Abstract
SMILE (Solar wind Magnetosphere Ionosphere Link Explorer) is a space
mission dedicated to study the interaction of the solar wind with the
Earth's magnetic field. SMILE will investigate the dynamic response of
the Earth's magnetosphere to the impact of the solar wind in a unique
manner, never attempted before: it will combine soft X-ray imaging of
the Earth's magnetic boundaries and magnetospheric cusps with
simultaneous UV imaging of the Northern aurora, while simultaneously
providing context measurements via an in situ plasma and magnetometer
instrument package. SMILE is a joint European Space Agency (ESA) and
Chinese Academy of Sciences (CAS) collaborative mission due for launch
in 2021. This talk will describe the Soft X-ray Imager (SXI) on SMILE.
The SXI is designed for good detection sensitivity of the soft X-rays
(0.2 - 2.0 keV) produced in the Earth's exosphere by the solar wind
charge exchange process. This process is the mechanism by which it is
possible to globally image the Earth's dayside magnetosheath,
magnetopause boundary, bowshock and cusps. The wide field of view of the
instrument (27° x 16°) is achieved by the use of a micropore
optic (MPO) with a Lobster-eye focusing geometry. The detector consists
of two large format CCDs (each 8.1 cm x 6.8 cm sensitive area) providing
high quantum efficiency and medium energy resolution for soft X-rays.
The instrument design will be presented along with simulation results
indicating the instrument sensitivity and science return.
