Description
Run 3 of the Large Hadron Collider has just ended, and the machine will undergo an upgrade to increase the instantaneous luminosity by over a factor of three. The High-Luminosity phase (HL-LHC) will enable the collection of data sets of unprecedented size for the precision study of fundamental physics. However, the luminosity increase poses a substantial challenge for the experiments, which have to face increased levels of radiation and of overlapping interactions. The ATLAS experiment will undergo a major upgrade program and will feature, for the first time, a dedicated High Granularity Timing Detector (HGTD) instrumenting the forward detector regions. The HGTD is designed to provide charged particle track timing information with a resolution of 30-50 ps over its lifetime. This seminar will review the design of the HGTD detector, the key results recently achieved, and the status of the project towards construction.
