JT-60(JT stands for Japan Torus)是日本日本原子力研究所(目前是日本原子能研究開發機構(JAEA))的超導托卡馬克核融合裝置,1985年開始運作。[2][3]

JT-60是具有一个D形极向截面的托卡马克,类似于歐洲聯合環狀反應爐(JET)。由反应堆得到的实验结果对于国际热核聚变实验反应堆(ITER)实验以及未来的托卡马克装置有重要意义。

2006年5月9日,JAEA宣布JT-60已达到28.6秒的等离子体持续时间[4]。JAEA在JT-60中使用新的部件,已经提高了在其强大的纵向磁场保存等离子体的能力。

JT-60SA

在2010年JT-60已被拆卸,然后通过使用铌-钛英语Niobium-titanium超导线圈被升级到JT-60SA[2][5]。JT-60SA的建设于2013年正式开始,2020年3月完成主体装置建造[6]。2021年3月完成纵场磁铁测试[7]

2023年10月23日,日本量子科學技術研究開發機構發佈消息稱,在日本國內的實驗設施中確認了等離子體,實現了被稱為「First Plasma」的第一階段[8][9]

Mass per unit volume of the Earth's atmosphere The density of air or atmospheric density, denoted ρ, is the mass per unit volume of Earth's atmosphere. Air density, like air pressure, decreases with increasing altitude. It also changes with variations in atmospheric pressure, temperature and humidity. At 101.325 kPa (abs) and 20 °C (68 °F), air has a density of approximately 1.204 kg/m3 (0.0752 lb/cu ft), according to the International Standard Atmosphere (ISA). At 101.325&#...
