Observation of Ultra-high-energy Cosmic Rays with the ANITA Balloon-borne Radio Interferometer Locations of direct (black) and reflected (red) detection of ultrahigh energy cosmic ray events by the ANITA balloon experiment over Antarctica. The field of view is delineated by the dashed blue line. [S. Hoover et al., Phys. Rev. Lett. 105, 151101 (2010)] Physical Review … Read more →

New Limits on the Ultra-high Energy Cosmic Neutrino Flux from the ANITA Experiment

publication-icon

We report initial results of the first flight of the Antarctic Impulsive Transient Antenna (ANITA-1) 2006- 2007 Long Duration Balloon flight, which searched for evidence of a diffuse flux of cosmic neutrinos above energies of E_v ~= 3×10^18 eV. ANITA-1 flew for 35 days looking for radio impulses due to the Askaryan effect in neutrino-induced … Read more →

The Antarctic Impulsive Transient Antenna Ultra-high Energy Neutrino Detector Design, Performance, and Sensitivity for 2006-2007 Balloon Flight

publication-icon

We present a detailed report on the experimental details of the Antarctic Impulsive Transient Antenna (ANITA) long duration balloon payload, including the design philosophy and realization, physics simulations, performance of the instrument during its first Antarctic flight completed in January of 2007, and expectations for the limiting neutrino detection sensitivity. Neutrino physics results will be … Read more →

ANITA-I Antarctic Travel Log

November 1-15, 2006 The initial ANITA team arrived the first week of November, and the gondola build was in full swing by the 2nd week, and nearing completion at the end of that week. The major efforts have been focused on painting & silver -taping for thermal control, and starting the channel calibrations which will … Read more →
