Abstract

The aims of the BESS-Polar experiment are precise measurements of the low-energy antiproton spectrum and search for cosmologically significant antimatter. After its first flight (BESS-Polar I), we had developed a new spectrometer based on the feedback from the results. Most of the detector components had been redesigned and upgraded to improve their performance and to increase the data taking period and capacity. The second flight (BESS-Polar II) was successfully carried out in December 2007- January 2008. We performed 24.5 days scientific observation just at the solar minimum. In this paper, BESS-Polar II instrument and flight summary will be presented.
