摘要

Seven years of construction on the IceTop air shower array have culminated in the final detector setupof 162 ice-filled tanks. The tanks are paired as stations over an area of one square kilometer. A continuous andautomatic procedure calibrates each tank via the extraction of the vertical equivalent muon peak in the tank chargespectrum. Over the years snow has drifted unevenly on top of the tanks. The overburden of snow influences thecharge spectrum as the electromagnetic part of an air shower is attenuated more than the muonic part. The impact onindividual tanks affects trigger rates and the air shower event structure. We will present tank response studies with MonteCarlo simulations and compare them to measured IceTop charge spectra in light of the varying thickness of the snow layer.
