Technique to study the extreme ultraviolet light emitted by a fusion plasma

What is it about?

Nuclear fusion is an alternative to traditional nuclear fission and is a promising future energy source for humanity. Despite the numerous benefits of carbon-neutral, safe, and environmentally friendly fusion energy, several enabling technologies have yet to be developed. This publication is about the technology needed to diagnose a fusion plasma. By studying the extreme ultraviolet light emitted by the plasma it is possible to measure the plasma temperature, density, and other important parameters in a fusion generator.

Why is it important?

We outline the spectroscopy technology needed to study the extreme ultraviolet radiation emitted from a fusion plasma. This is important for humanities efforts to replace fossil fuels with safe, clean, and scalable solutions such as fusion energy. This work is important because it describes the complex techniques needed to measure the physical parameters inside a fusion generator.
