“…Electron beams with kinetic energies ranging from 2.5 keV to 30 keV were generated from the electron gun of a refitted scanning electron microscope (SEM) of KYKY-2800B type (KYKY Technology Co., Ltd, Beijing, China). The redesigns and modifications of the deep Faraday cup made by Zhao et al [25,26] are very useful, as a result of these modifications we have achieved more accurate experimental data. The electron beams are well focused and impact the targets at a 45-degree angle through the top hole of the redesigned Faraday cup.…”

“…The experiments were performed at the Institute of Nuclear Science and Technology of Sichuan University. The experimental instruments are the same as that in Zhao et al [25,26]. Electron beams with kinetic energies ranging from 2.5 keV to 30 keV were generated from the electron gun of a refitted scanning electron microscope (SEM) of KYKY-2800B type (KYKY Technology Co., Ltd, Beijing, China).…”

“…Details of the detection efficiency of this SDD detector was described in Zhao et al [26]. In order to get an accurate inner-shell production cross section, we must get reliable values of the SDD detector efficiency.…”

“…A thin Al film on thick carbon substrate target was also used to compare the results with a self-supporting monoatomic and grid carbon target. In addition, for the L-shell ionization cross-sections or x-ray production cross-sections of lower-and medium-Z elements, the measurements are relatively scarce and significant differences exist between the theoretical models and the experimental data from different authors [1,25,26,[29][30][31]. Furthermore, to the best of our knowledge, there are no experimental data for Se L-shell published till now.…”

“…Therefore, it is still necessary to find these measurements. In this paper, an improved experimental setup has been used [25,26]. As we know, Al is widely used in practical applications and in research areas, and in the energy region of keV some experimental data of Al K-shell ionization cross sections have been published (a target of selfsupporting thin films was adopted in Hink et al [27] and a target of thin films on substrates was used in Limandri et al [28]).…”

The K-shell ionization cross sections of Al (Z = 13) and the total L-shell x-ray production cross sections of Se (Z = 34) from electron impacts with kinetic energies ranging from several keV to several tenths of keV have been measured by using an improved experimental setup. An Al target of monoatomic and grid carbon substrate, which consisted of ultrathin Al film (∼3 nm) deposited onto grid carbon substrate (∼200 nm) with a layer of monoatomic carbon between the film and the grid substrate, was first proposed and measured. In addition, targets of Al film (∼3 nm) and Se film (∼7.8 nm) deposited respectively onto thick carbon substrate (∼2 mm) were also measured. Our experimental results are compared with the distorted-wave Born approximation (DWBA) theory and experimental data from the literature. It has been observed that within the uncertainties, the DWBA agrees with our experimental measurements of K-shell ionization cross sections of Al and the total L-shell x-ray production cross sections of Se, and our measured data of Al K-shell ionization cross sections are consistent with the available experimental data. This is the first time that experimental data of Se-L-shell x-ray production cross sections in the intermediate-energy region have been published.
