The research proposed for the FLF renewal grant covers and extension of the work originally undertaken in researching and developing new particle detection techniques for neutrinos and then applying them to the exciting study of neutrinos emitted from supernova, particularly those created at the beginning of the universe. These neutrinos are very interesting because they could tell us a lot about the rate and life cycle of star formation and the number of black holes in our universe all the way back to the big bang.The initial award focused on the development of novel calibration hardware for measuring tiny contamination in water, new ultra-fast photo detector technology, advanced data acquisition systems, improved triggering, and analysis algorithms to exploit a brand-new technique of doping water based Cherenkov particle detectors with Gadolinium (Gd). These advances were then to be used on the current world's largest neutrino detector Super-Kamiokande (based in Japan) to help improve the search sensitivity for these extremely rare and ancient supernova neutrino interactions, allowing us to observe them for the first time ever.Whilst this is still underway and we are eagerly looking forward to the results, the developments my group have worked on and the technology of Gd doping have also been employed on a number of other neutrino detectors to great success. These experiments with my help have produced multiple publications and advancements in many areas of science covering both hardware and software. We have also been able to produce a suite of novel synergistic software frameworks and tools to advance the field. The renewal proposes to continue to develop these systems both hardware (in terms of calibration systems and photosensors) and software (for triggering, data acquisition, analysis and particle simulation), as well as bringing the current advances and techniques to the next generation of particle physics detectors that are currently being designed and will be constructed and operated in the renewal period. These experiments are based all over the world from the USA, Europe, Japan and even the UK and aim to be technology test beds for new advances in doping materials and photosensor technology, high precision test beds for making precision particle interaction measurements and in the case of Hyper-k the new world's largest international neutrino experiment, giving us the ability to peer deeper into the universe and study the fundamental properties of the neutrinos themselves. These detectors provide an invaluable opportunity, to develop ground breaking new tools and physics, furthering our understanding. This is particularly the case with the field of supernova neutrinos, where the FLF renewal grant will allow us to ensure that the technology and hardware is developed and in place for people to study them for decades to come and raise the profile of the UKs research excellence internationally as a founding member.

FLF续批拨款的建议研究涵盖和扩展原先进行的工作，研究和开发新的中微子粒子探测技术，然后将其应用于对超新星发射的中微子的令人兴奋的研究，特别是那些在宇宙诞生之初产生的中微子。这些中微子非常有趣，因为它们可以告诉我们很多关于星星形成的速率和生命周期以及我们宇宙中黑洞的数量的信息，这些信息可以追溯到大爆炸。最初的奖项集中在开发用于测量水中微小污染的新型校准硬件，新的超快光电探测器技术，先进的数据采集系统，改进的触发，和分析算法，以开发一种全新的技术，掺杂水基切伦科夫粒子探测器与钆（Gd）。这些进展随后将用于目前世界上最大的中微子探测器Super-Kamiokande（总部设在日本），以帮助提高对这些极其罕见和古老的超新星中微子相互作用的搜索灵敏度，使我们能够有史以来第一次观察到它们。虽然这项工作仍在进行中，我们热切期待着结果，我的小组所从事的发展和Gd掺杂技术也被用于许多其他中微子探测器，取得了巨大成功。在我的帮助下，这些实验在硬件和软件的许多科学领域产生了多个出版物和进步。我们还能够开发一套新颖的协同软件框架和工具来推进该领域的发展。更新建议继续开发这些系统的硬件（在校准系统和光电传感器方面）和软件（用于触发，数据采集，分析和粒子模拟），并将当前的进步和技术带到目前正在设计的下一代粒子物理探测器中，并将在更新期间建造和运行。这些实验位于世界各地，包括美国、欧洲、日本甚至英国，旨在成为掺杂材料和光电传感器技术新进展的技术测试平台，用于进行精确粒子相互作用测量的高精度测试平台，以及新的世界上最大的国际中微子实验Hyper-k。这让我们有能力更深入地观察宇宙，研究中微子本身的基本性质。这些探测器提供了一个宝贵的机会，开发突破性的新工具和物理学，促进我们的理解。超新星中微子领域的情况尤其如此，FLF的更新拨款将使我们能够确保技术和硬件的开发和到位，以便人们在未来几十年内研究它们，并提高英国作为创始成员在国际上的研究水平。
