X-ray emission spectrum of a hot plasma

X-ray Emission from Hot Gas in Galaxy Mergers

We examine X-ray emission produced from hot gas during collisions and mergers of disk galaxies. To study this process, we employ simulations that incorporate cosmologically motivated disk-galaxy models and include the effects of radiative cooling, star formation, supernova feedback, and accreting supermassive black holes. We find that during a merger, the colliding gas in the disks is shock-hea...

A proton induced X-ray emission (PIXE) analysis of concentration of trace elements in varicose veins

Background: Proton induced X-ray emission (PIXE) has been applied as reliable and improved techniques in this study to compare concentration of various trace elements in normal and abnormal varicose veins. Materials and Methods: Five samples from normal veins and 13 samples from varicose veins bombarded by 2.0 MeV energy proton beams produced by a Van de Graff accelerator in vacuum. T...

X-ray emission from betatron motion in a plasma wiggler.

The successful utilization of an ion channel in a plasma to wiggle a 28.5-GeV electron beam to obtain broadband x-ray radiation is reported. The ion channel is induced by the electron bunch as it propagates through an underdense 1.4-meter-long lithium plasma. The quadratic density dependence of the spontaneously emitted betatron x-ray radiation and the divergence angle of approximately (1-3)x10...
