  Shock heating and particle acceleration processes are some of the most
fundamental physical phenomena of plasma physics with countless applications in
laboratory physics, space physics, and astrophysics. This study is motivated by
previous observations of non-thermal heating of heavy ions in astrophysical
shocks (Korreck et al. 2004). Here, we focus on shocks driven by Interplanetary
Coronal Mass Ejections (ICMEs) which heat the solar wind and accelerate
particles. This study focuses specifically on the heating of heavy ions caused
by these shocks. Previous studies have focused only on the two dynamically
dominant species, H+ and He2+ . This study utilizes thermal properties measured
by the Solar Wind Ion Composition Spectrometer (SWICS) aboard the Advanced
Composition Explorer (ACE) spacecraft to examine heavy ion heating. This
instrument provides data for many heavy ions not previously available for
detailed study, such as Oxygen (O6+, O7+), Carbon (C5+, C6+), and Iron (Fe10+).
The ion heating is found to depend critically on the upstream plasma
