Optimum driving a Z-pinch for soft X-Ray lasers
A capillary plasma z-pinch as an alternative active medium of soft X-Ray lasers was studied experimentally and theoretically. The theoretical analysis was based on the self consistent solution of the so called “snow plow” model. The dynamics of pinched plasma is determined by the capillary parameters and by the time dependence of electrical current passing through it. The current time dependenc...
متن کاملCluster analysis of soft X-ray spectromicroscopy data.
Soft X-ray spectromicroscopy provides spectral data on the chemical speciation of light elements at sub-100 nm spatial resolution. When all chemical species in a specimen are known and separately characterized, existing approaches can be used to measure the concentration of each component at each pixel. In other cases (such as often occur in biology or environmental science), some spectral sign...
متن کاملCharacterization of Biomaterials by Soft X-Ray Spectromicroscopy
Synchrotron-based soft X-ray spectromicroscopy techniques are emerging as useful tools to characterize potentially biocompatible materials and to probe protein interactions with model biomaterial surfaces. Simultaneous quantitative chemical analysis of the near surface region of the candidate biomaterial, and adsorbed proteins, peptides or other biological species can be obtained at high spatia...

متن کاملX-Ray Absorption Spectromicroscopy of Aqueous Samples
X-ray PhotoElectron Emission Microscopy (X-PEEM) has found numerous applications in the surface microchemical analysis of materials science and biological specimens. We have reconfigured the MEPHISTO X-PEEM instrument, installed at the UW-Synchrotron Radiation Center, to measure true x-ray transmission spectra by converting transmitted photons to photoelectrons via a thin photocathode layer of ...
