Compact focusing von Hamos spectrometer for quantitative x-ray spectroscopy
A compact focusing crystal spectrometer based on the von Hamos scheme is described. Cylindrically curved mica and graphite crystals with a radius of curvature of Rϭ20 mm are used in the spectrometer. A front illuminated charge-coupled device ͑CCD͒ linear array detector makes this spectrometer useful for real-time spectroscopy of laser-produced plasma x-ray sources within the wavelength range of ...
متن کاملA von Hamos x-ray spectrometer based on a segmented-type diffraction crystal for single-shot x-ray emission spectroscopy and time-resolved resonant inelastic x-ray scattering studies.
We report on the design and performance of a wavelength-dispersive type spectrometer based on the von Hamos geometry. The spectrometer is equipped with a segmented-type crystal for x-ray diffraction and provides an energy resolution in the order of 0.25 eV and 1 eV over an energy range of 8000 eV-9600 eV. The use of a segmented crystal results in a simple and straightforward crystal preparation...
متن کاملX-RAY FOCUSING CRYSTAL VON HAMOS SPECTROMETER WITH A CCD LINEAR ARRAY AS A DETECTOR, A. Shevelko, L. Knight, Q. Wang, O. Yakushev, P.N. Lebedev, pp. 433-440
An x-ray focusing crystal von Hamos spectrometer was developed using mica and graphite cylindrical crystals (radius of curvature R=20 mm) with a CCD linear array detector. The commercial CCD (Toshiba model TCD 1304AP) used for x-ray detection has 3724 pixels (8 μm width and 200 μm height) giving a total length of ~30 mm. The CCD detector was absolutely calibrated using laser-produced plasmas. T...
متن کاملA multi-cone x-ray imaging Bragg crystal spectrometer.
This article describes a new x-ray imaging Bragg crystal spectrometer, which-in combination with a streak camera or a gated strip detector-can be used for time-resolved measurements of x-ray line spectra at the National Ignition Facility and other high power laser facilities. The main advantage of this instrument is that it produces perfect images of a point source for each wavelength in a sele...
متن کاملThe NEAR X-Ray/Gamma-Ray Spectrometer
he X-Ray/Gamma-Ray Spectrometer on the Near Earth Asteroid Rendezvous (NEAR) spacecraft will remotely sense X-ray and gamma-ray emissions from the surface of near-Earth asteroid 433 Eros and look for characteristic “signatures” in those emissions to determine its elemental composition. During the planned 10 months of orbits about Eros beginning in early 1999, data returned from the instrument w...
