Measuring The Ne/O Ratio For Imap-Lo, Ryan J. Murphy

Honors Theses and Capstones

This paper aims to study if the thinner carbon foils of IMAP-Lo will lead to a better resolution of the C/O ratio and by extension, the Ne/O ratio. This is done by fitting an asymmetric kappa function to the time of flight spectra of both types of carbon foils. The ETU used in the most recent round of IMAP-Lo testing is outfitted with both 2ug/cm^2 and 1ug/cm^2 foils letting us create a model relating how the spectra change in response to different foil thickness. Using this model and validating it against test results, we simulate what we would expect to …
