The continuous spectra consists of a range of wavelengths of X-rays with minimum wavelength and intensity (measured in counts per second) dependent on the target material and the voltage across the Xray tube. Since the energy differences between electrons in the various energy levels is a characteristic of the target atom. but the wavelengths of the characteristic Xrays remain unchanged. …. The output spectrum consists of a continuous spectrum of X-rays, with additional sharp peaks at certain energies. The continuous spectrum is due to bremsstrahlung, while the sharp peaks are characteristic X-rays associated with the atoms in the target. For this reason,

The characteristic spectra consists of definite wave lengths superimposed on the continuous spectrum. ‘continuous’ X-rays come from ‘brehmstrahlung’ (‘braking radiation’) as the high energy electrons approach the nucleus of a heavy metal. Since the electron could come very close to the nucleus (and give up a lot of energy to the production of an X...

Abstract Under the assumption that the target of an x-ray tube is a plane mirror which completely reflects the electron waves, the characteristics of the continuous x-ray spectrum are deduced from the principles of wave-mechanics. It is with this continuous x-ray spectrum that we shall be concerned.

continuous spectrum represents 30 to 70% of the total intensity which is composed of this continuous spectrum and the anode’s characteristic lines. It is surprising that it was long considered that the continuous spectrum was described by the Kramers’ law, while this law concerns the x-ray inner generation by electrons and not the x-rays leaving the anode or tube’s window.

The continuous X-ray spectral profiles have been successfully produced using the excited dental X-ray tube, where used dental X-ray tube was employed in the experimental setup. The unfiltered beam is a typical continuous X-ray spectrum rising to a broad maximu= around 100-130 keV. Accompanying the continuous distribution is the characteristic radiation for tungsten photons at around 60 keV arising from the transition of excited atoms to lower energy levels. The 0.6 m Cu filter selectively reduces the intensity at the expense of lower energies and shifts the

Characteristic X-rays can be used to identify the particular element from which they are emitted. This property is used in various techniques, including X-ray fluorescence spectroscopy, particle-induced X-ray emission, energy-dispersive X-ray spectroscopy, and wavelength-dispersive X-ray spectroscopy. This paper is concerned with simple methods of determining the spectral distribution in the continuous X-ray spectrum. After a brief reference to the salient factors concerning the intensity-distribution, a method of analysis put forward by Silberstein and based on filtration data is critically examined, and it is shown that, provided reliable
