Project Title

Laboratory tomographic microscopy with compact plasma based extreme ultraviolet and soft x-ray sources

Abstract

Microscopy using the Soft X-ray (SXR) and Extreme Ultraviolet (EUV) radiation is a very promising technique in micro- and nano-structure imaging. It can provide quality images of cells and its organelles and information of the chemistry of proteins and other bio-molecules. This is possible because of the so called ‘water window’ interaction of light with wavelength from 2.3 – 4.4 nm.

The typical SXR and EUV radiation sources for Tomographic Microscopy are Synchrotron Accelerators. These sources are quite expensive and not accessible to everyone in a typical research laboratory. Hence, there is a need for a compact, practical and less expensive source of SXR and EUV. A recently developed Compact SXR EUV source based on Gas-discharge Plasma were developed by Bergmann, K. et al.

Two dimensional images of biological cells have been produced with nanometer resolution. By rotating the sample, it is possible that a tomographic images can be acquired. This is done through an algorithm similar to the principle behind Computed Tomography X-ray machines. Two dimensional projection images can be reconstructed to produce a three dimensional image or tomography image.
