Cosmic Ray Energetics and Mass: First Flight and Beyond

Le résumé fourni par la source

The Cosmic Ray Energetics And Mass instrument is configured with particle detectors to measure cosmic-ray composition from protons to iron nuclei over the energy range from ~1011 to ~1015 eV in a series of balloon flights. The goal is to observe cosmic-ray spectral features and/or abundance changes that might signify a limit to supernova acceleration. Particle charge (Z) measurements are made with a timing-based detector and a pixelated silicon matrix. Particle energy measurements are made with a transition radiation detector for Z> 3 and a sampling tungsten/scintillator calorimeter for Z ≥ 1. The first flight of the instrument took place in Antarctica December 2004 – January 2005. It flew for a record-setting 42 days. Preliminary results from the ongoing analysis are presented, and future plans are discussed.
