Studying X-ray Binary Systems
Studying roentgenogram Binary Systems1.0 Mission overview (0.5 pages max.)In response to the recent XMM Mission, relating to a explosive charge of studying X-ray binary systems, The XMM-Newton accusation helped scientists in solving a numerous cosmic mysteries, starting from the enigmatic black holes to the details about the origins of the Universe. Observation time on XMM-Newton is provided to the scientific community, which is applying for observatory periods. The proposed area details provide an order of magnitude lower particle background than those of other missions like Chandra and XMM-Newton, which would allow the detailed study and digest of low-surface-brightness diffuse objects.This proposed mission will be advancement on previous studies by the improvement in capabilities with response to scientific developments of the last few years and would match headspring with the goals set out in the recent call for ideas on x-ray observations. It flowerpot be also possible to increase the focal length of utilize micropore optics, which improves the high-energy response curve, hence this mission would thus be very highly significant in scientific and technological steps beyond Chandra/XMM-Newton and would take to heart important and timely inputs for the next upcoming generation of huge X-ray observatories like XEUS and Con-X planned for the upcoming years 2015-2025 horizons. This proposed next generation mission focuses on see restoration technique as well as ultra high photon imaging development the concepts of morphological Image processing and enhancing image quality. exclusively software and electronic hardware scientific research like VLSI design, SoC design are taken care in digital signal processing of the Image.The proposed mission is called N-XMM Mission (Next Generation XMM Mission). That comprises solutions for next generation imaging devices.1.1 InstrumentsEuropean Ultra high Photon imaging Camera (EUPIC) The MOS CCDs, EEV type 22, hav e 600 x 600 pixels, each 40 microns square they are frame-transfer devices and front illuminated. One pixel covers 1.1 with Image restoration technique. This instrument would work upon the quality of image capturing (i.e. Ultra high quality) and initial Image RenderingReflection Grating Spectrometer (RGS) It contains 182 identical types of gratings. The gratings are supposed to be mounted at grazing incidence into the in-plane or classical configuration, where both the incident as well as diffracted X-rays lies in a plane that is perpendicular (900 angle) to the grating grooves. This instrument is helpful in spectrum sensing and processing of X-rays as well as determines the elemental composition of specimen that is to be analysedOptical Monitor (OM) The Optical/UV Monitor background is mounted on the mirror support platform alongside the X-ray mirror module devices. It can provide coverage from 170 650 nm of that central 17 arc hour square region of the X-ray field, thus permi tting routine multi-wavelength epitome and observations of Multi Mirror targets simultaneously in X-ray as well as UV/ visual bands of frequency. This instrument helps in sensing simultaneous bands of energy waves that can be used for further analysis and can be digitally processed using SoC electronic devices in between only.1.2 MirrorThe main mirror of the reach will be Deployable Mirror. This will allow the spectral instruments to achieve resolutions from 0.000005032 arcseconds to 0.005032 arcseconds in the optic region of the spectrum.1.3 cooling SystemThe cooling system on board will be Passive, to achieve a temperature of 470 Kelvin. The minimum operating temperature required by the instruments is 40 Kelvin.1.4 Comments? (max. 50 words) Cooling System is taken Passive because the satellite has a large number of 50 kg and passive cooling is best for mass of 50 kg of for EUPIC, RGS and OM with a temperature of 470 Kelvin R = 1.22 (lambda/D) where, R is resolution, lambda is the wavelength and wavelength for x-rays are ranging from 0.01nm to 10nm and D=0.5m.2.0 Mass budgetThe total mass of the satellite will be 73 kg.

(max. 50 words)Now advancement is required in image restoration techniques, morphological kind of image processing techniques and SAS analysis of DATA. In all these fields new softwares can be made and used for clearer details.4.0 Technical Scientific JustificationX-ray physical science astronomy in space depends on the focusing of X-ray photons by low-angle scattering from fine shaped shells. In most of the cases this kind of optics contains two sets of nested homocentric shells with their shapes identical and similar to sections of different cones. Two grazing-incidence scatters would result in focusing of the X-rays on the shell axis. The previous ESAs XMM-Newton missi on had three mirror modules with outer diameter 70 cm, that too each having 58 nested shells that would be focusing on the X-rays onto CCD detectors some distance of 7m from the mirrors. XMM is in a highly eccentric orbit having closing distance 114000km, perigee distance 7000km and inclination angle 39. In this highly eccentric orbit, it is exposed to fluxes of electrons and ions of various high energies from Magnetospheric and Heliospheric sources.Big Data sets used for the analysis of different mission-critical engineering problems were produced by various scientific missions (IMP, SOHO, ACE, Equator-S, ISEE) which would never anticipate such applicationsN-XMM has its own on-board radiation monitor similar to that we had in X-NMM, to which there can be an early resistance in the project preparation. It would be an important resource on the spacecraftSpacecraft operators would have a keen provoke in the state of the space weather and hence would certainly use the predictions of particle enhancements.N-XMM wouldinclude the following types of science instrumentEuropean Ultra high Photon Imaging Camera (EUPIC) 3 CCD cameras are used for X-ray imaging, high resolution spectroscopy, and X-ray photometry XMM-Newtoncarries 2 MOS cameras and one pn. The gratings change the direction of about half of the squash incident flux to the RGS detectors so that about approx. 44% of the original incoming flux sets to the MOS (Motor only sync) cameras. The EUPIC instrument at the focus point of the third X-ray telescope with an highly energised unobstructed beam uses pn CCDs and hence is directed to as the pn camera. The EUPIC cameras perform task of extremely sensitive imaging analysis over the telescopes field of view (FOV) of 25 arcmin and in the energy ranging from 0.11 to 24 keV with flairrate spectral density (E/E 20-50). All EUPIC CCDs operates in photon counting mode with a fixed frequency and mode dependent frame read-out frequencyReflection Grating Spectrometer (RGS) Contains two very identical spectrometers for the purpose of high-resolution X-ray spectroscopy as well as spectro-photometry.Optical Monitor (OM) Used for optical imaging, UV imaging and grism spectroscopyComparisonXMM-Newton6150.15 154650b40Chandra0.20.50.1 1080050N-XMM3.570.1 244001.34.1 Figures/Diagrams/Tables for Technical Scientific JustificationFigure.1 Payload DesignFigure.2 Mechanical Design of XMM-OM TelescopeFigure.3 Schematic view of available orbits.Figure.4 Images Taken by LASCO and EITFigure.5 Optical Design of RGSTransmitterfrequency range2200 .. 2290 MHzAntenna output transmitting might+36 dBm (+2 dBm / 0 dBm)Transmitter modulationBPSK 4 MbpsPower consumption30 WReceiverFrequency range2025 .. 2110 MHzFrequency2058 MHzholding range100kHzError bit rateLess than10-6105 dBmReceiver demodulationBPSK 256 kbpsPower consumption3 WReceiver predisposition-105 dBm min error bit rate = 10-6AntennaPolarizationcircular/ RHCCoveringHemisphericalPowermax. 40dB m CWImpedance50-Operational temperature-40 +120CUplink frequency range2025 2110 MHzDownlink frequency range22002290 MHz
