  1. Welcome to IHEP

  2. Introduction of IHEP Yifang Wang

  3. Institute of High Energy Physics A comprehensive and largest fundamental research center in China for: • Particle physics • Astroparticle physics • Accelerator technologies and applications • Synchrotron radiation technologies and applications • Total Staff: ~ 1300 + ~400 PhD Students and postdocs • Total budget/year: ~ 120M $ Established at 1950, and became an independent institute at 1973 .

  4. Research Divisions • Experimental Physics：BESIII, Daya Bay, BELLE II, CMS, ATLAS… • Particle Astrophysics：cosmic-rays, astrophysics, neutrino physics, particle astrophysics… • Theory：nuclear & particle physics, field theory, cosmology… • Accelerator: BEPC, high power proton accelerator, free electron laser, … • Multi-discipline Research: Beijing Synchrotron Radiation Lab., Nuclear Analysis Lab., … • Computing and Network • Applications

  5. BEPCII 2. BEPCII: High Lumi. Double–ring Collider • Build new ring inside existing tunnel. Two half new rings and two half old rings cross at two IR’s, forming a double ring collider.
