| Abstract: | The Surface Enhancement of the IceTop air-shower array will include the
addition of radio antennas and scintillator panels, co-located with the
existing ice-Cherenkov tanks and covering an area of about 1 km$^2$. Together,
these will increase the sensitivity of the IceCube Neutrino Observatory to the
electromagnetic and muonic components of cosmic-ray-induced air showers at the
South Pole. The inclusion of the radio technique necessitates an expanded set
of simulation and analysis tools to explore the radio-frequency emission from
air showers in the 70 MHz to 350 MHz band. In this paper we describe the
software modules that have been developed to work with time- and
frequency-domain information within IceCube’s existing software framework,
IceTray, which is used by the entire IceCube collaboration. The software
includes a method by which air-shower simulation, generated using CoREAS, can
be reused via waveform interpolation, thus overcoming a significant
computational hurdle in the field. |
