The BETS (balloon-borne electron telescope with scintillating fiber) detector has been developed for high-altitude balloon flights to observe high-energy cosmic-electrons. The detector consists of an imaging calorimeter and a trigger system for particle identification and energy measurement. The calorimeter is composed of scintillating fibers and leads of a total thickness of {approx}8 r.l. Two sets of an image-intensifier and CCD camera system are adopted for read-out of 10,080 scintillating fibers. The accelerator tests were carried out to study performance of the detector by the CERN-SPS electron and proton beams. It is demonstrated in the flight data that a reliable identification of the electron component has been successfully achieved up to 100 GeV, and the energy spectrum has been measured.
