| ABSTRACT: |
The Balloon-born Experiment with a Superconducting Spectrometer
(BESS), aiming to search for primodial antiparticles in the cosmic
radiation, successfully carried out the second scientific flight
over Antarctica in the solar minimum pediod, in December 2007 -
January 2008. The spectrometer worked properly and recorded
4.6 billion cosmic ray events (Polar-I x 5) at float altitude.
We will describe the BESS-Polar program and BESS-Polar instrument
especially for the improvements made for BESS Polar-II, and report
the overview of the flight and the detector performance. |
