Unlike most metals, beryllium has a low mass absorption coefficient, which means that the transmission of x-rays is higher. This makes beryllium ideal for use as an x-ray detector entrance window.
Bremstrahlung
Braking radiation produced by the electrons being decelerated in the target of the x-ray tube. These rays with energies from 0 to the maximal corresponding to the accelerating voltage form the continuous part of the x-ray emission from the x-ray tube.
CCD Camera
CCD (Charge Coupled Devices) Image Sensors are used in digital cameras, scanners, and other optical devices. CCDs are widely used in scientific applications where high-quality image data is required.
Chelates
Chemistry. To combine (a metal ion) with a chemical compound to form a ring.
EDXRF
Energy Dispersive X-ray Fluorescence.
EDXRS
Energy Dispersive X-ray Spectroscopy.
EDXS
Energy Dispersive X-ray Spectroscopy.
FET
The Field-Effect Transistor (FET) relies on an electric field to control the shape and hence the conductivity of a channel of one type of charge carrier in a semiconductor material.
FWHM
Full-Width at Half-Maximum. It is a feature be used to assess the resolution of a spectral peak. In EDXRF FWHM is defined as energy resolution measured for Mn-Ka characteristic emission.
International Union of Pure and Applied Chemistry.
Peltier element
A Peltier element is not a heating element or a cooling element, it is a heat pump. It transfers heat energy from one side to the other; the direction of transfer is decided by the polarity of the electrical current that powers it.
