Özet

Laser-produced plasmas can be used as extreme ultraviolet (EUV) sources for lithography, operating in the 13.5 nm range. Soft X-rays emitted from laser-produced tin plasma were simulated using the EHYBRID code. Required atomic data for tin ions were calculated using the Cowan code. In the EHYBRID simulations tin stab target is assumed to be irradiated by 1064 nm wavelength Nd:YAG laser. Simulations were performed for different driving laser parameters.
