Damage study of irradiated tungsten and copper using proton and argon ions of a plasma focus device

Mechanical behavior of ion-irradiated ODS RAF steels strengthened with different types of refractory oxides

“…Displacement of the peaks from their original positions and their shape fluctuation may have various reasons. Broadening of the diffraction signal occurs when there is a loss of crystallinity [35]. Hence, the more crystal defects are created, the broader the peak becomes.…”

“…Hence, the more crystal defects are created, the broader the peak becomes. Furthermore, the deviation of the diffraction peak from its 2θ position is strictly related to the change in the inter-planar distance d [35]. Both effects (peak shifts and broadening) may occur independently, although one effect may intensify the other.…”

“…It is known that modifications of the diffraction peak shape and position is related to alteration of the crystal structure. Increasing inter-plane distance d is manifested by decreasing 2θ value [35], whereas broadening of the peak is related to lowering the crystals' size through the Debye Scherrer equation [36]. Detailed investigation of peaks' shifts and their broadening allows for the calculation of lattice parameters and microstrain, as presented in work [37].…”

Investigation of Optical Properties and Chemical Structure of Nd2O3 Nanoparticles Deposited on NaX Zeolite Powder Using Plasma Focus Device

“…In addition, there are some metastable higher lying levels resulting in visible strong emissions. The rare-earth oxide has been attracted much attention because of its high band gap (5.8 eV), high dielectric constant (10)(11)(12)(13)(14)(15), favorable lattice matching, and proper thermodynamic stability in conditions of contact with silicon substrates. For these reasons, several studies have been focused on neodymium doped materials and their possible applications in related telecommunication and laser facilities such as optical ampli ers and solid state lasers [4][5][6][7][8].…”

“…The organization of the paper is as follows: In Sec. [15][16][17][18][19][20].The MTPF device of present study, as is shown schematically in Fig. 1, has 5.3 kJ energy and is powered by a 12µF, 30kV fast discharging energy storage capacitor.…”
