Accurate Wavelength Measurements and Modeling of Fexvto FexixSpectra Recorded in High‐Density Plasmas between 13.5 and 17 A

A brief review of the intensity of lines 3C and 3D in neon-like Fe XVII

“…However, because of the relatively high densities (n e ∼ 10 19 cm −3 ), and the fact that several charge states are present simultaneously, the low ratios might result from opacity effects and possibly line blending with X-ray emission from other charge states. Fe XVII has also been observed in laser produced plasmas [32][33][34][35]; however, those suffer the same problems of high density and presence of many ions as found in vacuum spark plasmas. For example, figure 1 shows 3 different spectra measured from laser produced plasmas at Tor Vergata University [35], where lower charge states are present and opacity effects play a role .…”

Spectroscopy Methods and Applications of the Tor Vergata Laser‐Plasma Facility Driven by GW‐Level Laser System

“…A specific stepped rotating target configuration [19], consisting of two separate targets at a distance of (300-800) μm, has been also used in all experimental tests. More exactly, the first component was constituted by BaF 2 (i.e., the investigated target), while the second part contained Mg or Al used to produce reference spectral lines.…”

“…More precisely, in the field of laser-induced plasmas, the main applications [7,8] concern the traditional area of inertial confinement fusion [9,10], astrophysics [11,12], X-ray spectroscopy [4,[13][14][15][16][17][18][19][20], X-ray imaging [4,[21][22][23], quantum electrodynamics and high-energy physics [24][25][26], atomic physics [27], solid-state physics [28], conversion efficiency studies from laser radiation to UV or X-rays [4,5], evaluation of the energy of the radiation backscattered by plasma and of its reflectivity [4], and so on.…”

“…In this paper the attention will focus on a specific laserplasma source (TVLPS), installed and actually operating at the Quantum Electronics and Plasma Laboratory of the Tor Vergata University (Rome, Italy), based on a high-intensity, GW-level, multistage, pulsed, tabletop Nd:YAG/Glass laser. Specifically, in this paper some results and applications of this laser-plasma source are given concerning soft X-ray spectroscopy [18][19][20] and imaging, especially in the field of the microradiographies of thin biological samples [23].…”

“…For example, X-ray emission spectra both of He-like and Ne-like ions have been used as diagnostic tool for several types of plasmas, such as those of astrophysical interest [19]. Significant information in the field of plasma physics have been also obtained by means of model calculations and measurements of the X-ray emission spectra of a barium (Ba) plasma in spectral range of high-n (principal quantum number) Rydberg levels in a near Ni-like Ba XXIX ionization state [20] and by the analysis of high-n dielectronic Rydberg satellites in the near Ne-like Zn XXI ion spectra from Mg-like Zn XIX and Na-like Zn XX ions [18] (Section 4).…”
