    "abstract": "High-energy bremsstrahlung and K X-rays were used to produce nearly\nbackground-free K X-ray spectra of up to 87 keV (Pb) via X-ray fluorescence.\nThe fluorescing radiation was produced by electron accelerators, consisting of\nheated and cooled cylindrical LiTaO3 and LiNbO3 crystals at mTorr pressures.\nThe newly discovered process of gas amplification whereby the ambient gas\npressure is optimized to maximize the electron energy was used to produce\nenergetic electrons which when incident on a W/Bi target gave rise to a\nradiation field consisting of high-energy bremsstrahlung as well as W and Bi K\nX-rays. These photons were used to fluoresce Ta and Pb K X-rays.",
