“…3. See Seo et al (2004) for the instrument details. Multiple charge measurements with the TCD, CD, SCD, and S0/S1 layers of scintillating fibers accurately identify the incident particles by minimizing the effect of backscattered particles from the calorimeter.…”

“…The Cosmic-Ray Energetics And Mass (CREAM) experiment (Seo et al, 2004) was designed and constructed to measure cosmic-ray elemental spectra using a series of ultra long duration balloon (ULDB) flights. The goal is to extend direct measurements of cosmic-ray composition to the energies capable of generating gigantic air showers which have mainly been observed on the ground, thereby providing calibration for indirect measurements.…”

“…One of the main physics goals driving the CREAM investigation (Seo et al, 2004) is the experimental test of the validity of models based on cosmic ray (CR) acceleration by supernova shock waves. In a class of such models, a rigidity dependent critical energy is derived, which marks the limit where diffusive shock acceleration becomes inefficient.…”

“…In this way, the refurbishment operations that follow the recovery of one payload could take place almost simultaneously with the flight preparation of the second payload. The CREAM-1 instrument, flown for the first time in December 2004 with a conventional zero-pressure balloon, achieved a recordbreaking flight duration of 42 days (Seo, 2005). The second CREAM payload was launched from McMurdo in December 2005 and its flight lasted 28 days (Seo et al, 2006).…”

“…The balloon circumnavigated the Antarctic continent twice and floated at an altitude between 35 and 40 km with an atmospheric overburden of 3-4 g/cm 2 . The CREAM-1 instrument (Seo et al, 2004) included a sampling tungsten/ scintillating fiber calorimeter preceded by a graphite target with scintillating fiber hodoscopes, a pixelated silicon charge detector (SCD), a transition radiation detector (TRD) and a segmented timing-based particle-charge detector (TCD). The CREAM-2 instrument configuration did not include the TRD and scintillating fiber hodoscopes as in the first flight, while the charge identification performances of SCD were enhanced by the addition of a second layer of pixelated silicon sensors.…”

A review is given of the main properties of the charged component of galactic cosmic rays, particles detected at Earth with an energy spanning from tens of MeV up to about 10 19 eV. After a short introduction to the topic and an historical overview, the properties of cosmic rays are discussed with respect to different energy ranges. The origin and the propagation of nuclei in the Galaxy are dealt with from a theoretical point of view. The mechanisms leading to the acceleration of nuclei by supernova remnants and to their subsequent diffusion through the inhomogeneities of the galactic magnetic field are discussed and some clue is given on the predictions and observations of fluxes of antimatter, both from astrophysical sources and from dark matter annihilation in the galactic halo. The experimental techniques and instrumentations employed for the detection of cosmic rays at Earth are described. Direct methods are viable up to 10 14 eV, by means of experiments flown on balloons or satellites, while above that energy, due to their very low flux, cosmic rays can be studied only indirectly by exploiting the particle cascades they produce in the atmosphere. The possible physical interpretation of the peculiar features observed in the energy spectrum of galactic cosmic rays, and in particular the so-called "knee" at about 4×10 15 eV, are discussed. A section is devoted to the region between about 10 18 and 10 19 eV, which is believed to host the transition between galactic and extragalactic cosmic rays. The conclusion gives some perspectives on the cosmic ray astrophysics field. Thanks to a wealth of different experiments, this research area is living a very flourishing era. The activity is exciting both from the theoretical and the instrumental sides, and its interconnection with astronomy, astrophysics and particle physics experiences non-stop growth.
