【Abstract】 The solar X-EUV imaging telescope is being developed for meeting the requirement of domestic space weather forecast. It will be used to monitor and predict the solar activities that affect the space weather. The observed materials will be dedicated to the space weather forecast. The main research purposes of this thesis are to develop the physical, technical and operational design related to the solar X-EUV imaging telescope. Parts of the critical techniques of system are tackled.The main research contents of the physical design include: presenting the domestic and international status of space weather and expanding on the need and the importance about the space weather forecast; sorting the disastrous space weather and discussing their effects and adapted prediction methods; analyzing the solar disturbing resources of space weather and the precursor or concomitant phenomena of solar eruption based on the newest observational results; probing into the radiation principle of solar short-wave ray and presenting the computing methods about solar continuum and line spectrum radiation; extrapolating physical methods of reconstructing the temperature and the emission measure of coronal plasma; argumenting the effective observing spectrum for space weather empirical forecast and space weather numerical forecast.The main research contents of the technical design include: analyzing the necessary parts of the solar X-EUV telescope and the method of imaging X and EUV ray; developing the optic, electronic and mechanical design of this instrument; computing solar X-EUV imaging telescope’s response to different temperature plasma, analyzing combination application of telescope filters for reconstructing the plasma paramaters and apprasing the telescope’s response to the solar activities.The main research contents of the operational design include: working out the in-orbit experiment scheme and optimizing the in-orbit control and observation scheme for solar X-EUV imaging telescope; analyzing the requirements to the mounting platform of telescope; implementing the rudimental mechanical, electronic, thermal interface design.The research about the critical technique includes: developing the radiation-hard CCD sensitive to the X and EUV ray; implementing the design of CCD driving clock and signal readout electronic using CPLD; implementing shutter design which can realizing 1ms - 10s exposing time.It is the first time to be brought out and designed that the solar X-EUV imaging telescope integrates the grazing mirror and the normal incidence mirror. This design can fully meet the applied requirements according to simulation. The solar X-EUV imaging telescope operates in the 0.4-10nm X-ray intervals and the 19.5nm EUV wavelength. And it can provide the high resolving solar disk imaging for its field of view of 45 arcmin and spatial resolution of 5 arcsec. The size of the telescope is 236mmx795mm. The pixel array of the CCD is 544x544. Theoretical analysis shows the solar X-EUV imaging telescope can observe the active region, flare, CME, EIT wave, "dimming", "sigmoid" and "CUSP" phenomena. Compared with the international similar instruments, this telescope is the most powerful and efficient for space weather forecast. The telescope will be aboard the geostationary satellites. It will greatly enhance the capability in domestic space weather forecast if the telescope operates successfully in orbit.更多还原
