Tungsten is one of the reference plasma-facing materials in fusion power devices due to its excellent temperature resistance and low tritium retention. The investigation of the electronic structure is key for implementing tungsten-based technologies as it is strongly related to the stability and properties of the material. However, despite the large efforts in studying the electronic properties of tungsten metal, some complex features are still not properly characterised.
The combination of state-of-the-art experimental and theoretical approaches is key to describing the electronic structure of tungsten, as presented in a recent publication in Physical Review B, entitled “Lifetime effects and satellites in the photoelectron spectrum of tungsten metal“.
