IceCube is the world’s largest neutrino telescope, and it is still in the early stages of construction. In the last 19 months 604 Digital Optical Modules (DOMs) have been deployed, roughly 10% of the planned total. They comprise 540 modules on 9 strings located between 1.5km and 2.5km in the deep ice beneath the South Pole surface, and 64 modules located in a 16‐station surface air shower array called IceTop. IceCube’s instrumented volume will eventually reach 1 km3 in the ice and an area of 1 km2 on the surface.Each DOM is an independently running detector looking for Cherenkov radiation from charged particles which are produced when neutrinos interact near or in the detector. The deep ice under the South Pole is an excellent calorimetric medium and makes it possible for the array of modules to not only determine the direction of the neutrinos, but to measure their energies as well.The operation of the DOMs will be discussed, and results will be shown.
