How do you use scintillating in a sentence?
Scintillating sentence example. Maybe some scintillating conversation would break the ice. Hmmm, must make for scintillating pillow talk. The gas chandeliers were usually of glass, with drops on the loops scintillating in the light like diamonds.
What causes scintillation?
Scintillation is caused by small-scale (tens of meters to tens of km) structure in the ionospheric electron density along the signal path and is the result of interference of refracted and/or diffracted (scattered) waves.
How does a scintillator work?
In scintillation detectors the material of the detector is excited to luminescence (emission of visible or near-visible light photons) by the absorbed photons or particles. The number of photons produced is proportional to the energy of the absorbed primary photon. The light pulses are collected by a photo- cathode.
What is scintillation Class 12?
Scintillation Counter is an instrument that is used for measuring ionizing radiation. “It comprises the scintillator that generates photons in response to incident radiation”, a PMT tube is used to convert an electronics and electric signal to process the signal.
What is scintillator crystal?
A scintillation crystal absorbs gamma photons by one or more collision processes and converts some of their energy into visible light and ultraviolet (UV) photons.
How do you use sanctimonious in a sentence?
We want to be a little less sanctimonious about this. We also ought to avoid being too sanctimonious. I do not blame the miners for not wanting a lecture from him, or not wishing to have a sanctimonious letter from him. Many of us drive motor cars, so we cannot afford to be sanctimonious about this.
Can scintillating be used as a verb?
Scintillating can be an adjective or a verb.
What are the scintillation effects?
Scintillation of radio waves impacts the power and phase of the radio signal. Scintillation is caused by small-scale (tens of meters to tens of km) structure in the ionospheric electron density along the signal path and is the result of interference of refracted and/or diffracted (scattered) waves.
What are Scintillations give the construction and working of scintillation counter?
It consists of a scintillator which generates photons in response to incident radiation, a sensitive photodetector (usually a photomultiplier tube (PMT), a charge-coupled device (CCD) camera, or a photodiode), which converts the light to an electrical signal and electronics to process this signal.
What is the definition of scintillation counter in chemistry?
What is a scintillator material?
What Are Scintillation Materials? Scintillators are materials that absorb energetic radiation such as gamma rays, X-rays, or neutrons and convert that energy into short bursts of visible photons. These photons are then converted into electrical pulses by photo-detectors.
What is sanctimonious person?
