" signal detection" . "GA14-22777S" . "The project addresses simulations of interactions of primary and signal electrons with the gas molecules in the low-energy environmental scanning electron microscope and a theoretical and experimental study of the consequences for signal detection. The physical phenomena involved will be simulated using a custom Monte Carlo program which will be developed for work with the pressure gradient of the pumped gas. The program will be tested in the design of an original \u201Clow scattering\u201D differentially pumped chamber, and of a scintillation detector of secondary electrons, both for low-energy ESEM. On the bases of Monte Carlo simulations of interactions of electrons with the solid matter and team\u2019s know hove the limits for detection of backscattered electrons with the energy lower than 2 keV will be studied. Basic research results of native or live biological samples will be enhanced by combination of low energy ESEM, light-optical confocal microscopy and nuclear magnetic resonance and correlation of their data."@en .
