Production and Measurements of X-rays (Theory ...

Most widely used X-ray source is from X-ray tube, on which X-rays are produced when high speed electrons collide with a metal target. As electrons collide with atoms in the target and slow down, a continuous spectrum of x-rays are emitted. The high energy electrons also eject inner shell electrons in atoms through the ionization process.

Abstract - Harvard University

Our purpose is to obtain a deeper determination of the bulk composition bombarding with 18 MeV protons through the corroded samples surfaces, without polishing the ancient object. To check this methodology high energy PIXE has been performed on two fibulae of the Later Bronze Age and First Iron Age, coming from the area around Sevilla.

Abstract Thin films (d ∼ 1 μm) of hydrogenated amorphous silicon carbide (a-Si 1-x C x:H), deposited by RF reactive magnetron sputtering with different carbon content x, have been implanted with high fluences (Φ = 1016-1017 cm-2) of high-energy (E = 0.2-1 MeV) He + ions as the implant species. The induced structural modification of the implanted material results in a considerable change of ...

Hi-NRG - Wikipedia

Hi-NRG (pronounced "high energy") is a genre of uptempo disco or electronic dance music (EDM) that originated in the United States during the late 1970s and early 1980s.. As a music genre, typified by a fast tempo, staccato hi-hat rhythms (and the four-on-the-floor pattern), reverberated "intense" vocals and "pulsating" octave basslines, it was particularly influential on the disco scene.
