Abstract:
In 2029, LHC will enter the High Luminosity phase with five times higher instantaneous luminosity, creating a unique chance to explore new physics beyond the standard model.
With the increasing instantaneous luminosity at the LHC, many proton-proton collisions occur simultaneously in one bunch crossing, giving severe challenges for detectors to identify interaction vertices from pile-up.
At ATLAS, a Low Gain Avalanche Diode (LGAD) based High Granularity Timing Detector (HGTD) has been proposed and approved to be installed during LS3 (2026-2028) before the end-cap LAr calorimeter and after the new Inner Tracker (ITK), for pile-up mitigation and for per bunch luminosity measurement.
In this seminar, I will give an overview of the current status of the HGTD project, as well as sharing my visions for developing fast timing detectors beyond the Run 4.
Resume:
Dr. Mengqing Wu is an assistant professor at the Radboud University and a staff scientist at Nikhef. Her recent work focuses on frontier fast timing sensor R&D and next generation detector system design, as well as searches of new phenomena such as Majorana neutrinos.
Currently, she is leading a subgroup of the ATLAS phase-II High Granularity Timing Detector project, responsible for detector control (DCS), readout (DAQ), safety (DSS) and luminosity systems; besides, she is leading efforts within the ATLAS TDAQ community to deploy the FELIX system in the ATLAS MDT readout (MROD).
In 2015, she obtained her Ph.D degree from the Université Grenoble Alpes. Her thesis work focuses on searches of SUSY and dark matter in a single phone final state at ATLAS. As a member of the LHC dark matter working group, she has made important contribution to set up dark matter benchmark models to guide the Run 2 searches.
She later joint the CMS experiment as a Chung-Yao Chao fellow at IHEP, coordinating the efforts to validate software releases for CMS and searching for new di-boson resonances.
In 2017, she joint DESY as a project scientist to lead tasks in the EU Horizon 2020 research and innovation program, AIDA-2020. She has led a small dynamic group to deliver an innovative silicon strip beam telescope and a slow control system, both of which are installed as part of DESY Test Beam facility.
