What is it about?

Design and implementation of a diagnostic for MAST Upgrade. The diagnostic observes and maps the radiation around the lower x-point. Because of using a camera rather than a single electrical sensor, there is a large number of available lines of sight. The tomographic inversion from line integrated to emissivity can be done with a far greater resolution.

Why is it important?

This is the first diagnostic ever to achieve such a high resolution round the x-point, and even more so in spherical tokamaks.


This publication is a solid foundation for the design and optimisation of similar diagnostics, and showcases the capabilities and pitfalls of this system.
