Conference Report on the 7th International Symposium on Liquid metals Applications for fusion (ISLA-7)

Supported by the world magnetic fusion research community, a series of International Symposia on Liquid metals Applications for fusion (ISLA) have been held biannually over the past 15 years or so. The 7th edition (ISLA-7) was held for the period from Dec. 12th through Dec. 16th, 2022, at Chubu University located in Kasugai, Aichi, Japan. For the first time in the history of this series of symposia, ISLA-7 was held in a hybrid fashion, due to the COVID-19 situation. The total number of the participants was 60, 34 out of whom attended the symposium in person, and the rest participated online. As to the presentation statistics, 29 papers were presented in person, whereas 21 presentations were delivered online but real-time by the presenters in China, Spain, the UK, and the USA. Both of the presentations delivered in person and online were recorded, and the video has been shared by all participants. These participants represent 11 countries: China, Czech, Italy, Japan, Latvia, Netherlands, Russia, Thailand, the UK, and the USA. All these numbers are among the largest in this series of symposia. Covered by these presentations are; in Session-2, Program overviews and liquid metal research review; in Session-3, Liquid metal flows, and MHD issues; in Session-4, Liquid metal facilities; in Sessions-5 and 6, Liquid metal experiments and modeling-I and II; in Session-7, Divertor physics and heat flux mitigation; in Session-8, Plasma and liquid metals interactions; in Session-9 Liquid metal plasma-facing components, erosion, and wettability. In addition, there were an opening session whereby several opening addresses were delivered. Finally, during the closing session all technical session summaries were presented, and the next symposium ISLA-8 has been decided to be held in 2024 in China, given the COVID-19 situation has been resolved by then, otherwise it will be held in the Netherlands.
