  AMS-02 is a cosmic ray experiment that will be placed on the International
Space Station. One of its goals is to search for WIMP Dark Matter, specifically
from anomalous features in the positron spectrum. In order to identify
positrons at high energy from the large background of protons, a Transition
Radiation Detector (TRD) will be used. Here we will present studies of
positron/proton separation using the TRD from the AMS-02 Simulation.
