| Abstract : | The whole heliosphere is permeated by the solar wind, a supersonic plasma flow of the solar origin which continuously expands into the heliosphere. During the last few decades, existence of two types of solar wind has caught the attention of the researchers. One is slow solar wind (speed ~400 km/s) and the other is fast solar wind (speed ~ 700 km/s). Another important aspect of the solar wind is the supra-thermal ion tail, which is not well understood yet. This tail is manifested in the form of particles in the energy range of a few KeV/n to several hundreds of KeV/n. In addition to the supra-thermal ions, there are energetic ions having energy range exceeding 1 MeV/n which are termed as solar energetic particles. Multi directional and continuous in situ measurements are required to investigate the angular distribution, temperature anisotropy of solar wind ions and origin of supra-thermal and energetic ions over an energy range spanning 100 eV – 5 MeV/n. In this
context, Aditya Solar wind Particle Experiment (ASPEX) payload on board Aditya L1 spacecraft is important.
ASPEX has two sub-payloads named as Solar Wind Ion Spectrometer (SWIS) and Supra Thermal and Energetic Particle Spectrometer (STEPS). SWIS measures the solar wind ion fluxes in the energy range of 100 eV – 20 KeV and STEPS measures Supra-thermal and energetic ion fluxes in the energy range of 20 KeV/n – 5 MeV/n. In this talk, salient features of ASPEX will be discussed along with the potential science issues. |
