Detection of TeV electrons as an evidence of the acceleration in nearby sources and a future project Original Research Article

The TeV electrons observed in the solar system are considered to be produced in the sources within 1 kpc in distance and in period for the past 100,000 years. The supernova remnants as a candidate of the electron sources are, therefore, very limited in number as Monogem, Loop 1, Geminga and Vela. It is expected that the few sources cause a structural component in the energy spectrum and an anisotropy in the arrival directions. Our calculations show that the direct effects of these nearby sources can be detected by a yearly observation with a detector having a geometrical factor of 0.5 m2 sr. We will present a future plan proposed for the observation of TeV electrons at the Japanese Experiment Module (JEM) in ISS.
