ST40 assembly time-lapse



A time-lapse video showing the ST40 tokamak being built over 111 days.


This is ST40 - a novel, high-field spherical tokamak that was designed, constructed and commissioned on a short timescale.

The ST40 aims to demonstrate rapid progress towards fusion energy from compact tokamaks.

This is the constuction phase before hot plasma operations.

ST40 will demonstrate fusion temperatures in a small machine and prove that the development of fusion energy can be accelerated using compact tokamaks.
