Abstract:
Gamma ray source detection above 30 TeV is an encouraging approach for finding galactic cosmic ray sources. Wide field of view survey for gamma ray source population above 100 GeV is essential. In order to target those goals, a large air shower particle detector array of 1km2 (the LHAASO project) at 4300 m a.s.l. is proposed. With two MagicII-type telescopes, the project will be enhanced for source morphologic investigation. The proposed array will be utilized also for energy spectrum measurement for individual cosmic ray species from 30 TeV to 10 PeV. Re-configuring the wide field of view telescopes into fluorescence light detector array allows cosmic ray spectrum and composition measurements above 100 PeV where the second knee is located.
Coffee and tea will be served 20 minutes prior to the seminar.
