  Thanks to recent technological development, a new generation of cosmic ray
experiments have been developed with more sensitivity to study these particles
in the primary energy interval from 10 TeV to 1 PeV, such as HAWC. Due to its
design and high altitude, the HAWC gamma-ray and cosmic ray observatory can
provide a bridge between the data from direct and indirect cosmic ray
detectors. In 2017 the HAWC collaboration published its first result on the
total energy spectrum of cosmic rays, which covers the range from 10 to 500
TeV. This work updates the previous result by extending the energy interval of
the measured all-particle cosmic-ray energy spectrum up to 1 PeV. The energy
spectrum was obtained from the analysis of two years of HAWC's data using an
unfolding method. We employed the QGSJET-II-04 model for the energy calibration
and the spectrum reconstruction. The results confirm the presence of a knee
like feature at tens of TeV, as previously reported by the HAWC collaboration
in 2017.
