چکیده
Abstract We detail the design of a variable energy, x-ray fluorescence source using low activity (1.8×10 6 dpm) 99 Tc β that irradiates thin foils. By rotating among foils Ti, Zn, Nb, Ag, and Au, device produces x rays between 4 70 keV at rate near 1 Hz. When is placed in storage position, external radiation non-detectable. The shielding rotation mechanism permits use vacuum liquid nitrogen temperature. intended for study energy response to impinging upon Ge detector surfaces. will be useful understanding large-scale arrays such as Majorana LEGEND.

Quantum Electrodynamics of Internal Source X-Ray Holographies: Bremsstrahlung, Fluorescence, and Multiple Energy X-Ray Holography
Quantum electrodynamics (qed) is used to derive the differential cross sections measured in the three new experimental internal source ensemble xray holographies: bremsstrahlung (BXH), fluorescence (XFH), and multipleenergy (MEXH) x-ray holography. The polarization dependence of the BXH cross section is also obtained. For BXH, we study analytically and numerically the possible effects of the vi...
متن کاملInvestigation and Measurement of Ash Content of Coal in Zirab Coal Mine-Iran Using Dual Energy -Ray and X-Ray Fluorescence Methods
Coal with low ash content has an important role in the coal and steel industry. There are different methods to measure the ash content. The conventional method which is used in most coal mines of Iran, is to burn the coal and measure the remaining ash. A new method has been recently developed at Nuclear Research Center (NRC) of Iran, Which works on the basis of the absorption of the dual en...
متن کاملUltrafast Selected Energy X-ray Absorption Spectroscopy (USEXAS) with a Laser-Driven X-ray Source
A laser driven electron x-ray source (LEXS) emitting tungsten Lα lines has been built based on a high repetition rate, terawatt laser system. The Lα characteristic lines overlap with the absorption edge of Ni near 8333 eV. Using this x-ray source, the x-ray absorption spectra near the absorption edge of different Ni compounds have been measured. We term this new method “ultrafast selected energ...
متن کاملX-ray Absorption Spectroscopy Using X–ray Fluorescence Spectrometer
Strong characteristic Kα X-ray lines are accompanied by weak lines due to the radiative Auger effect (RAE) [1, 2]. The characteristic Kα fluorescent X-rays (K-L2,3 lines) are emitted by the 2p→1s electric dipole transition after one of the 1s electron photoionization, Though the probability is less than 0.01, one of the 2p electrons is excited into an unoccupied discrete or continuum level simu...
متن کاملDetermining the Content of Silicon Dioxide in Bauxites Using X-Ray Fluorescence Spectrometry
The X-ray fluorescence spectrometry and the MA.BM.006 reference spectrophotometric methods were used to determine the content of SiO2 (%) in bauxites from different deposits. The treatment of samples prior to the analysis involved the following steps: annealing, melting using the borax method, and the formation of beads. Certified reference bauxite samples were used for the cali...
