Table-Top Water-Window Microscope Using Z-Pinching Capillary Discharge Source
Original language description
We present a new design of a compact transmission water-window microscope based on nitrogen plasma induced by the Z-pinching capillary discharge, operating at wavelength λ = 2.88 nm. The source was built in-house, plasma is generated by a current discharge through alumina capillary filled with nitrogen gas. A ceramic capacitor bank is a pulse charged by a Marx-Fitch generator and switched by self-breakdown spark-gap. Average photons flux is 5.5 x 10^13 photons/(sr x line x pulse), and the plasma spot has a circular shape with diameter of 360 µm at FWHM. The spectrum of soft X-ray radiation produced by the source is filtered by a titanium filter to achieve monochromatic radiation with wavelength λ = 2.88 nm. Filtered radiation is focused by an ellipsoidal nickel-coated condenser mirror. We used a Fresnel zone plate to create an image of a sample transmission on an SXR-sensitive CCD camera. To assess the resolution of the microscope, we imaged a standard sample – copper mesh. The achieved spatial resolution is 75 nm at half-pitch. The images of Desmodesmus cells (Green algae) are presented as well as the description of the sample preparation process.
