Francis F. Chen
Francis F. Chen (born November 18, 1929) is a Chinese-born American plasma physicist and electrical engineer. Early life and education On November 18, 1929, Chen was born in Guangdong, Guangdong province, China. Chen studied at Harvard University, where he received his bachelor's degree in astronomy in 1950, a master's degree in physics in 1953, and his doctorate in 1954. At that time he worked on high-energy physics (proton-proton scattering and proton-nucleus scattering at the new energy of 1 GeV). Career In 1954, Chen worked at the Princeton Plasma Physics Laboratory (PPPL), where he worked initially with the Model B1 Stellarator, a device used to confine hot plasma with magnetic fields in order to sustain a controlled nuclear fusion reaction. With the B1 Stellarator, Chen was the first to show that electrons could be trapped by a magnetic field for millions of traverses. Chen remained at PPPL until 1969. In 1969, Chen became a professor of electrical engineering at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guangdong
Guangdong (, ), alternatively romanized as Canton or Kwangtung, is a coastal province in South China on the north shore of the South China Sea. The capital of the province is Guangzhou. With a population of 126.01 million (as of 2020) across a total area of about , Guangdong is the most populous province of China and the 15th-largest by area as well as the second-most populous country subdivision in the world (after Uttar Pradesh in India). Its economy is larger than that of any other province in the nation and the fifth largest sub-national economy in the world with a GDP (nominal) of 1.95 trillion USD (12.4 trillion CNY) in 2021. The Pearl River Delta Economic Zone, a Chinese megalopolis, is a core for high technology, manufacturing and foreign trade. Located in this zone are two of the four top Chinese cities and the top two Chinese prefecture-level cities by GDP; Guangzhou, the capital of the province, and Shenzhen, the first special economic zone in the count ...

Stellarator
A stellarator is a plasma device that relies primarily on external magnets to confine a plasma. Scientists researching magnetic confinement fusion aim to use stellarator devices as a vessel for nuclear fusion reactions. The name refers to the possibility of harnessing the power source of the stars, such as the Sun. It is one of the earliest fusion power devices, along with the z-pinch and magnetic mirror. The stellarator was invented by American scientist Lyman Spitzer of Princeton University in 1951, and much of its early development was carried out by his team at what became the Princeton Plasma Physics Laboratory (PPPL). Lyman's Model A began operation in 1953 and demonstrated plasma confinement. Larger models followed, but these demonstrated poor performance, losing plasma at rates far worse than theoretical predictions. By the early 1960s, any hope of quickly producing a commercial machine faded, and attention turned to studying the fundamental theory of high-energy plasma ...
