Tomographic imaging with the use of a compact soft X-ray microscope based on a laser plasma light source

摘要

A desktop tomography system, based on laser-interaction with a gas puff target, which results in efficient plasmaformation emitting in the soft X-ray (SXR, λ = 0.1 - 10 nm) region, was developed at IOE-WAT (Warsaw, Poland).The system, coupled with an ellipsoidal condenser and a Fresnel zone-plate and working in the "water window" spectralrange (λ = 2.3 - 4.4 nm) at the quasi-monochromatic He-like nitrogen spectral line (λ=2.88nm), allows acquiring imagesapproaching a resolution of few microns. The development of such setup offers the possibility to obtain a reconstructionof three-dimensional images in a laboratory environment, without the involvement of large "photon facilities". Detailsabout the system and its optimization as well as some imaged samples will be presented and discussed.
