SUMMARY:Radar Detection of HE Neutrinos in the Ice\, Faculty Candidate
  Seminar\, Kael Hanson\, Université Libre de Bruxelles
DESCRIPTION:The recent IceCube measurement of an excess of neutrino ev
 ents in the energy range of 30 TeV to 2 PeV is an extremely interestin
 g result which points to the existence of a detectible neutrino signal
  from diffuse galactic and extragalactic cosmic ray acceleration sites
 .  The limited data is most compatible with a power law flux with spec
 tral index near -2\, consistent with production via Fermi shock accele
 ration\, however the limited dynamic range of the measurement renders 
 a large error in the determination of the behavior of the energy spect
 rum and future accumulation of statistics in IceCube above a PeV will 
 come slowly.  Extensions to the IceCube optical detector array are bei
 ng designed to increase the effective area by an order of magnitude.  
 Antenna arrays for the detection of extremely high energy neutrinos by
  their radio emission are also being designed and built\, however thes
 e facilities would not detect a significant number of neutrinos of thi
 s origin but are rather targeted toward the much higher energy cosmoge
 nic neutrino fluxes.  This presentation will explore the possibility o
 f detection of PeV scale energy and higher neutrinos using bistatic ra
 dars which reflect off of plasmas created in the energetic  electromag
 netic neutrino-induced cascades in the ice.
