Scanning microscopy with electrons and x-rays.
The principle of sequential imaging, by means of a signal generated with an electron probe scanning the specimen in a regular raster, has been successfully developed into the form of practical microscopes during the past few years. The scanning electron microscope has been constructed first, but it was slow to find its proper fields of application. Now it is proving valuable primarily in solid ...
متن کاملThymidine decomposition induced by low-energy electrons and soft X rays under N2 and O2 atmospheres.
A novel technique has been employed to investigate the simultaneous damage to DNA components induced by soft X rays (1.5 keV) and low-energy electrons (0-30 eV) in thin films of thymidine deposited on glass and tantalum substrates and irradiated under atmospheric pressure and temperature. The films were surrounded by either an N2 or O2 environment. The formation of four radiation-induced produc...
متن کاملQuantitative evaluation of radiation damage to polyethylene terephthalate by soft X-rays and high-energy electrons.
The chemical changes and absolute rates in radiation damage to polyethylene terephthalate (PET) caused by soft X-rays and energetic electrons have been measured using a scanning transmission X-ray microscope (STXM). Electron beam damage at two different dose rates and a range of doses was performed in an 80 keV transmission electron microscope (TEM). The STXM beam was used to create damage patt...
متن کاملOutrunning damage: Electrons vs X-rays—timescales and mechanisms
Toward the end of his career, Zewail developed strong interest in fast electron spectroscopy and imaging, a field to which he made important contributions toward his aim of making molecular movies free of radiation damage. We therefore compare here the atomistic mechanisms leading to destruction of protein samples in diffract-and-destroy experiments for the cases of high-energy electron beam ir...
متن کاملInverse Compton X-rays from relativistic flare electrons and positrons
Context. In solar flares, inverse Compton scattering (ICS) of photospheric photons might give rise to detectable hard X-ray photon fluxes from the corona where ambient densities are too low for significant bremsstrahlung or recombination. γ-ray lines and continuum in some large flares imply the presence of the necessary ∼ 100 MeV electrons and positrons, the latter as by-products of GeV energy ...
