Abstract Bremsstrahlung spectra produced by 5 keV electrons incident on Al2O3 and MgO targets at air pressures of 30, 50, 100 Pa have been compared with results using pyPENELOPE, a program designed to simulate electron microscopy. The comparisons showed that the experimental were in good agreement simulated except near Duane–Hunt limit, where bremsstrahlung amplitudes consistently greater than ...
A male patient in his 20s presented at our clinic with pain caused by bone metastases of the primitive neuroectodermal tumor, and Sr-89 was administrated to palliate the pain. After receiving the injection, the patient complained of a slight burning pain at the catheterized area. Slight reddening and small circular swelling (diameter, 0.5 cm) were observed at the catheterized area. Sr-89 extrav...
We describe a work in progress on the reconstruction of radial profiles for the ion effective charge Z eff on the TEXTOR tokamak, using statistical data analysis techniques. We introduce our diagnostic for the measurement of bremsstrahlung emissivity signals. Z eff profiles can be determined by Abel-inversion of line-integrated measurements of the bremsstrahlung emissivity (ǫ ff) from the plasm...
The sudden deflection of an electron by the Coulomb field of nuclei can cause the electron to radiate, producing a continuous spectrum of x-rays called bremsstrahlung. The fraction of electron energy converted into bremsstrahlung increases with increasing electron energy and is greater for media of high atomic number. (This process is important in the production of x-rays in conventional x-ray ...
Isolated lepton momenta, in particular their directions are the most precisely measured quantities in pp collisions at LHC. This offers opportunities for multitude of precision measurements. It is of practical importance to verify if precision measurements with leptons in the final state require all theoretical effects evaluated simultaneously or if QED bremsstrahlung in the final state can be ...
