Plans for MTF demonstration facility

General Fusion is developing Magnetized Target Fusion (MTF). After years of developing the various subcomponents of our system, we are set to build a large integrated prototype at the UKAEA Culham Campus. The precompression plasma will be a spherical tokamak with a major radius of 0.77 m and a minor radius of 0.72 m. The initial density will be ~5x10¹⁹ m^-3. Compression will be provided by a liquid lithium rotating core that opens the initial 3 m diameter cavity by centrifugal forces. An array of pneumatic cylinders surrounding the rotating core will compress the fluid to reduce the dimension of the cavity by a volume factor of 1000 in 5 ms, compressing the plasma to a density of 5x10²² m^-3 and a temperature of 10 keV, achieving around 10% of the Lawson criteria.

I will describe the machine, the results of some preliminary tests of some parts of the design and some simulations.
