Improved X-ray microscopic imaging

Menzel. "We can even characterize fluctuations of the sample itself, even if they are much too fast to be seen with individual snapshots."

"We needed to convince ourselves that the images we produced did indeed reflect accurately the samples and their dynamics," says Pierre Thibault. "So we carried out computer simulations. They confirmed that effects of the instrument as well as of the sample itself, such as flows, switching events or mixed quantum states, can be characterized."

The new method combines the characterization of dynamical states with high-resolution X-ray microscopy. One possible application is to analyze the changing magnetization of individual bits in magnetic storage media with high storage density. The interactions of such single magnetic bits or their thermal fluctuations, which ultimately determine the lifetime of magnetic data storage, could be visualized.

"In addition to its use in imaging," explains Pierre Thibault, "our analysis method also reveals a fundamental relationship to other disciplines: Microscopy and scientific disciplines such as quantum computing, previously regarded as independent, can benefit from each other here."
