body.

Consequently, in semiconductor detectors the statistical variation of the pulse height is smaller and the energy resolution is higher.

Semiconductor detectors have found broad application during recent decades, in particular for gamma and X-ray spectrometry and as particle detectors.

He helped develop the theory of charge collection in semiconductor detectors and the formation of current or voltage pulses at the input of associated electronics.

For information about semiconductor detectors in radio, see Diode, rectifier, detector (radio) and cat's-whisker detector.

In contrast, EDS uses a solid state semiconductor detector to accumulate X-rays of all wavelengths produced from the sample.

Semiconductor detectors can be made in radial segments that can be switched in or out to control the type of contrast produced and its directionality.

The point-contact semiconductor detector was subsequently resurrected around World War II because of the military requirement for microwave radar detectors.

A semiconductor detector is a device that uses a semiconductor (usually silicon or germanium) to detect traversing charged particles or the absorption of photons.

The resulting pattern of the radiation is then ultimately detected by a detection medium including rare earth screens (which surround photographic film), semiconductor detectors, or X-ray image intensifiers.

With a metal oxide semiconductor detector, Ms. Peets said, carbon monoxide is detected through the periodic heating of a chemical in the unit to 300 degrees Celsius.

It has also been applied to materials used for particle detectors or semiconductor detectors used in nuclear research, for example, high-resistivity silicon, cadmium telluride (CdTe), etc.

The MI and HI instruments are all silicon semiconductor detector telescopes utilizing the well-known dE/dx x E algorithm for isotope identification: mass and nuclear charge.

Some common principles used to detect X-rays include the ionization of gas, the conversion to visible light in a scintillator and the production of electron-hole pairs in a semiconductor detector.

In this configuration, the semiconductor detector is placed opposite to the surface of the sample being analyzed, and an energy spectrum of charged particles emitted by the neutron-induced reaction is acquired.

The value of optically coupling a solid state light emitter to a semiconductor detector for the purpose of electrical isolation was recognized in 1963 by Akmenkalns,et al. (US patent 3,417,249).

When semiconductor detectors are used in harsh radiation environments, defects begin to appear in the semiconductor crystal lattice as atoms become displaced because of the interaction with the high-energy traversing particles.

All semiconductor detectors function rather inefficiently in crystal receivers, because the low voltage signal level is too low to result in much difference between forward better conduction and reverse weaker conduction.
