A design concept for a future ground-based cosmic-ray observatory using the Direct
Cerenkov technique will be presented. This technique can provide high precision,
largely model-independent, measurements of the energy and charge of heavy cosmic-ray
primaries in the region of the knee. It does so by exploiting the direct component
of Cerenkov radiation emitted by these primaries prior to thei

The Cosmic Ray Energetics and Mass (CREAM) balloon experiment had two successful
flights in 2004/05 and 2005/06. It was designed to perform energy measurements from
a few GeV up to 1000 TeV, taking advantage of different detection techniques. The
first instrument, CREAM-I, combined a transition radiation detector (equipped with an
array of proportional tubes and an acrylic Cherenkov device) w

Although SNRs are theoretically considered to be the most plausible candidates for
the acceleration of cosmic-ray hadrons up to PeV energies, no observations have
succeeded in definitely specifying those objects so far.
Since accelerated electrons have difficulty producing very high-energy gamma rays
with energies above 100 TeV via bremsstrahlung or inverse Compton scattering, it can
be an ef

The Track Imaging Cerenkov Experiment (TrICE) is an air Cerenkov telescope designed
to use a high resolution method for measuring cosmic-ray composition at TeV-PeV
energies. The method aims to separate the fast and compact direct Cerenkov signal
produced by primary cosmic ray nuclei in the upper atmosphere from the light produced
by the subsequent air shower cascade. Efficient discrimination

We present here the capabilities of the GLAST Large Area Telescope to detect cosmic
ray high-energy (HE) electrons in the energy range from 10 GeV to 1 TeV. We also
discuss the science topics that can be investigated with HE electron data and
quantify the results with LAT instrument simulations. The science topics include CR
propagation, calibration of the IC gamma-ray model, testing hypothese

Polarized gamma-rays are expected from a wide variety of sources including
rotation-powered pulsars, accreting black holes and neutron stars, and jet-
dominated active galaxies. Polarization measurements provide a powerful
probe of the gamma-ray emission mechanism and the distribution of magnetic
and radiation fields around the source. No measurements have been performed
in the soft gamma

Ground-based composition measurements of high-energy cosmic rays can be significantly
improved by using the direct Cerenkov method. This technique targets the Cerenkov
light produced by the primary particle prior to its production of an extensive air
shower. With the appropriate time and angular resolution, the direct Cerenkov
photons can be separated from those produced in the extensive air
