Abstract
Here we present the methodology of extending TWINS composition analysis of oxygen and hydrogen to higher energies. Previous models for the start pulse height distributions for each TWINS sensor was developed from 1-50 keV for oxygen and hydrogen. Now, with new experimental data collected with the TWINS EM sensor, we have constructed a new model for the start pulse height distributions for hydrogen to the full energy range of the instrument 1-100 keV/amu and oxygen to 16 - 256 keV. On 17 March 2015 a major geomagnetic storm occurred (the minimum Dst is approximately ≤ -223 nT), where we present the first TWINS oxygen and hydrogen high-energy global ENA images.
