  1. CIC method applied to the KASCADE-Grande muon data Juan Carlos Arteaga-Velázquez for the KASCADE-Grande Collaboration Institute of Physics and Mathematics Universidad Michoacana CIC method applied to KG muon data – J.C. Arteaga Malargüe 2008, PAO Coll. Meeting

  2. The KASCADE-Grande experiment KASCADE-Grande (Karlsruhe Shower Core and array detector) E = 1016 - 1018 eV Grande detectors measure e/ +  component simultaneously KASCADE shielded scintillators allow to measure  component of EAS. (E > 230 MeV  sec) CIC method applied to KG muon data – J.C. Arteaga Malargüe 2008, PAO Coll. Meeting

  3. Reconstruction of N Measured  densities in KASCADE (r) = N  f(r) N =  n(ri) /  [f(ri)Aicos(z)] f(r) known from MC simulations N corrected from reconstruction systematics CIC method applied to KG muon data – J.C. Arteaga Malargüe 2008, PAO Coll. Meeting

  4. Muon spectra KG data Teff = 603.1 days CIC method applied to KG muon data – J.C. Arteaga Malargüe 2008, PAO Coll. Meeting

  5. Integral muon spectra Apply cut at constant Jcut For a given Jcut, get N() CIC method applied to KG muon data – J.C. Arteaga Malargüe 2008, PAO Coll. Meeting

  6. Muon attenuation curves Choose the mean Get attenuation curves CIC method applied to KG muon data – J.C. Arteaga Malargüe 2008, PAO Coll. Meeting

  7. Reference angle Find reference angle ref for normalization:  N24 of each event For the moment use only showers < 42o CIC method applied to KG muon data – J.C. Arteaga Malargüe 2008, PAO Coll. Meeting

  8. Muon spectra Good agreement between muon spectra for vertical showers CIC method applied to KG muon data – J.C. Arteaga Malargüe 2008, PAO Coll. Meeting

  9. Muon spectra Difference between MC and KG muon attenuation lengths FLUKA/QGSJET II CIC method applied to KG muon data – J.C. Arteaga Malargüe 2008, PAO Coll. Meeting

  11. Muon number systematic uncertainties CIC method applied to KG muon data – J.C. Arteaga Malargüe 2008, PAO Coll. Meeting

  12. Summary • Using the CIC method, we compared the muon spectra for different without the influence of MC models. • Good agreement among reconstructedmuon spectra from KG data on vertical showers with the CIC method. • Simulated Λ is different from the one obtained from the CIC method andthe KG data.
