    07/04/2021, 10:00

    DMIce-17 comprises of two 8.5kg NaI(Tl) scintillator crystals located beneath the IceCube array. We demonstrate that it is possible to distinguish muons detected in DMIce-17 from background, and then use this to determine the coincidence rate between high energy tracks measured in IceCube and said muons for data covering 2012-2020. Finally, we discuss how this may be used to improve the track...

    Mr Jordan Hanson (Whittier College)
    08/04/2021, 09:04

    Calibration of the IceCube-Gen2 radio array requires calibrations of the RF channels of stations, and constraining effects from the ice surrounding the channels. Regarding RF channel calibration, experience with ARA and ARIANNA has demonstrated the utility of fixed heartbeat calibration pulse units that probe RF channel response from a fixed location over time. Heartbeat units are operated...

    Mr Hanson Jordan (Whittier College)
    08/04/2021, 09:16

    The radio array design of IceCube-Gen2 relies on an understanding of the propagation of Askaryan radiation from UHE neutrino signals through the South Pole firn. Classical ray-tracing techniques are implemented in our standard Monte Carlo package, NuRadioMC, to solve the problem of arrival angle and location of surface signals that have curved paths through a changing index of refraction. ...

  17. 24. Advanced Propagation: Greenland FDTD Case Study and the Potential for Parabolic Equation Modeling [Time: 8+4]
    Cosmin Deaconu (University of Chicago)
    08/04/2021, 09:24

    This talk covers two topics related to "advanced" radio propagation (i.e. not raytracing). The first describes the use of finite-difference time-domain (FDTD) modeling to describe a radio dataset from Greenland and the second describes the potential application of parabolic equation (PE) modeling for in-ice studies. Unlike FDTD, PE is tractable over larger scales, but still leaves much to be...
