Abstract
The Solar Isotope Spectrometer (SIS) aboard the Advanced Composition Explorer (ACE) has been
measuring solar energetic particle abundances since ACE was launched in August 1997. SIS is a silicon
detector telescope that identifies charged particles via the multiple dE/dx vs. total energy technique, and to
date, most measurements reported by SIS have been limited in energy to those particles that stop in the
instrument. In this paper, we will summarize the multiple dE/dx technique used to identify particles that
penetrate through the bottom of SIS, extending the energy ranges for elemental abundance measurements.
In preliminary analysis, the upper energy limit for oxygen has been extended from ~90 MeV/nuc for
stopping particles to ~300 MeV/nuc for penetrating particles, and the upper energy limit for iron has been
extended from ~168 MeV/nuc to ~500 MeV/nuc. We apply this technique to SIS measurements of large SEP
events, such as the Nov. 6, 1997 event and the recent Jan. 20, 2005 event, to extend the measured spectra, to
look for evidence of spectral breaks.
