BESS
BESS is a particle physics experiment carried by a balloon. ''BESS'' stands for Balloon-borne Experiment with Superconducting Spectrometer. It is in fact a series of experiments that started in 1993, and its current incarnation, BESS-Polar, was circling the Antarctic from December 13 to December 21, 2004, for a total of 8 days 17 hours and 2 minutes. This joint Japanese and American project is supported by the Laboratory for High Energy Astrophysics (LHEA) at NASA's GSFC and the KEK. ==Overview== The mission of this experiment is to detect antiparticles in the cosmic radiation at high altitudes. It is therefore designed to be carried aloft by balloon. The central detection device is a magnetic spectrometer, that is used to identify all electrically charged particles crossing its main detection aperture. Mission members are working on improving the sensitivity and precision of this system with each new launch.
