Work Package 3 – Optical Calorimeters

Calorimeters based on scintillating materials and photodetectors have a long and successful history at high-energy particle colliders. Continuous technological progress in the field, from faster and more radiation-tolerant scintillators to compact and cheaper photodetectors such as Silicon PhotoMultipliers (SiPMs), has opened the possibility of novel calorimeter designs.
The goal of Work Package 3 is to explore, optimise and demonstrate with full shower-containment prototypes, new concepts of sampling and homogeneous calorimeters based on scintillating materials. A common trend among different calorimeter concepts is to improve the spatial granularity, the time and energy resolution and, in some cases, the radiation tolerance compared to state-of-the-art calorimeters. The calorimeter designs in this section do not plan to embed electronics and services inside the calorimeter but rather route the signal away from the active elements (while photodetectors are in some cases embedded). The vast majority of the proposed calorimeters exploit SiPMs as compact and cost-effective photodetectors insensitive to magnetic fields and envision the use of particle flow algorithms for event reconstruction.
