First Results from the IceTop Air Shower Array

IceTop is a 1 km^2 air shower detector presently under construction as a part of the IceCube Observatory at South Pole. It will consist of 80 detector stations, each equipped with two ice Cherenkov tanks, which cover 1 km^2. In 2008, the detector is half completed. One of the design goals of the det...
