A device for estimating the spectral peak of bremsstrahlung X-radiation of up to SIMILAR 1MEV from either a continuous or pulsed wave X-ray beam uses a differential absorption technique. The variation caused by the X-radiation in different substances, e.g. nitrogen, argon and krypton, is ...
此时对应的波长被称为临界波长(critical wavelength) \lambda_{\text{K}} [6]。由此,在 \left( \frac{\mu}{\rho} \right) - \lambda 图线上出现的特征线被称为吸收限(absorption edge),如下图所示。 X射线滤光片(X-ray filter) 媒质的吸收限位置对于对由靶材产生的X射线进行的选择有重要作用。在选择...
For specific (commensurable) wavelengths, the induced signal is zero, such that a given CPW would not detect the corresponding spin wave at all. For the grating coupler mode with n=9, the wavelength is extremely small compared with the CPW’s signal line width and even smaller than the ...
IT is well known that determinations of the wavelength, λ, of X-ray spectral lines, which have recently been made by means of line gratings, do not agree with those found by crystals, the crystal values being 0.1 to 0.3 per cent less than the line grating values. In this use of line...

X-ray, electromagnetic radiation of extremely short wavelength and high frequency, with wavelengths ranging from about 10^-8 to 10^-12 metre. The passage of X-rays through materials, including biological tissue, can be recorded. Thus, analysis of X-ray i
In the tabletop setup, instead of boiling an electron from a filament, they pluck part of the quantum wave function of an electron from an atom using a very intense laser pulse. The electron is then accelerated andslammed(猛撞,猛砸)back into the ion, releasing its energy as an X-ray ph...
(theK-shell) is raised, by the energising of theatom, to theL-shell and then falls back to theK-shell, a quantum of radiation of wavelengthλ(=1/v¯)is radiated. This is theKα-line. The other lines are emitted as a result of energy changes illustrated inFig. 27.6, theL-series ...
Electromagnetic of wavelength lambda can have similar dimensions with the differences between planes within the crystal's lattice. These correspond to wavelengths in the x-ray spectral range. When x-ray light waves irradiate a crystal at an incident angle theta, they propagate through the crystal ...
