[40.12] Cosmic Ray Composition: Preparation for an Analysis of 2002 AMANDA Data

A. Heffner-Wong (Wichita State University), K. Rawlins (MIT)

Cosmic rays exist in a wide range of energies (109 to 1020 eV). Around 1015 eV, a “knee” appears in the cosmic ray energy spectrum where its slope steepens. The processes which create this steepening are unknown. The Antarctic Muon and Neutrino Detector Array (AMANDA), used primarily to detect neutrinos, can be used to study cosmic rays in the knee region. By studying the composition of these cosmic rays, we hope to gain insight into the mechanisms which create the steepening. This presentation will describe the process of studying cosmic ray composition with AMANDA as well as work I did on the initial stages of the analysis. This work was supported by a NSF-REU site grant (AST-0139563) to the University of Wisconsin - Madison.
