Noble Liquid Detectors and Readout Electronics: From R&D to Physics Discovery

Since the invention of the Liquid Argon (LAr) Calorimeter half a century ago, R&D on noble liquid detectors has made continuous advancements. Readout electronics has always been an integral part of detector R&D effort for precision measurement with noble liquid detectors, which plays a critical role in the discovery science in High Energy Physics experiments.

In this mini-symposium, I will begin by introducing the LAr Calorimeter and its readout electronics system, highlighting the significant contribution to the Higgs boson discovery in 2012. I will discuss the exceptional performance of the recently upgraded ATLAS calorimeter trigger readout electronics system and provide updates on the ongoing upgrade of the ATLAS LAr Calorimeter readout electronics for the HL-LHC era.

The focus will then shift to nearly two decades of R&D on readout electronics systems for accelerator-based neutrino experiments, emphasizing the role of CMOS-based cryogenic readout electronics as the enabling technology or giant (>10 kT) LAr Time Projection Chamber (LAr TPC). I will showcase the outstanding performance of LAr TPC detectors, including MicroBooNE, SBND, and ProtoDUNE, and share updates on the construction of the two LAr TPC far detector modules for the DUNE experiment.

Finally, I will present the concept of a new noble liquid calorimeter for ALLEGRO, proposed for the FCC-ee. This innovative development opens exciting new R&D opportunities for the young generation of researchers.
