Abstract:
The Semi-Digital Hadronic Calorimeter (SDHCAL) is a calorimeter concept that was developed within the CALICE collaboration for future lepton colliders and in particular for the International Linear Collider (ILC). The SDHCAL uses the high granularity that gaseous detectors such as Glass Resistive Plate Chambers (GRPC) could provide to apply the Particle Flow Algorithms (PFA) techniques aiming at excellent Jet Energy Resolution (JER). In this seminar we will show the different phases of the construction of a large SDHCAL prototype based on this concept and the results we obtained in several beam tests at CERN. We will also explain the current R&D to transform the SDHCAL into a 5D calorimeter called T-SDHCAL by exploiting the time resolution the multi-gap version of the RPC and how this will extend the capabilities of the concept. We will also discuss the transformation one needs to adapt the T-SDHCAL to circular colliders environments and in particular to those related to the Z-pole scenario.
About the speaker:
Imad laktineh is professor at the University of Lyon and senior researcher at the Institut des deux infinis de Lyon (IP2I). His main activities are on detector R&D for the experiments of future high-energy colliders (HL-LHC, ILC, CEPC and FCCee ). He developed the concept of the Semi-Digital Hadronic Calorimeter SDHCAL and led the construction of the first technological prototype of the CALICE collaboration using this concept. He is currently working on including the time information in this concept (T-SDHCAL) to improve on the Particle Flow Algorithms (PFA) techniques. He also initiated the CMS- iRPC project proposing a new RPC readout concept. He has recently invented the PICMIC concept that intends to fully exploit both the excellent spatial and time resolutions of the MCP devices. In parallel, he is developing similar devices with much better performances named NCP for NanoChannel Plates.
Pr. Laktineh is very active in the new DRD collaborations with leading roles in DRD1(gaseous detectors), DRD4 (photo-detection) and DRD6 (calorimetry). He is currently the scientific adviser of the CNRS-I2P3 for innovative detectors and quantum technologies.
