Development of a Soft X-ray Microprobe for Radiobiology Studies

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...

Soft-x-ray fluorescence studies of solids

Resonant inelastic x-ray scattering (RIXS) has been observed in many systems above and below their core threshold. Below threshold, inelastic-loss features are observed, which disperse linearly with excitation energy, but as the excitation increases above the core binding energy, in general nonlinear dispersive effects are observed. These two effects are described by the same physics of coheren...

VI-A-1 Development of a Transmission-Grating Spectrometer for Soft-X-Ray Emission Studies

Last year we reported our new design of a transmission-grating spectrometer (TGS) for high resolution soft X-ray emission stuides. This spectrometer will realize a resolution E/∆E up to 5000 in the energy region of 50– 600 eV. Here we report the first results using a prototype setup. The spectrometer has a Wolter type I mirror, a free-standing transmission grating, and a back-illuminated charge...

A Variable-Energy Soft X-Ray Microprobe to Investigate Mechanisms of the Radiation-Induced Bystander Effect

There remains a need to improve our understanding of the hazards that arise through occupational and environmental exposures to ionizing radiations. An important aspect of this is the role of non-targeted effects (such as the bystander effect) in the biological response to low dose exposures. Micro-irradiation techniques have become an important method for radiobiolical studies of low-dose effe...
