Dual-readout calorimetry is now a mature and well-known technology which guarantees excellent electromagnetic and hadronic resolution in the same detector. It has recently being proposed in the framework of IDEA (Innovative Detector for Electron–Positron Accelerators) for both Future Circular Collider (FCC-ee) and Circular Electron–Positron Collider (CEPC). After being extensively tested on prototypes, the dual-readout calorimetry is now moving toward a technology design study in order to be realistically available for an experiment. In this context, a full simulation of the calorimeter has been developed and used to estimate the expected performance of the detector. At the same time, the development of a novel technique for mass production of the detector modules, at an effective cost, is ongoing. As a first step, an electromagnetic-size prototype is under construction for a testbeam data taking originally foreseen in November 2020 and now moved to spring 2021, due to the Covid-19 pandemic spread.

双读数量热法：现状和前景

双读出量热法现在是一项成熟且众所周知的技术，可确保在同一检测器中具有出色的电磁和强子分辨率。它最近在未来圆形对撞机 (FCC-ee) 和圆形电子-正电子对撞机 (CEPC) 的 IDEA（正负电子加速器创新探测器）框架中提出。在原型上进行了广泛测试后，双读出量热仪现在正朝着技术设计研究方向发展，以便实际可用于实验。在这种情况下，已经开发了热量计的完整模拟，并用于估计探测器的预期性能。同时，正在开发一种以有效成本大规模生产探测器模块的新技术。作为第一步，
