Název v původním jazyce

Development of a compact laser-produced plasma soft X-ray source for radiobiology experiments

Popis výsledku v původním jazyce

A desk-top laser-produced plasma (LPP) source of soft X-rays (SXR) has been developed for radiobiology research. The source is based on a double-stream gas puff target, irradiated with the focused beam of a commercial Nd:YAG laser. The source has been optimized to get a maximum photon emission from LPP in the X-ray ?water window spectral wavelength range from 2.3 nm (i.e., an absorption edge of oxygen) to 4.4 nm (i.e., an absorption edge of carbon) (280?540 eV in photon energy units) by using argon gas-puff target and spectral filtering by free-standing thin foils. In this paper, the source design, radiation output characterization measurements and initial irradiation experiments are described. The source can be useful in addressing observations related to biomolecular, cellular and organisms? sensitivity to pulsed radiation in the ?water window, where carbon atoms absorb X-rays more strongly than the oxygen, mostly present in water.
