Abstract
Soft x-ray radiation is being widely applied in many branches of science and technology. It can be assumed, that this radiation fills the gap between optical- and electron microscopy. Soft x-ray technology showed its attractiveness for diagnostics of living cells and biological tissues. The main task of these diagnostics is observation of cells of typical dimensions of 20-40 nm or even less ones (DNA structures). Currently available diagnostic technologies do not provide a sufficient resolution and request a special preparation procedure of investigated materials. Using the radiation in the range of 2-4 nm (called “water window” region), the described restrictions are minimized.
Analysis of the market shows that there is no commercial available energy meter operated at the water window range. The paper presents an approach of such detection head designed in the Institute of Optoelectronics MUT. The preliminary results of analysis and the experimental investigations of the head are described.
