Abstract
International collaboration on complex plasmas was established in 2007. Since then, the Japanese science team joined microgravity experiments using PK-3 Plus on the International Space Station (ISS). Our main objective is to investigate the critical phenomena of charged systems. Operational conditions, based on the original theory and ground-based experiments, were proposed to the international science team. As a result, we successfully obtained opportunities of microgravity experiments. The operation on the ISS was terminated in 2013. The Japanese team continued analyzing the data to summarize the microgravity experiments by the end of March, 2014. A new apparatus PK-4 has already installed on the ISS and the operation begins. We are now seeking new objectives suitable for PK-4.
