The 2019 International Workshop on the High Energy Circular Electron Positron Collider

18 Nov 2019, 08:00 → 20 Nov 2019, 18:55 Asia/Shanghai

IHEP

Jianchun Wang (IHEP)

The 2019 international workshop on the high energy Circular Electron-Positron Collider (CEPC) will take place between November 18-20, 2019 at IHEP in Beijing.

The workshop intends to gather scientists around the world to study the physics potentials of the CEPC, pursue international collaborations for accelerator and detector optimization, deepen R&D work of critical technologies, and develop initial plans towards Technical Design Reports (TDR). The high energy Super proton-proton Collider (SppC), a possible upgrade of the CEPC, will also be discussed. Furthermore, industrial partnership for technology R&Ds and industrialization preparation of CEPC-SppC will be explored.

The workshop booklet can be accessed via https://indico.ihep.ac.cn/event/9960/page/8. In the booklet you may find the local maps useful to guide you around.
