Title: Simulation of RF Signals for Calibration in Neutrino Detection Experiments
Abstract: The discovery of the first potential extragalactic neutrino source marked an entry point in multi-messenger neutrino astronomy. The Radio Neutrino Observatory in Greenland (RNO-G) is designed to detect ultra-high energy neutrinos (UHEN) within the Greenland ice sheet. It provides a unique perspective of the Northern sky and serves to inform the design for the future radio component of the IceCube-Gen2 neutrino observatory in the South Pole. Given the large scale of future radio detector arrays, it's necessary to fully characterize any systematic differences in signal response across the array, as well as to measure radio frequency (RF) ice properties over the full range of possible UHEN signal geometries. The latter requires operation of in-ice calibration sources in dedicated transmitter holes.
The seminar talk will be dedicated to the concept design of proposed calibration tools and simulation of transmitted RF signals for borehole location optimization, as well as simulation of a possible background source - in ice volume scattering.
