A High-resolution X-ray Microscope
92 LLE Review, Volume 74 A soft x-ray microscope (E & 3 keV) with high spatial resolution (~3 μm) has been characterized at LLE and used for initial experiments on the OMEGA laser system to study the hydrodynamic stability of directly driven planar foils. The microscope, which is an optimized Kirkpatrick-Baez (KB)–type design, is used to obtain four x-ray radiographs of laser-driven foils. Time...
متن کاملA Full Field Transmission X-ray Microscope as a tool for High-Resolution Magnetic Imaging
The XM-1 soft x-ray microscope is a user-dedicated facility located at the Advanced Light Source at Lawrence Berkeley National Laboratory and has recently been established as a tool for high-resolution imaging of magnetic domains. It is a conventional full field transmission microscope which is able to achieve a resolution of 25 nm by using high-presicion zone plates. It uses off-axis bend magn...
متن کاملHigh resolution hard x-ray spectroscopy of femtosecond laser-produced plasmas with a CZT detector
We present measurement of characteristic Ka emission from Mo, Ag, and La targets irradiated by a 60 fs, 600 mJ, 10 Hz Ti:sapphire laser pulse at 10– 10 W/cm. These x-ray emissions can potentially be used in applications from laser-based hard x-ray sources to x-ray mammography so detailed knowledge of the spectra is required to assess imaging of the figure of merit. We show here that high resolv...
متن کاملHigh-resolution spatial characterization of laser produced plasmas at soft x-ray wavelengths
In this article, we describe the setup and application of a system for the spatial characterization of laser-produced plasma x-ray sources. While pinhole cameras are normally used for this purpose, we employed a zone plate to act as the x-ray lens. Together with an x-ray CCD camera as the detector, a spatial resolution of up to 2 μm was achieved. Due to the wavelength-dependent focal length of ...
متن کاملCharacterization of Laser Plasmas for an X-Ray Backlighter
The investigation of the inner core of dense, cool plasmas is due to the high opacity and weak self emission a difficult issue. A powerful diagnostic tool for these plasmas is an X-ray backlighter [1]. For this experimental setup a laser plasma is used as an intense X-ray source to either shadowgraph [2] the plasma or to do absorption spectroscopy [3]. This setup allows a high temporal resoluti...
