超高エネルギー宇宙線と福島事故環境放射線用の検出器とアルゴリズムの開発

理研所的研究活动主要包括探测器的校准以及空间应用复杂算法的设计和发展。我研究并描述了不同的检测器技术，管理硬件和软件开发。最终目标是更好地了解它们的性能，以便有可能对它们进行调整，以设计一系列负担得起的辐射探测器，从而提高公众对受福岛放射性尘降物照射地区产品安全性的认识。特别是，我参与了JEM-EUSO框架下正在开发的任务的原型制作、装配和校准测试的各种活动，例如：1。硬件：Mini-EUSO实验中使用的基于硅光电倍增管和多阳极光电倍增管等固态探测器的原型优化和测试；2.2 .校准和测试：验证信号的统计分布（暗场和平场校准），并对Mini-EUSO实验进行多次测试；3 .软件方面：开发了一套鲁棒的控制软件，用于Mini-EUSO实验机载副相机的自动数据采集；系统监测：在2017年4月nasa资助的超压气球EUSO-SPB上安装的多阳极光电倍增管数据采集系统的检查，并报告最终故障；系统集成：参与Mini-EUSO实验组装。

Research activities at RIKEN consisted mainly on calibration of detectors and the design and development of complex algorithms for space application. I studied and characterize different detectors technologies, managing both hardware and software development. The final goal is to to achieve a better knowledge of their performance so that ir will be possible to adapt them to design a series of affordable radiation detectors which will allow for increasing awareness by the general public of the safety of the products of the region exposed by the Fukushima fallout. In particular, I participated in various activities related to prototyping, assembly and calibration tests for missions under development in the JEM-EUSO framework, such as:1.Hardware: Optimization and testing of prototypes based on solid state detectors such as Silicon Photomultipliers, and Multi-Anode Photomultipliers used by the Mini-EUSO experiment; 2.Calibration and Tests: Validation of the statistical distributions of the signals (dark field and flat field calibrations) and multiple tests for the Mini-EUSO experiment;3.Software: Development of a robust control software for automatic data acquisition with the secondary cameras on board the Mini-EUSO experiment;4.System Monitoring: Check of the data acquisition system for the Multi-Anode Photomultipliers installed on the NASA-funded superpressure balloon EUSO-SPB, during balloon flight operations in April 2017 and report of eventual malfunctioning;System Integration: Partecipation to the assembly of the Mini-EUSO experiment.
