“…The resulting code RadioPropa [73] solves the Eikonal equation in a local paraxial approximation thus enabling casting of rays through materials with arbitrary varying refractive index as may be required here. In addition, RadioPropa handles effects from boundary traversals such as reflection or partial reflection and allows for the implementation of propagating components of the electric field differently, such as needed for birefringence.…”

NuRadioMC is a Monte Carlo framework designed to simulate ultra-high energy neutrino detectors that rely on the radio detection method. This method exploits the radio emission generated in the electromagnetic component of a particle shower following a neutrino interaction. NuRadioMC simulates everything from the neutrino interaction in a medium, the subsequent Askaryan radio emission, the propagation of the radio signal to the detector and finally the detector response. NuRadioMC is designed as a modern, modular Python-based framework, combining flexibility in detector design with user-friendliness. It includes a stateof-the-art event generator, an improved modelling of the radio emission, a revisited approach to signal propagation and increased flexibility and precision in the detector simulation. This paper focuses on the implemented physics processes and their implications for detector design. A variety of models and parameterizations for the radio emission of neutrino-induced showers are compared and reviewed. Comprehensive examples a are used to discuss the capabilities of the code and different aspects of instrumental design decisions.Keywords Neutrino astronomy · radio detection · simulation · signal processing · ice propagation · Askaryan · PACS 07.05.Kf · 95.85.Ry · 95.55.Vj · 95.85.Bh · 07.05.Tp

Reconstructing the neutrino energy for in-ice radio detectors

et al. 2022

Since summer 2021, the Radio Neutrino Observatory in Greenland (RNO-G) is searching for astrophysical neutrinos at energies $${>10}$$ > 10 PeV by detecting the radio emission from particle showers in the ice around Summit Station, Greenland. We present an extensive simulation study that shows how RNO-G will be able to measure the energy of such particle cascades, which will in turn be used to estimate the energy of the incoming neutrino that caused them. The location of the neutrino interaction is determined using the differences in arrival times between channels and the electric field of the radio signal is reconstructed using a novel approach based on Information Field Theory. Based on these properties, the shower energy can be estimated. We show that this method can achieve an uncertainty of 13% on the logarithm of the shower energy after modest quality cuts and estimate how this can constrain the energy of the neutrino. The method presented in this paper is applicable to all similar radio neutrino detectors, such as the proposed radio array of IceCube-Gen2.

“…For the analysis presented in these proceeding, an analytic raytracing-solver is used, which calculates the raypath for a given start-and end-point only allowing to solve for exponential ice models. Other methods are currently being implemented in NuRadioMC, to support numerical raytracing [7] and a parabolic equations solver [8] to calculate the electric-field immediate at the antenna without the simplification of assuming ray optics.…”

The Radio Neutrino Observatory Greenland (RNO-G) is planned to be the first large-scale implementation of the in-ice radio detection technique. It targets astrophysical as well as cosmogenic neutrinos with energies above 10 PeV. The deep component of a single RNO-G station consists of three strings with antennas to capture horizontal as well as vertical polarization. This contribution shows a model-based approach to reconstruct the arrival direction of the neutrinos with an RNO-G station. The timing of the waveforms is used to reconstruct the vertex position. The shape and amplitude of the waveform are used to reconstruct the viewing angle. Together with the signal polarization it will add up to the neutrino arrival direction. We present the method used and the achieved angular resolution using the deep component of an RNO-G station.
