Scientific and technological advancements in detecting and analyzing quantum beam such as photons (infrared, X-rays, gamma rays), electrons, neutrons, molecules, and ions have made significant contributions in a wide range of fields, including particle and nuclear physics, astrophysics, materials science, life sciences, and medicine. In recent years, imaging technologies in these areas have seen remarkable development. Collaboration between the fields of natural sciences, engineering, and industry-academia has also progressed, leading to new breakthroughs. The purpose of our conference is to provide a platform for discussion from the perspective of "Quantum Beam Imaging (QBI)" that cuts across various fields. Then, we expect to promote the development of scientific technology and create new fields of study through interdisciplinary information exchange.
The participants of the research conference are young researchers, including graduate students, as well as researchers who actively engage in research and development in their respective fields and senior researchers who lead research groups. The conference also welcomes researchers who explore QBI technologies based on basic principles, regardless of whether they are from academic fields or aim for practical applications in industry. Therefore, in terms of presentation content, we expect discussions on state-of-the-art results of the QBI that contribute to achieving the objectives of each field, exploring the applicability based on the unique principles and know-how of each field and identifying commonalities with other fields. In other words, the audience may have an understanding of the principles of physics but may not necessarily be experts in that specific field. We would appreciate if you could keep this in mind and provide necessary introductions as needed. Additionally, if you think it useful to explain applications in the relevant field, we expect a brief overview to be provided.

In this work we review the device physics and technology of fully depleted CCDs and their use in scientific applications. Back-illuminated, 250-micron thick CCDs produced at Teledyne DALSA Semiconductor and the Lawrence Berkeley National Laboratory were developed for the U.S. Department of Energy Dark Energy projects the Dark Energy Survey and the Dark Energy Spectroscopic Instrument. Fully depleted, 650-micron thick, single-electron counting Skipper CCDs for direct Dark Matter detection projects are in use (SENSEI), in production (DAMIC-M,) and under development (OSCURA). We will also describe CCDs for fundamental radiation-detection applications, methods to improve the readout speed of single-photon detecting CCDs with applications in astronomy and quantum imaging, and process development for fully depleted CCD production on 200-mm diameter wafers.

Gamma-ray imaging is an essential tool in elucidating morphological as well as dynamical and functional features and processes ranging from tracking radiological labelled molecules in organisms to exploring nuclear phenomena in stars. Recent developments in radiation detection instrumentation, multi-sensor fusion, and data processing provide improvements in medicine, in the operation and decommissioning of nuclear facilities, in proliferation detection and emergency response, and in astrophysics covering the near as well as the far field in imaging. In parallel, advances in computer vision have enabled the realization of what we call Scene-Data Fusion (SDF) which consists of the mapping of scenes and the fusion of radiation data with the scenes in three dimensions in near real time from freely moving systems. In contrast to conventional 2D or 3D and tomographic systems which are based on static measurements and constraint motions typically on a gantry around an object, respectively, SDF can create 3D images from any freely moving platform including small ground robots or drones. In my presentation, I will introduce some of the concepts and their underlying radiation detection and imaging instruments we have developed and discuss results in areas such as Fukushima or Chornobyl in Ukraine and recent developments on quantification and semantic segmentation reflecting some of the possible extensions of the basic SDF concept.
