CosmoALEPH is an experiment operated in conjunction with the ALEPH detector. The ALEPH experiment took data from 1989 until the year 2000 at the Large Electron Positron Collider (LEP) at CERN. It provides, among others, high resolution tracking and calorimetry. CosmoALEPH used this e + e − detector for cosmic ray studies. In addition, six scintillator telescopes were installed in the ALEPH pit and the LEP tunnel. The whole experiment operated underground at a vertical depth of 320 meter water equivalent. Data from ALEPH and the scintillator telescopes provide informaton on the lateral distribution of energetic cosmic ray muons in extensive air showers. The decoherence curve of these remnant air shower muons is sensitive to the chemical composition of primary cosmic rays and to the interaction characteristics of energetic hadrons in the atmosphere. An attempt is made to extract the various interdependencies in describing the propagation of primary and secondary cosmic rays through the atmosphere and the rock overburden, and comparing the data with results from Monte Carlo (MC) calculations. Results on the multiplicity distributions of remnant air shower muons in ALEPH are also compared with expectations based on MC simulations. Data on the cosmic ray muon spectrum and charge ratio up to momenta of 3 TeV/c as obtained with the time projection chamber in ALEPH's strong magnetic field are presented. The large number of events also allowed to unambiguously observe muon tridents and to estimate the cross section for this process.

“…At this stage, both, the background from atmospheric neutrinos and the background from cosmic ray muons amount to roughly 10 5 events atmospheric neutrino induced muon events is based on [21]) , including about 5000 events attributed to prompt decays of charmed mesons [18]. The application of an energy cut will quickly suppress remaining cosmic ray muon background.…”

IceCube is a large neutrino telescope of the next generation to be constructed in the Antarctic Ice Sheet near the South Pole. We present the conceptual design and the sensitivity of the IceCube detector to predicted fluxes of neutrinos, both atmospheric and extra-terrestrial. A complete simulation of the detector design has been used to study the detector's capability to search for neutrinos from sources such as active galaxies, and gamma-ray bursts.

“…For a cosmic neutrino flux of E 2 ν × dN ν /dE ν = 10 −7 GeV (cm 2 s sr) −1 , roughly the final sensitivity of AMANDA-II [46], more than 1000 signal events per year are predicted. At this stage, the background of 10 5 events, consists mostly of atmospheric neutrinos [53] and prompt muons from charm decay in the atmosphere [54].…”

“…For an optimized energy cut N ch > 227, a simulated source with spectrum E 2 ν ×dN ν /dE ν = 1×10 −7 GeV (cm 2 s sr) −1 , previously introduced, results in 74 signal events in one year of operation compared to a background of 8 atmospheric neutrinos. The background was calculated including prompt decays of charmed mesons which may contribute as much as 80% to the final atmospheric sample following reference [54]. After three years of operation an overall flux limit of…”

Abstract.We introduce neutrino astronomy starting from the observational fact that Nature accelerates protons and photons to energies in excess of 10 20 and 10 13 eV, respectively. Although the discovery of cosmic rays dates back a century, we do not know how and where they are accelerated. We review the observations as well as speculations about the sources. Among these gamma ray bursts and active galaxies represent well-motivated speculations because these are also the sources of the highest energy gamma rays, with emission observed up to 20 TeV, possibly higher.We discuss why cosmic accelerators are expected to be cosmic beam dumps producing neutrino beams associated with the highest energy cosmic rays. Cosmic ray sources may produce neutrinos from MeV to EeV energy by a variety of mechanisms. The important conclusion is that, independently of the specific blueprint of the source, it takes a kilometer-scale neutrino observatory to detect the neutrino beam associated with the highest energy cosmic rays and gamma rays. The technology for commissioning such instrument has been established by the AMANDA detector at the South Pole. We review its performance and, with several thousand neutrinos collected, its first scientific results.
