Stellarator
A stellarator confines Plasma (physics), plasma using external magnets. Scientists aim to use stellarators to generate fusion power. It is one of many types of magnetic confinement fusion devices. The name "stellarator" refers to stars because fusion mostly occurs in stars such as the Sun. It is one of the earliest human-designed fusion power devices. The stellarator was invented by American scientist Lyman Spitzer in 1951. Much of its early development was carried out by Spitzer's team at what became the Princeton Plasma Physics Laboratory (PPPL). Spitzer's Model A began operation in 1953 and demonstrated plasma confinement. Larger models followed, but demonstrated poor performance, losing plasma at rates far worse than theoretical predictions. By the early 1960s, hopes of producing a commercial machine faded, and attention turned to studying fundamental theory. By the mid-1960s, Spitzer was convinced that the stellarator was matching the Bohm diffusion rate, which suggested i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kyoto University
, or , is a National university, national research university in Kyoto, Japan. Founded in 1897, it is one of the former Imperial Universities and the second oldest university in Japan. The university has ten undergraduate faculties, eighteen graduate schools, and thirteen research institutes. The university's educational and research activities are centred in its three main campuses in Kyoto: Yoshida, Uji and Katsura. The Kyoto University Library Network, consisting of more than 40 libraries spread across its campuses, has a collection of more than 7.49 million books, making it the second largest university library in the country. In addition to these campuses, the university owns facilities and lands for educational and research purposes around the country. As of 2024, Kyoto University counts List of prime ministers of Japan by education, two prime ministers of Japan amongst its alumni.
