|Title||Measuring the Solar Wind Charge Exchange Emissivity in the Magnetosheath|
|Author||Dr Kip Dee Kuntz|
|Description||The Solar Wind Charge Exchange (SWCX) X-ray emission in the XMM band cannot be calculated from first principles due mostly to the lack of measured cross-sections (sigma_i) for many ion species. We propose to use the EPIC detectors to measure the SWCX emission where it is brightest, the sub-solar region of Earth.s magnetosheath (its nose). We will measure the effective cross-sections for 0.1 keV wide bands containing many blended lines from 0.35 keV to 0.7 keV as well as confirm laboratory-derived sigma_i for the strong O lines. Although the SWCX is interesting in itself, these measurements are essential for removing SWCX contamination from studies of the Galactic halo, the faint diffuse ISM, and the Local Hot Bubble (LHB).|

|Mission Description||The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
