Characterization of an IceTop tank for the IceCube surface extension IceVeto — •Julian Kemp, Jan Auffenberg, Bengt Hansmann, Martin Rongen, Martin Stahlberg, and Christopher Wiebusch for the IceCube collaboration — III. Physikalisches Institut B, RWTH Aachen University

IceTop is an air-shower detector located at the South Pole on the surface above the IceCube detector. It consists of 81 detector stations with two Cherenkov tanks each. The tanks are filled with clear ice and instrumented with two photomultipliers. IceTop detects cosmic-ray induced air-showers above an energy threshold of ∼300 TeV. Muons and neutrinos from these air-showers are the main background for astrophysical neutrino searches with IceCube. The usage of IceTop to veto air-showers largely reduces this background in the field of view.

To enlarge the field of view an extension of the surface detector, IceVeto, is planned. Therefore, we investigate the properties of an original IceTop tank as a laboratory reference for the development of new detection module designs. First results of these measurements are presented.
