Neural Network Analysis Tight and composition independent energy resolution Interpretation of NN mass output as linear combination of “pure” elements (p, He/O, Fe) → elemental fractions Calculation of by: E = 1-10 PeV log 10 (E/GeV) = 6.6-6.8 Toy Simulation p+Fe only! NN Output: Type 28
Summary 90% of IceCube are installed and running (completion in 2011). IceTop and IceCube offer various complementary possibilities for determining the cosmic ray energy spectrum and composition in the energy range between 1 PeV and 1 EeV. Requiring consistent results between all analyses will reduce systematic uncertainties and can be used for testing hadronic interaction models. First results are coming soon ... 29
