Comparison of Optical, Radio, and Acoustical Detectors for Ultrahigh-Energy Neutrinos

open access: yes, 1995
For electromagnetic cascades induced by electron-neutrinos in South Pole ice, the effective volume per detector element (phototube, radio antenna, or acoustic transducer) as a function of cascade energy is estimated, taking absorption and scattering into
