Description
The Antarctic Ross Ice Shelf Antenna Neutrino Array (ARIANNA) is an ultra-high energy neutrino detector currently under construction in Moore's Bay, in Western Antarctica. ARIANNA is designed to trigger upon and digitize GHz radio-frequency (RF) pulses created by neutrino interactions, via the Askaryan effect. In order to reconstruct the distinctive shape of this electric field, the time-domain response of both the deployed log-periodic radio antennas, and the RF amplifiers, must be quantified. Extensive, three-dimensional impulse response data was taken at the anechoic chamber at the University of Kansas, with the goal of understanding how the incident electric field is converted to a voltage waveform in the ARIANNA system. The first results for the antenna and amplifier response functions will be presented, along the primary direction of radiation of the antenna. Additionally, the angular dependence of the response function will be discussed.
