Next generation of Z* modelling tool for high intensity EUV and soft x-ray plasma sources simulations

Influence of CO2-laser pulse parameters on 13.5 nm extreme ultraviolet emission features from irradiated liquid tin target

“…It consists of bright spots because of thermal instability of the critical layer. Such non-uniform distribution of EUV emission under CO 2 -laser irradiation was reported in previous our papers [19] and conference reports [30], also analogous calculated non-uniformities can be seen in [31] and the oscillations in EUV emission were observed in experiment [18]. There are various physical mechanisms of plasma instability at critical layer from Rayleigh-Taylor (RT) to thermal-type.…”

Effect of fast electrons on emission properties of non-equilibrium nitrogen plasma in soft x-ray spectral range

“…Laser produced plasma (LPP) is derived through an interaction of focused single or multiple laser pulses (of the same or different wavelengths) with a solid or liquid target [7,8], or gaspuff target [1] in a vacuum chamber; for discharge produced plasma (DPP), it is an electric discharge in a capillary filled with a gas mixture [9][10][11] or vacuum arc [12]. The only way to use the discharge technique with solid or liquid targets to obtain ionized plasma is with the combined approach: initially a laser pulse vaporizes and preionizes the target, setting up an arc discharge as the main driver of plasma heating [12][13][14].…”
