    Comparison of Laser Produced Plasma and Discharge Produced Plasma as a Source for Soft X-Ray Microscopy

  • Original language description

    We compare two table top sources of extreme ultraviolet (XUV) radiation - laser produced plasma (LPP) and discharge produced plasma (DPP), with regard to cell imaging in the soft x-ray regime. Nitrogen plasma is ideal for monochromatic radiation with wavelength ? = 2.88 nm, which corresponds to the quantum transition 1s2-1s2p of helium like nitrogen ion. This wavelength is located in the water-window region, thus it provides the natural contrast between water and carbon-based substances, e.g. proteins.LPP source was developed in Laser-Laboratorium Göttingen e.V., Germany, plasma was generated by Q-switched Nd:YAG laser (? = 1064 nm, 600 mJ, 7 ns pulse) focused into nitrogen gas-puff target. The typical photons flux was 6x1011 photons/(sr x line x pulse) for input nitrogen pressure p = 12 bar. The size of the plasma spot was 0.2 x 0.4 mm. DPP source was built in-house, plasma was generated by a current discharge through a 10 cm long, 3.2 mm inner diameter ceramic capillary filled with
