Future circular electron–positron colliders operating at s=90, 160, 240 and 350 GeV as Z, W, H and t factories will demand experiments with superior momentum and energy resolution for all the possible final-state particles produced. The IDEA Detector aims at satisfying these requests by exploiting an ultra-light drift chamber as the largest central tracker and a dual-readout fiber calorimeter for both electromagnetic and hadronic energy measurements. In this paper I review the dual-readout calorimeter baseline choices, as well as the related R&D work.
