- The fuel mix is deuterium and tritium,
燃料組合是氘和氚。
- so it's both really rare in nature and is more difficult to work with than deuterium. In fact, tritium is so rare that the world's supply is just 20 kilograms, produced as a byproduct of nuclear reactors. So, many experiments don't use it at all, and instead only use deuterium smashed into deuterium. Plus, tritium has that extra neutron—that means it produces more neutrons during a reaction than just deuterium does. So, when used by itself or in a 50:50 mix...we get a heck of a lot of neutrons to contend with. These can interfere with or damage the tools that help scientists see what's actually going on. The newest generation of scientists who are working on this experiment...have probably never worked with tritium before this. But that tricky extra neutron also means a high potential energy yield, much higher than just deuterium and deuterium.
所以它在自然界中非常罕見,而且比氘更難處理。事實上,氚是如此稀有,世界上的供應量只有20公斤,是作為核反應堆的副產品生產的。是以,許多實驗根本不使用它,而只使用砸成的氘。此外,氚有那個額外的中子--這意味著它在反應中產生的中子比單純的氘多。是以,當單獨使用或以50:50的比例混合使用時......我們會有大量的中子需要處理。這些中子會干擾或破壞幫助科學家看到實際情況的工具。從事這項實驗的最新一代科學家......在這之前可能從未與氚打過交道。但是那個棘手的額外中子也意味著一個高的潛在能量產量,比單純的氘和
