Time Calibration
muon time calibration verification
Muon time calibration verification
  • reconstruct muon tracks without DOM X
  • plot the time residual for DOM X for nearby reconstructed tracks
  • if scattering length is longer than the distance cut (10 m) the most likely residual should be 0, otherwise residual will show delay increasing with the amount of scattering.
summary
Summary
  • The first IceCube string and four IceTop stations were deployed last austral summer; analysis began after freeze-in.
  • The ability to reconstruct muons and air showers, and to detect muons coincident with air showers was demonstrated
  • The observed muon flux is consistent with the expectation from the simulation
  • The overall detector timing uncertainty was measured to be below ~3 ns
  • The first elements of the IceCube detector perform as expected, or better.
  • Deployment of up to 10 IceCube strings and 20 IceTop tanks is scheduled for the coming season.
