Description
Future high luminosity particle physics experiments come with many challenges. In hadron machines high pile-up rates will drive down the efficiencies of current calorimeters if timing information is not added to energy measurements. In general, detectors aspiring to be sensitive to flavor physics observables or flavor-tagged jets require hadron identification systems capable of distinguishing hadron species over a broad momentum range. A time resolution of the order or below ten picoseconds will allow for particle identification systems to achieve the physics goals with detectors located not too far from the beam axis. The introduction of low gain avalanche diodes (LGADs) to particle identification will improve time of flight measurements and calorimeter shower reconstruction, but special care has to be taken when adapting the technology for large-area detectors. We explore the feasibility of using large-area LGADs for a timing/imaging layer within a silicon-based sampling calorimeter, taking care to account for the specifications and specialized segmentation required for such a detector.
