X-rays are electromagnetic waves with wavelengths of 0.1 to several 10 nm and energies of 0.1–100 keV (Fig. 1). X-rays with the shorter wavelengths are called hard X-rays and have a high transmission ability, while X-rays with the longer wavelengths are called soft X-rays. Usually, X...
In this new tube, thermal electrons emitted from a hot filament hit the target, which was an emission source of X-rays (1913) [8].Following the investigation of the properties of X-rays by Barkla, Mose- ley studied characteristic X-rays in an exchange of communications with...
Excessive poverty is probably more prevalent in the U. S. than in any of the countries that have a better infant mortality rate and female life expectancy at birth. This is probably true also for all but four or five of the countries with a longer male life expectancy. In the notably ...
the above-mentionedψrotations) have been found to be inconsistent with purely stochastic processes12,13. This indicates that there is some coherent ordering of the magnetic field, for example, by compression or amplification by plasma processes in shocks14or by the presence ...

The paper “Reflection of X-rays from a rough surface at extremely small grazing angles” https://doi.org/10.1364/OE.23.024220 was very useful in getting the basic reflectivity code working initially. The following ~book contains an introduction about reflectivity, including the derivation of the ...
(LHPs) have shown promising material properties for X-ray detection, such as containing heavy elements (Pb and I) and highμτproducts, yielding effective X-ray detectors4,5,6,7. However, LHPs suffer from ion migration, limiting the range of biases that can be applied to the detectors4,...
Which of the following types of radiation has the highest energy? a. \alpha-particles b. \beta-particles c. \gamma -rays d. visible light e. All of these have the same energy. Which kind of electromagnetic radiation contains the greatest energy per photon? a) Microwaves b) Gamma rays ...
Optical pulses are routinely used to drive dynamic changes in the properties of solids. In quantum materials, many new phenomena have been discovered, including ultrafast transitions between electronic phases, switching of ferroic orders and non-equilibrium emergent behaviours, such as photoinduced superco...
Impact strength of the lead glass is also low and losses often result, due to lack of sufficient resistance to impact. The use of sheet lead is limited, due to its low melting point, to the lining of X-ray booths and difficulties are encountered due to the creeping properties of the ...
