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 کاملChemically Sensitive Tomography at 50 nm Spatial Resolution using a Soft X- ray Scanning Transmission X-Ray Microscope
Previous very successful soft X-ray microscopy tomography experiments [1-3] have been performed at a single photon energy. They have provided high spatial resolution, density based 3D images, but with only limited chemical information. We are developing computed angle-scan tomography in a scanning transmission x-ray microscope (STXM) for chemical visualization of a 3D spatial volume. Our goal i...
متن کاملProgress toward a Soft X-ray Fel
The recent successes in operating FELs from the far infrared to the visible and near UV [1], together with a better understanding of the physics and technology of these systems, are leading us to explore again the possibility of using FELs to produce coherent radiation in the XUV region, at wavelength shorter than 100 nm . In this paper we derive a set of scaling laws, which we will use to stud...
متن کاملSoft-x-ray projection lithography
Soft-x-ray projection imaging is demonstrated by the use of 14-nm radiation from a laser plasma source and a single-surface multilayer-coated ellipsoidal condenser. Aberrations in the condenser and the Schwarzschild imaging objective are characterized and correlated with imaging performance. A new Schwarzschild housing, designed for improved alignment stability, is described.
متن کاملkeV SOFT X-RAY BACKGROUND
Snowden and coworkers have presented a model for the 1 4 keV soft X-ray diffuse background in which the observed flux is dominated by a ∼ 10 K thermal plasma located in a 100–300 pc diameter bubble surrounding the Sun, but has significant contributions from a very patchy Galactic halo. Halo emission provides about 11% of the total observed flux and is responsible for half of the H I anticorrela...
