离子和电子传感器(IES)是Rosetta等离子体联盟(RPC)的一部分。IES由两个静电等离子体分析器组成，每个分析器一个离子和一个电子，它们共享一个共同的入射孔径。每个分析仪的能量/电荷范围从1 eV/e到22keV/e，分辨率为4%。入射光口处采用静电偏转，获得90°×360°(2.8πsr)的视场。角分辨率为5°×22.5°(电子)和5°×45°(离子)，并将含有太阳风的扇区进一步分割为5°×5°。IES获得的三维等离子体分布将被用来研究太阳风与小行星Steins和Lutetia以及67P/Churyumov-Gerasimenko(CG)彗星的彗发和核的相互作用。此外，在这些天体上获得的光电子能谱将有助于确定它们的组成。
The ion and electron sensor (IES) is part of the Rosetta Plasma Consortium (RPC). The IES consists of two electrostatic plasma analyzers, one each for ions and electrons, which share a common entrance aperture. Each analyzer covers an energy/charge range from 1 eV/e to 22 keV/e with a resolution of 4%. Electrostatic deflection is used at the entrance aperture to achieve a field of view of 90°× 360° (2.8π sr). Angular resolution is 5°× 22.5° for electrons and 5°× 45° for ions with the sector containing the solar wind being further segmented to 5°× 5°. The three-dimensional plasma distributions obtained by IES will be used to investigate the interaction of the solar wind with asteroids Steins and Lutetia and the coma and nucleus of comet 67P/Churyumov–Gerasimenko (CG). In addition, photoelectron spectra obtained at these bodies will help determine their composition.
