The bCALET-2 instrument for observing the electrons and the gamma rays at energies in 1-100 GeV, is composed of an imaging calorimeter, consisting of 4096 scintillating fibers with a total of 3.6 radiation lengths of tungsten plates, and a total absorption calorimeter, consisting of crossed 60 BGO logs of 13.4 radiation lengths depth. The bCALET-2 was launched from the Taiki Aerospace Research Field, Japan Aerospace Exploration Agency, in Hokkaido, and flew successfully for 2.5 hours at a level altitude of 35 km. In this paper, we will present the spectra of electrons and gamma rays in the energy range of 1-100 GeV measured by bCALET-2, compared with our previous observations, bCALET-1 and BETS. The detector performance is studied by comparing with the simulations, and the cosmic ray fluxes, which are compatible with previous experiments, are successfully obtained.","subitem_description_type":"Other"}]},"item_3_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態:
