Topical Workshop on the CEPC Calorimetry

11 Mar 2019, 08:00 → 14 Mar 2019, 12:45 Asia/Shanghai

A415 (Institute of High Energy Physics, Beijing)

The Topical Workshop on the CEPC Calorimetry will take place during March 11-14, 2019 at the Institute of High Energy Physics (IHEP) in Beijing. It will be semi-informal with presentations interleaved with plenty of time for discussions.

This workshop intends to bring together experts on calorimetry to have informal and in-depth discussions on the technical options for the calorimeter system at the proposed circular electron positron collider (CEPC), including both the options presented in the Conceptual Design Report and possible new options.

Topics to be discussed include physics drivers, expected performance, channel count and data rate, power consumption, cost estimation as well as potential interested groups.

Meeting Room: A415, Main Building in IHEP
