俺說的是那個fusion ignition。猜猜用的什麽材料？

還是氘和氚的混合物。

 

Lawrence Livermore National Laboratory has its 1.8 MJ laser system running at full power. This laser system is designed to compress and heat a mixture of deuterium and tritium, which are both isotopes of hydrogen, in order to compress the isotopes to a fraction of their original size and fuse them into helium atoms (releasing neutrons in the process).^[6]
