The Hyper-Kamiokande Outer Detector

The Hyper-Kamiokande (Hyper-K) experiment addresses several significant problems in fundamental physics and our understanding of the universe. One key issue is the need to unravel the mysteries surrounding neutrinos, which are elusive particles with unique properties. Neutrinos have very little mass, interact weakly with matter, and come in three flavors. However, many aspects of neutrinos, such as their masses, mixing angles, and CP-violation (a phenomenon related to the violation of combined charge conjugation and parity symmetries), are still not fully understood. The Hyper-K project aims to investigate and characterize these properties by studying neutrino oscillations using the Hyper-Kamiokande experiment. The matter/antimatter asymmetry observed in the universe is another crucial issue the Hyper-K experiment addresses. According to the Big Bang theory, equal amounts of matter and antimatter should have been produced during the universe's early stages. However, our present-day universe primarily comprises matter, with very little antimatter detected. Understanding the origin of this matter/antimatter asymmetry is fundamental in physics. The Hyper-K project aims to resolve this mystery by studying the behavior of neutrinos and their potential role in this phenomenon. The overall objectives of the Hyper-K project extend beyond fundamental research and have significant implications for society. Firstly, advancing our understanding of neutrinos and their properties contributes to the broader scientific knowledge base. It enhances our understanding of the laws governing the cosmos and provides insights into the fundamental nature of matter and the universe itself. This scientific progress can lead to breakthroughs in various fields and technologies. Technological innovation is another important aspect addressed by the Hyper-K project. The development of advanced detection systems, data analysis techniques, and sensor technologies required for the experiment can have broader applications beyond particle physics. These advancements can drive innovation in medical diagnostics, environmental monitoring, and homeland security. The technological expertise gained from the project can pave the way for future advancements that benefit society. The Hyper-K project also fosters international collaboration and cooperation. It involves scientists and researchers from different countries working together towards a common goal. This collaboration enhances the scientific outcomes and promotes cross-cultural understanding, mutual respect, and shared goals. Strengthening the global scientific community and promoting international cooperation is essential for addressing complex global challenges and advancing scientific progress. Additionally, the Hyper-K project has the potential to inspire and engage future generations. High-profile scientific projects like Hyper-Kamiokande capture the public's imagination and inspire young minds to pursue careers in science, technology, engineering, and mathematics (STEM). The project's discoveries and advancements can catalyze encouraging curiosity, promote scientific literacy, and nurture the next generation of scientists and researchers who will contribute to society through their work. The Hyper-Kamiokande experiment addresses key problems related to neutrinos and matter/antimatter asymmetry. Its significance for society lies in advancing scientific knowledge, driving technological innovation, promoting international collaboration, and inspiring future generations. By delving into the mysteries of the universe and expanding our understanding of fundamental physics, the project contributes to scientific progress, technological advancements, and the development of a curious and scientifically literate society. In conclusion, the Hyper-Kamiokande Outer Detector will be constructed based on an improved design which leverage the experience from the Super-Kamiokande analysis to increase the overall physics sensitivity of the experiment.

Project objective

This project aims to increase the mass ordering sensitivity of the future world’s largest water-Cerenkov neutrino detector Hyper-Kamiokande (Hyper-K), which is still unknown and one of the major questions in physics. I would be working on the on-going Super-Kamiokande (Super-K) atmospheric neutrino analysis, and transfer this newly acquired experience to improve the design of Hyper-K. I will focus on the Outer-Detector (OD) system, consisting of photosensors (PMTs) mounted behind the Inner Detector (ID) PMTs and facing outwards to view the outer shell of the cylindrical tank, to boost the event classification power based on their topology and improve the overall energy scale calibration to the mass ordering analysis.The project is divided into two parts which would take place in parallel: Firstly, I would work at the University of Tokyo (IPMU) with the Super-K collaboration on their atmospheric neutrino data, to improve the sample selection using the OD hits information. I would perform the first joint fit between beam and accelerator neutrinos to update and increase the significance of our knowledge of the mass ordering. At the same time I would use their neutrino laboratory to set the Quality Assurance of the OD PMTs during the incoming construction phase of Hyper-K. Working at the same time on the Super-K analysis would provide direct information for the Hyper-K OD design, to enhance the mass ordering sensitivity. In the second phase of this action I would work at King's College of London (KCL) where I will perform these sensitivity studies and train the UK groups members during the OD assembly. As I am already the OD working group convener, my strong hardware, software, and analysis skills would put me in the best position to lead this project. This new collaboration between IPMU and KCL would lead to a transfer of knowledge on the atmospheric neutrino analysis, reinforcing my position at KCL with the prospect to establish my long term academic career.
