The Great Questions in Fundamental Physics and the Detector Technology Challenges to Address them via the ECFA Detector Roadmap

• Ian Shipsey (Oxford)

Transformative discovery in science is driven by innovation in technology. Our boldest undertakings in fundamental physics have at their foundation precision instrumentation. To reveal the profound connections underlying everything we see from the smallest scales to the largest distances in the Universe, to understand its fundamental constituents, and to reveal what is still unknown, we must invent, develop, and deploy advanced instrumentation. The 2020 European Strategy for Particle Physics requested that ECFA organize a roadmap developed by the community to balance the detector R&D efforts in Europe, taking into account progress with emerging technologies in adjacent fields. The roadmap identified and described a diversified detector R&D portfolio that has the largest potential to enhance the performance of the particle physics programme in the near and long term. This talk will outline some of the great questions in particle physics and how the ECFA Detector Roadmap addresses them.

Early Career Researchers in Instrumentation

• Armin Ilg (University of Zürich)

Early Career Researchers (ECRs) play a crucial role in the LHC experiments. Since future experiments in particle physics can take decades to conceptualise, design, build and operate, today's ECRs are the leaders of tomorrow's experiments. The ECFA ECR panel conducted a survey about the training of ECRs in instrumentation. This poll however also yielded many other findings about issues of networking, recognition and diversity in instrumentation, that will as well be presented. The goal is to stimulate discussion about the needs of ECRs in instrumentation and what actions can be taken to help them.

Bolometers: powerful tools to search for rare events

• Claudia Nones (CEA/IRFU)

After a concise description of the bolometric technique, including hybrid devices with double readout, the advantages of this technology for rare event searches are highlighted and discussed. Special methods for the reduction of different forms of background are overviewed. Three examples of bolometric double-beta decay experiments, spanning a wide range of background rejection techniques, are examined in detail: CUPID-Mo, CROSS and BINGO.

Integral Concept of Sensors and Electronics – Past to Future

• Veljko Radeka (BNL)

Breakthrough advances in particle and photon detectors have occurred when the sensors were enabled by the readout electronics, and especially so when they were developed as an integral concept of charge and light sensing and low noise electronics. Some of the most successful detector systems, either in operation today or planned and being constructed for the future, have been spawned by pioneering efforts in the past. Examples in which the integral concept has led to breakthrough advances are high purity germanium gamma-ray detectors, noble liquid calorimetry and time projection chambers (both gas and liquid, most involving cold electronics. A brief glimpse at those is illustrative, but cannot be all-inclusive.
