Measuring 10-1000 GeV Cosmic Ray Electrons with GLAST/LAT

Understand

We present here the capabilities of the GLAST Large Area Telescope to detect cosmic ray high-energy (HE) electrons in the energy range from 10 GeV to 1 TeV.

• We also discuss the science topics that can be investigated with HE electron data and quantify the results with LAT instrument simulations.
• The science topics include CR propagation, calibration of the IC gamma-ray model, testing hypotheses regarding the origin of HE energy cosmic-ray electrons, searching for any signature of Kaluza Klein Dark Matter annihilation, and measuring the HE electron anisotropy.
• We expect to detect ~ 107 electrons above 20 GeV per year of LAT operation.
