Description
Noble liquid electromagnetic calorimetry is a strong candidate for high-precision detectors at future lepton colliders, including Higgs factories, due to its excellent energy resolution, response uniformity, and potential for fine spatial segmentation.
Within the Detector R&D Collaboration for Calorimeters (DRDCalo), key elements of a noble liquid calorimeter are being developed, addressing both readout and mechanical design. High-granularity readout is achieved using straight, multilayer electrode structures. Laboratory measurements with PCB prototypes demonstrate the feasibility of this readout concept and show good agreement with detailed simulations, supporting its compatibility with modern reconstruction techniques, including particle-flow algorithms and machine-learning-based approaches.
Mechanical R&D focuses on the design of absorber plates, support structures, and spacers. Laboratory tests with absorber prototypes provide input for simulation studies, while detailed simulations are performed to assess mechanical stability and guide design choices. These studies inform the overall detector layout and preparations for a future beam-test prototype.
This technology is being adopted in the ALLEGRO detector concept for FCC-ee, where noble liquid electromagnetic calorimetry is foreseen for both the barrel and endcap regions. Its integration within the key4hep software framework and expected performance are presented.
