Title：Research and development of a Ring Imaging Cherenkov detector(RICH) for using in a charmed baryon spectroscopy experiment.
Abstract：A hadron is a particle that consists of quarks and antiquarks bound together by the strong interaction. Hadrons are classified into baryons, which are made up of three quarks, and mesons, which are composed of a quark and an antiquark. However, recent research has discovered states known as exotic hadrons, which are thought to be composed of four or more quarks. The discovery of states that cannot be explained by traditional theories suggests that the internal structure of hadrons is more diverse than previously thought. The correlation between two quarks, diquark correlation, is considered to be a significant factor. Currently, the J-PARC E50 experiment (MARQ experiment) is planned for clarification of diquark correlation. In this presentation, I will introduce the detectors used in the MARQ experiment, particularly those that I have been involved in developing.

Title: Assessment of Fundamental Characteristic of Monitor for Carbon Ion FLASH Therapy
Abstract:
Recently FLASH radiation therapy (FLASH-RT) has been conducted in the world. The name of FLASH-RT comes from FLASH effect, which is induced from irradiation whose dose rate is over 40 Gy/s and that dose rate is 1000 times larger than conventional dose rate. FLASH-RT is superior to conventional-RT in the way that it can reduce radiation-induced damage in healthy tissue and retain antitumor effectiveness. However, that mechanism is unrevealed especially in the field of carbon ion RT (CIRT) because there are few research facilities in the world. To reveal that and conduct FLASH CIRT in the future, we need to construct experimental and treatment setup. First, we assess the characteristic of monitor for dose monitoring about ion recombination.
