About this Research Topic
Calorimeters are divided into two main categories, homogeneous and sampling. The best compromise between these two technologies is studied to optimize experimental requirements and minimize the drawbacks associated with the limitations of standard solutions. The most recent technological developments allow us to get rid of this rigid distinction in favor of novel architectures. The modern tracking systems provide very accurate reconstruction, so the jet performance in particle flow-like reconstruction algorithms is usually limited by the calorimeter performance. A high granularity detector is necessary to distinguish signal particles from the background and solve the substructures to enable jet identification. The timing measurement in the calorimeter could play a relevant role in modern high-luminosity experiments that expect to record collisions with high pileups. In addition to that, the timing information improves the assignment of the calorimetric clusters to the corresponding interaction vertexes. The timing information is also relevant for removing fake signals produced synchronously or asynchronously with the bunch-crossing event. The calorimeter energy resolution is also fundamental to measuring the kinematic properties of jets.
The goal of this Research Topic is to receive high quality papers, as a way to increase the know-how of the calorimetry technique. Particular relevance themes are:
- detectors' radiation hardness
- innovative detectors' geometry
- light's transmission technique and photodetectors
- calibrations strategy
- fast acquisition systems
Keywords: Calorimeter detectors, Photosensors, Crystals, sampling
