Paper Abstract

From the shot noise consideration in x-ray microscopy it is shown that, for 50 nm resolution, a few tens mJ/cm2 energy of 3 nm x ray is required on the specimen, and required x ray energy density increases with the fourth power of the resolving power. X-ray images of biological specimens in water taken by flash contact microscopy with a laser-plasma source are presented to discuss the prospects of x-ray microscopy for biological applications. Forty nanometer diameter biological components are observed in an x-ray image. The attempt of observing thick specimens by short wavelength x rays produced by a 10 ps duration laser pulse is also reported. Technical issues for further improving contact microscopy, including the feasibility of stereo-microscopy, are discussed.
