OpenStar Tahi: Putting the levitated dipole on the Lawson curve

Previous generations of levitated dipole experiments have proved that the desirable properties of magnetospheric dipole plasma confinement can be reproduced in laboratory-sized experiments on Earth. OpenStar Technologies is a start-up company investigating the levitated dipole as a concept for commercial fusion energy production. On the path to net energy-production, OpenStar plans to build multiple devices to validate both the physics basis for dipole-confined fusion plasmas and the engineering technology required for future dipole reactors. OpenStar has completed the construction of their first device, "Junior", along this development pathway, and is now in the early stages of designing the next-generation machine, "Tahi". Previous levitated dipole experiments (e.g. LDX, RT-1, Junior) confine warm electron plasmas but lack the heating power density to achieve a warm, thermal ion population. Tahi is planned to be the first example of a levitated dipole reactor that produces a fusion 'relevant' plasma, helping to validate predictions of their performance made by physics models. This work details a conceptual design for Tahi, including its engineering specifications and predicted performance.
