Description
IceTop, the surface component of the IceCube detector, has mea-
sured the energy spectrum of cosmic ray primaries in the range be-
tween 1.58 PeV and 1.26 EeV. This measurement was done by sam-
pling the lateral distribution function at distances from the shower axis
where the signal does not depend strongly on systematic variations in
the muon content of the air showers. Since May 2010, an improve-
ment in optical modules' readout enables the detection of muons at
large distances from the shower axis. Using this feature, and detailed
knowledge of the detector response, one can derive the average lateral
distribution function of low energy muons at large distances from the
shower axis. We will discuss how the resulting muon lateral distribu-
tion function compares with previous measurements and current air
shower simulations.
