“…The operation of the ARIANNA test bed at Moore's Bay, since its completion in November 2014, has provided a robust proof of concept for an in-situ, radio-based UHE neutrino detector. Iterative improvements in data acquisition and power systems since the first ARIANNA prototypes [15] and initial test bed stations [29] have improved reliability and livetime. We have presented the analysis of 4.5 years of data, leading to a 90% confidence upper limit on the diffuse neutrino flux of E 2 Φ = 1.3 × 10 −6 GeVcm −2 s −1 sr −1 for a decade wide logarithmic bin centered at a neutrino energy of 10 18 eV.…”

The primary mission of the ARIANNA ultra-high energy neutrino telescope is to uncover astrophysical sources of neutrinos with energies greater than 10 16 eV. A pilot array, consisting of seven ARIANNA stations located on the surface of the Ross Ice Shelf in Antarctica, was commissioned in November 2014. We report on the search for astrophysical neutrinos using data collected between November 2014 and February 2019. A straight-forward template matching analysis yielded no neutrino candidates, with a signal efficiency of 79%. We find a 90% confidence upper limit on the diffuse neutrino flux of E 2 Φ = 1.7 × 10 −6 GeVcm −2 s −1 sr −1 for a decade wide logarithmic bin centered at a neutrino energy of 10 18 eV, which is an order of magnitude improvement compared to the previous limit reported by the ARIANNA collaboration. The ARIANNA stations, including purpose built cosmic-ray stations at the Moore's Bay site and demonstrator stations at the South Pole, have operated reliably. Sustained operation at two distinct sites confirms that the flexible and adaptable architecture can be deployed in any deep ice, radio quiet environment. We show that the scientific capabilities, technical innovations, and logistical requirements of ARIANNA are sufficiently well understood to serve as the basis for large area radio-based neutrino telescope with a wide field-of-view.

“…The ARIANNA DAq mainboard is designed around the Synchronous Sampling plus Triggering (SST) chip [29,34,35]. Incoming signals are sampled at 2 GSa/s and held in a 256 sample circular buffer, which is read out when a triggering condition is met.…”

“…This is due to the smaller accuracy of the fits to the electromagnetic and hadronic vector potentials in Eqs. (14) and (15) in the time range outside the window (−0.5, 0.5) ns. An improved fit or an interpolation of the MC results instead of the fit is expected to increase the accuracy of our methodology even in the region where the amplitude of the vector potential is negligible compared to that at the peak.…”

“…Due to the smaller accuracy of the fits to the vector potentials given in Eqs. (14) and (15) in the time region outside the (−0.5, 0.5) ns window, the accuracy between the model and the full MC simulations drops to about 20% in the onset and in the latest times of the pulse. However, the amplitude also drops by at least three orders of magnitude in these regions and it is not expected to be relevant for practical purposes.…”

Askaryan radiation from neutrino-induced showers in ice

We present a semi-analytical method for the calculation of coherent Askaryan radiation in showers induced by neutrinos of any flavor in ice. We compare our results with those of a full Monte Carlo simulation based on the ZHAireS code. This approach is able to reproduce the vector potential and hence electric field at any experimentally relevant observer position in the time domain. This work extends published results only valid for electron-induced showers. We establish the validity of the semi-analytical calculation of the radio signal produced by all types of neutrino-induced showers in ice. The method is computationally efficient and only requires as inputs the longitudinal charge excess profile of the showers and a parameterization of the vector potential in the far-field region of the shower at the Cherenkov angle that we also provide. Our methodology avoids tracking the contributions to the electric field from millions of particles every time the radio pulse has to be calculated at a given observer position. These results can be readily used in the interpretation of the data taken by experiments, and in the planning and design of future initiatives based on the radio technique in ice.

Abstract. The origin of the highest energy cosmic rays at ∼10 20 eV is still unknown. Ultra-high energy neutrinos from the GZK process should provide information on the sources and their properties. A promising and cost effective method for observing GZKneutrinos is based on detection of Askaryan radio pulses with antennas installed in ice. The ARIANNA project aims at instrumenting a 36*36 km 2 large area on the Ross Ice Shelf with an array of radio detection stations. The deployment of a test system for ARIANNA, the Hexagonal Radio Array (HRA), was completed in December 2014. The three first stations were installed in 2012. Solar panels are used to drive the < 10 W stations. The system hibernated at sunset in April and all stations returned to operation in September. The site is essentially free of anthropogenic noise. Simple cuts eliminate background and provides for efficient selection of neutrino events. Prospects for the sensitivity of the full ARIANNA array to the flux of GZK neutrinos are shown.
