Noble liquid technologies at the frontier of particle physics

In the field of particle and astroparticle physics, noble liquid detector technologies have emerged as one of the most commonly adopted approaches for the detection of rare events, enabling unprecedented sensitivity in the detection of neutrino interactions, searches for dark matter, and searches for other physics beyond the Standard Model. They have found remarkable implementations in high-energy physics calorimetry too. From the early development of liquid noble detectors to the sophisticated dual-phase Time Projection Chambers (TPCs) and large-scale calorimeter systems currently used in leading experiments worldwide, these technologies have continuously evolved to meet the growing demands for scalability, radiopurity, and signal discrimination and reconstruction.Recent advances in the detection of rare events, involving enhanced light and charge readout techniques, cryogenic electronics, and novel amplification concepts have significantly expanded the capabilities of noble liquid detectors. In particular, the development of innovative structures for photon and ionization signal detection, alongside improved integration strategies for single- and double-phase TPCs, have enhanced detector stability, energy resolution, and background rejection. At the same time, the optimization of primary scintillation processes, the use of dopants to tailor detector response, and the pursuit of ultra-radiopure materials are opening new avenues for next-generation experiments. The exploration of amplification mechanisms in single-phase detectors, together with the emergence of new cold electronics and ASIC technologies capable of operating reliably at cryogenic temperatures, is driving the field toward more compact, efficient, and scalable detector architectures. Pixel-based charge detection, enabling an unambiguous 3D readout of ionizing particle trajectories, has emerged as a particular point of recent innovation. Bubble chamber technologies, which continue to provide exceptional background discrimination capabilities, also remain a key area of innovation and development.Complementing these advances, developments in liquid-argon calorimetry for high-energy physics include high-dynamic-range readout electronics, long-term stability, radiation-tolerant components, and high-throughput signal processing, further expanding the technological capabilities and potential applications of noble-liquid detectors at the high-energy/high-rate frontier.This Research Topic aims to advance the development and application of noble liquid technologies for particle detection, with a particular focus on novel concepts, detector integration, and enabling technologies for future large-scale experiments. Emphasis is placed on improving detector performance, stability, scalability, radiopurity, radiation tolerance, and readout capability across both low-background and high-rate cryogenic environments. Particular attention is given to innovative approaches to light and charge detection, detector integration, and cryogenic electronics.To gather further insights into detector technologies, system integration, and material performance, we welcome articles addressing, but not limited to, the following themes:- Light and charge readout: new structures and concepts- Double- and single-phase TPCs: integration, system aspects, and novel designs- Bubble chamber technologies- Radiopurity and low-background techniques- Primary scintillation processes- Dopants and detector response optimization- Liquid-argon calorimetry for collider experiments- Amplification of ionization signals in single-phase detectors- New cold electronics and ASIC developments for cryogenic applications Topic editors: André Cortez, Pablo Amedo Martinez, Ander Simón Estévez, Angela Fava, Gray Putnam Source: https://www.frontiersin.org/research-topics/83835/noble-liquid-technologies-at-the-frontier-of-particle-physics
