Abstract
We present a measurement of the cosmic-ray spectrum between 7 GeV and 2 TeV performed with almost seven years of data collected with the Fermi Large Area Telescope. We find that the spectrum is well fit by a broken power law with a break energy at about 50 GeV. Above 50 GeV, the spectrum is well described by a single power law with a spectral index of . An exponential cutoff lower than 1.8 TeV is excluded at 95% CL.
