Characteristics of Soft X-ray Lens(In Chinese)

Abstract

A soft X-lens was devised with waveguide X-ray optics of total external reflection(TER).The lens consists of a stack of 1 387 TER waveguides with inner diameter of 0.45 mm and outer diameter of 0.60 mm.With the help of plasma sources of soft X-ray radiation,high density of pure soft X-ray radiation (without plasma expansion fragments)with broad-band spectral range can be obtained at the focus of the lens.As laser-plasma is considered,the radiation density of 1.3×10~5 W/cm~2 is obtained,the transmission coefficient is 18.6%, the ratio of the density at the focus with and without the lens is 1 000 and the radiation capture is 28.9°.The density of 0.5 TW/cm~2 can be obtained as far as Qiang-Guang I facility is considered.
