Development of laser driven high-brightness fast x-ray sources is a key application of the PHELIX laser for experiments in combination with the heavy ion accelerator. X-ray diagnostics of high-energy density states of matter produced with intense heavy ion beams from GSI or FAIR will require multi-keV x-ray energies to penetrate the dense plasma [1]. Recent development of backlighter sources at...
The radiations from 60-day Sb lN have been studied by several investigators. H ales and Jordan [2] used a 1800 spectrometer to study the beta spectrum of Sb124. Tbey report the presence of two components with maximum cnergies at 0.74 ± O.03 and 2.45 ± 0.07 million electron volts (NIev) . ~1iller and Omtiss [3], u ing a thin magnetic len spectrometer , also ob erved a complex beta specLrum, but ...
a facile co-precipitation method for the synthesis of well-dispersed ndfeo3 nanocrystals is developed in the presence of octanoic acid as surfactant. co-precipitation can produce fine, high-purity, stoichiometric particles of single and multicomponent metal oxides. the product is characterized by fourier transform infrared spectroscopy (ft-ir), x-ray diffraction (xrd), scanning electron microsc...
A cryogenic microcalorimeter x-ray spectrometer is coupled to an FEI XL30 environmental scanning electron microscope (ESEM). The microcalorimeter is designed to obtain high resolution broadband xray spectra in the energy range of 150 eV to 10 keV. An x-ray optic enhances the solid angle for x-ray energies between 150 eV and 2300 eV. This enables precise microanalysis with relatively low energy ...
Recent technological developments and new topology designs have made semiconductor drift detectors ideal devices for high-resolution x-ray spectrometry. In this paper the basic topology of a semiconductor drift detector with on-chip electronics specially designed for x-ray spectrometry is reviewed. These devices have been used for the first time in x-ray and g-ray spectroscopy applications. In ...
X-ray free-electron lasers (XFELs) open up new possibilities for X-ray crystallographic and spectroscopic studies of radiation-sensitive biological samples under close to physiological conditions. To facilitate these new X-ray sources, tailored experimental methods and data-processing protocols have to be developed. The highly radiation-sensitive photosystem II (PSII) protein complex is a prime...
