Thurs AM II - In-Ice Neutrino Detail
Interferometric techniques are widely applied for a variety of radio detectors ranging from cosmology (redshifted 21 cm line and cosmic microwave background), radio astronomy (astrometry, imaging, and transient detection), and lightning. We present an interferometric technique for the reconstruction of ultra-wide band impulsive signals from ultra-high energy particles. This highly sensitive...

Thurs AM II - In-Ice Neutrino Detail
The Askaryan Radio Array (ARA) is one of the future neutrino observatories focusing on the detection of GZK-neutrinos with energies beyond 1017eV through secondary radio waves. Observing GZK-neutrinos is especially interesting because it is one of the few ways to investigate the CR-spectrum beyond the observed GZK-cutoff. These neutrinos, when reaching the earth, produce particle cascades in...

Thurs AM II - In-Ice Neutrino Detail
Coherent Cherenkov radio emissions from particle cascades were predicted by Askaryan, and the emissions were firstly detected at SLAC from the electro-magnetic cascades. Askaryan Radio Array (ARA) is being built at the South Pole to observe cosmogenic neutrinos by detecting the coherent radio emissions with the large instrumental area of about 100 km^2. We are planning an end to end...

Thurs AM II - In-Ice Neutrino Detail
Antarctic ice represents the interaction volume for multiple UHE neutrino experiments. When neutrinos collide with ice particles they produce radio waves that propagate to in-ice, surface, or balloon-borne detectors. The radio frequency signal strength observed at the detector, however, depends on the radio frequency attenuation length of the ice through which the neutrino-generated signal...

Information about thermal probes and how to use them for autonomous deep drilling in ice will be given. The method presented may be useful for drilling holes at large distances and/or large numbers, necessary for building big (hybrid) arrays for cosmogenic neutrino detection.
