Method to improve the speedup of the IceTop simulations due to snow accumulation on tanks

Introduction

  • IceTop simulation challenge: Different snow coverage of tanks for each year.
  • My project: Test a method through which might be possible to improve the general speedup of the simulations.

Snow heights on top of IT tanks measured in Feb. 2012.

  • Snow height on top of the tanks increases on average by 20 cm every year.
    • Significant impact on the measured signal and systematic uncertainties.

Introduction

Snow accumulation over the IceTop detector, measured in three different years: 2010, 2011, and
2012.
