We describe our laboratory procedures for precise measurements of lattice surface profile, where Bragg reflection takes place, of bent monocrystal wafers. A comparison of X-ray spectrometer characteristics for perfect and real crystals is presented. The described procedures will be used to measure the properties of the crystals that will be used as the dispersive elements in the future solar X-ray spectrometers SolpeX and ChemiX. 相似文献

Interhelioprobe (IHP), an analogue to the ESA Solar Orbiter, is the prospective Russian space solar observatory intended for in-situ and remote sensing investigations of the Sun and the inner heliosphere from a heliocentric orbit with the perihelion of about 60 solar radii. One of several instruments on board will be the Bragg crystal spectrometer ChemiX which will measure X-ray spectra from solar corona structures. Analysis of the spectra will allow the determination of the elemental composition of plasma in hot coronal sources like flares and active regions. ChemiX is under development at the Wroc?aw Solar Physics Division of the Polish Academy of Sciences Space Research Centre in collaboration with an international team (see the co-author list). This paper gives an overview of the ChemiX scientific goals and design preparatory to phase B of the instrument development. 相似文献
