Technology Description:

MIFTI is developing a new version of the Staged Z-Pinch (SZP) fusion concept that reduces instabilities in the fusion plasma, allowing the plasma to persist for longer periods of time. The Z-Pinch is an approach for simultaneously heating, confining, and compressing plasma by applying an intense, pulsed electrical current which generates a magnetic field. While the simplicity of the Z-Pinch is attractive, it has been plagued by plasma instabilities. MIFTI’s SZP plasma target consists of two components with different atomic numbers and is specifically configured to reduce instabilities. When the heavier component collapses around the lighter part, a shock front develops that travels faster than instabilities can grow, allowing the plasma to remain stable, long enough for fusion to occur. The approach also allows researchers to perform experiments in rapid succession, since it does not involve single-use components. MIFTI’s design simplifies the engineering required for fusion through its efficiency and reduced number of components.

Potential Impact:

If successful, MIFTI’s work will validate the SZP approach, enabling a low-cost development path towards economical fusion power.

Security:

MIFTI’s innovation could accelerate the development of cost-effective fusion reactors, which could provide a nearly limitless supply of domestic power and eliminate dependence on foreign sources of energy.

Environment:

Fusion reactors offer nearly zero emissions and produce manageable waste products. If widely adopted, they could significantly reduce or nearly eliminate carbon emissions from the electricity generation sector.

Economy:

MIFTI’s approach, if viable, could enable a low-cost path to fusion, reducing research costs to develop economical reactors.
