Present status and perspective of dual-readout calorimetry for future accelerators

Dual-readout calorimetry is a calorimetric technique able to overcome the noncompensation limit by simultaneously detecting scintillation and Cherenkov light. Scintillating photons provide a signal related to the energy deposition in the calorimeter by all ionising particles while Cherenkov photons provide a signal almost exclusively related to the electromagnetic component in the hadronic shower. Fluctuations among the electromagnetic and non-electromagnetic component of hadronic induced showers represent the major limit to reach resolutions needed in experiments at future leptonic colliders. In a dual-readout calorimeter, by looking at the two independent signals, it is possible to measure, event by event, the electromagnetic fraction and to correctly reconstruct the primary hadron energy. Applications of the dual-readout method in fiber-sampling calorimetry have been shown to be able to provide single hadron detection with an energy resolution around [Formula: see text], electromagnetic resolution around [Formula: see text], excellent particle identification capability, resulting in one of the most promising option for future leptonic colliders. Status-of-art of the dual-readout calorimetry, as well as, perspective in the developments toward scalable solution for [Formula: see text] detectors are presented in this paper. This includes, study on the material choice, SiPM readout of the fibers, possible segmentation of the fibers to enhance particle ID capability.

The Number of Power Line Spans Accounting in Determining the Induced Voltage

The article considers inductive interference components. A description of the induced voltage electromagnetic component is described in detail. The technique of the calculated wire suspension height determining based on the actual magnetic field distribution is presented. The technique for the number of power line spans determining is provided. Dependences of the magnetic field induction vector on the distance along one power line’s span are obtained. Relationships of the magnetic field induction determining error depending on the number of adjacent spans are obtained. Recommendations for the number of spans determining, which must be taken into account when evaluating the magnetic component of the power line electromagnetic field are given
