چکیده
Soft X-ray spectroscopy of the Sun is an important tool to understand coronal dynamics and composition. The solar spectrum below 1 keV least explored with high-resolution spectroscopy. Recent observations Hinode XRT using coarse along imaging have shown that abundances in coronae variability associated structures on Sun. Disk averaged better spectral resolution spectrometers show time flares. Both spatial temporal variabilities seem be related changes magnetic field topology. Understanding such short term necessary model underlying mixing material between different layers A Sensitive spectrometer covers range plasma temperatures emission line complexes would uniquely reveal entire evolution We are investigating a design multi-layer mirror-based spectrograph from 0.5 7 keV. instrument operates four asynchronous channels operating one at time. mirror placed focus Wolter type I telescope reflects narrow band X-rays CCD which Nasmyth defocus. Converging front end optics helps increase each channel while preserving resolution. This estimated achieve 20 eV 0.5–7 With high resolution, we can resolve individual features e.g., 6.7 Fe complex used diagnose high-temperature transient during performance science capabilities this will discussed detail paper.

Highly efficient beamline and spectrometer for inelastic soft X-ray scattering at high resolution.
The design, construction and commissioning of a beamline and spectrometer for inelastic soft X-ray scattering at high resolution in a highly efficient system are presented. Based on the energy-compensation principle of grating dispersion, the design of the monochromator-spectrometer system greatly enhances the efficiency of measurement of inelastic soft X-rays scattering. Comprising two bendabl...
متن کاملHigh-resolution x-ray analysis with multilayer gratings
Periodic multilayers are nowadays widely used to perform x-ray analysis in the soft x-ray range (photon energy lower than 1 keV). However, they do not permit to obtain highresolution spectra like natural or synthetic crystals. Thus, multilayers cannot resolve interferences between close x-ray lines. It has been shown and demonstrated experimentally that patterning a grating profile within a mul...
متن کاملTunable multilayer EUV/soft x-ray polarimeter
A tunable polarimeter using multilayer interference coatings as both reflection polarizer and transmission phase retarder is described. The portable device bolts onto existing chambers and its rotation axis is precisely aligned to the beam. The upstream transmission phase retarder is tunable by varying its incidence angle, and the downstream polarizer is tunable by translating a laterally grade...
متن کاملHigh-resolution soft X-ray photoelectron spectroscopy of liquid water.
High-resolution soft X-ray photoelectron spectra of liquid water (H(2)O and D(2)O) were measured using a liquid beam photoelectron spectrometer. The 1a(1) (O1s) band and the lowest valence 1b(1) band had single peaks, which is not consistent with the split 1b(1)→ 1a(1) of the X-ray emission band of liquid water if the splitting is assumed to originate from level shifts in two different hydrogen...
