SUMMARY:High Energy Cosmic Rays with CREAM\, Fermi\, and Beyond\, NPAC
  (Nuclear/Particle/Astro/Cosmo) Forum\, Terri J. Brandt\, Ohio State U
 niversity
DESCRIPTION:The origins\, acceleration mechanism(s)\, and propagation 
 of high energy cosmic rays within the galaxy have been a mystery for n
 early 100 years. Today's experiments are beginning to provide a more c
 omplete and definitive answer to these classic questions. I will discu
 ss one such: the Cosmic Ray Energetics And Mass (CREAM) balloon-borne 
 experiment. CREAM uses a complementary set of charge\, energy\, and tr
 acking detectors on successive balloon flights around the Antarctic co
 ntinent to directly measure individual CR nuclei's spectra over 5 orde
 rs of magnitude in energy. These spectra provide clues to CR origins a
 nd acceleration mechanisms. To better understand CR propagation\, we h
 ave extended the Boron to Carbon ratio over an order of magnitude high
 er in energy than previous measurements. I will then explore a few way
 s ongoing and upcoming detections of CR signatures with gamma-ray and 
 neutrino detectors may shed further light on the classic CR questions\
 , both through direct and indirect detection.<br>
