Abstract:
This seminar talk will focus on one of the instrumentation frontiers for elementary particle detection, namely “calorimetry”, in the context of precision experiments at future lepton colliders.Firstly, a brief introduction will be given on the calorimetryprinciples, followed by selected examples of legendary calorimeters in the particle physics. Secondly, high-granularity calorimetry at the cutting edge for future lepton colliders will be presented, including highlights of comprehensive shower performance studies, andlatest developments of technological prototypes within the CALICE collaboration to address major technical challenges. Lastly, synergies andother successful applications of highly granular calorimeters will also be briefly covered.
Biography:
Dr. Yong Liu received his Bachelor and Ph.D. degrees at Wuhan University in 2006 and at the Institute of High Energy Physics (IHEP, CAS) in 2011, respectively. As a postdoctoral research associate, he first worked at Justus Liebig University Giessen in Germany on an ultra-fast timing detector for an ATLAS upgrade project, and later at Johannes Gutenberg University Mainz since 2012 on the high-granularity calorimetry development for future lepton colliders within the CALICE Collaboration. He made major contributions including the “SiPM-on-tile” design, comprehensive characterizations of SiPMs and a full electronics system integrated with ASICs, and development of test-stands, which were crucial to a large-scale technological prototype for a high-granularity calorimetry option. In 2018, he joined the IHEP as a faculty member and since then worked on the instrumentation frontier of calorimetry, especially for the Circular Electron Positron Collider (CEPC)and the CMS Phase-2 end cap calorimeter upgrade project (HGCAL).
