Recent Results from the AMANDA Experiment

AMANDA (Antarctic Muon And Neutrino Detector Array) is a neutrino telescope built under the southern polar icecap and its scope is to explore the possibility to detect high energy cosmic neutrinos. This should generate insight into the powerful celestial objects where acceleration mechanisms can bring up to $10^{20}$ eV. We describe the achievements and results from the AMANDA-B10 prototype and the preliminary results from the current AMANDA-II detector which show dramatic increase in sensitivity.

Computational Techniques for Simulating Light Propagation in High-Energy Neutrino Telescopes

To maximize the accuracy of background simulation and event reconstruction, high-energy neutrino telescopes require detailed knowledge of light propagation over a large volume of detection medium. If light scattering and absorption leng ths in the medium are of the same scale as the detector size, this problem can only be handled numerically. Any inhomogeneity of optical properties in the medium further complicates the problem, requiring large computational resources. We present a treatment based on combining ray-tracing Monte Carlo and neural network techniques which offers a reasonable compromise between solution accuracy, computer memory and CPU usage.
