Description
  • I3geant Simulation for Supernova Neutrinos
  • The same MC also simulates atmospheric muon events. Please click on the following link. Atmospheric Muons
  • Full Geant-3.21/GCALOR Simulation of the IceCube Detector. The AHA ice model was used.



Current Results for the Final IceCube Geometry (78 + 8). A SN temprature of T = 6.5 MeV is assumed. A total of 1,000,000 e+'s were simulated. These results use the latest DOM acceptance datafiles from Chiba. A 15% threshold for PE detection has been applied.

  • The SN neutrino energy distribution according to a Fermi function with T = 6.5 MeV (top),
  • and the positron energy distribution from the inverse beta decay reaction (bottom).
  • The flux-integrated cross section for the inverse beta decay reaction is 0.37 x 10^-40 cm^2

       
  • The fiducial volume peppered by 740,000 positrons.

       
  • Two-DOM fraction coincidence plots (left). Ratio of 2+ DOM hits to all hits is about 2%. Number of hits per DOM (right). Note, these plots are for the whole detector (5160 DOMs).

           
  • Two-DOM fraction coincidence plots (left). Ratio of 2+ DOM hits to all hits is about 5.6%. Number of hits per DOM (right). Note, these plots are for the DeepCore only.

           
  • DOM sensitivity range for IC-86 to C-light from the SN positrons (left) and DOM sensitivity range for DC to C-light from the SN positrons (right).

           

    Results for the Final IceCube Geometry (78 + 8). A SN temprature of T = 6.5 MeV is assumed. A total o:0 f 10,000,000 e+'s were simulated. These results use the old DOM acceptance datafiles

    • Hit distributions for single DOM hits

                 
    • Two-DOM fraction coincidence plots (left); Number of hits per DOM (right)

             
    • DOM Occupancy Plot for SN Positrons. Note the bottom of the detector has much clearer ice.

         

      Results for IceCube Geometry (80 + 6)

      • Hit distributions for single DOM hits

               
      • Two-DOM fraction coincidence plots

           
      • Hit distribution and the corresponding hit times in mu-sec.

               
      • An event display of a sample of e+ SN events. Note the scattering and absorption are taken from the AHA ice model.
