Measuring the low-energy electron and positron spectrum (20-300 MeV) with the AESOP-Lite balloon mission
Abstract
AESOP-Lite (Anti-Electron Sub-Orbital Payload) is a high-altitude balloon mission poised to launch from Esrange, Sweden in May 2018. It will measure the cosmic rays electron and positron fractions in the energy range of 20-300 MeV. The data will provide a calibrated reference at 1 AU to be compared with Voyager interstellar electron observations and extending the range of measurements made by PAMELA and AMS on the lower end of the spectrum. This novel measurement will be crucial in order to understand the origin and propagation of low-energy electrons in the heliosphere.I will present on the AESOP-Lite science goals, instrument design, and the status of its very first flight.
