Diagnostics for super-hot plasmas in fusion reactors
Phys.org January 30, 2017 It’s tough to measure the concentration of the single or neutral hydrogen atoms in fusion plasmas. The temperatures reach tens of thousands of degrees or more. A new calibration technique to improve these measurements uses different fluorescence pathways in a laser-induced fluorescence measurement system. Xenon (blue) and krypton (red) fluorescence have … Read more
