self-driven current regimes with a flexible array of heating, current drive, and rotational drive systems, with good profile measurements.


IGNITOR, an Italian project, is a compact, cryogenically cooled, copper-magnet device capable of operation at high magnetic field. It is designed to achieve ignition in D-T plasmas and to study alpha-particle confinement and the heating and control of ignited plasmas. While potentially cost-effective in achieving the burning plasma regime, the resulting plasma conditions and flexibility of the device are more limited in the reactor-relevant physics that can be addressed. The IGNITOR design also raises a number of concerns, including less well established performance projections, questions about whether the required peak pressure profiles can be realized, and issues surrounding the structural integrity of the vessel.2
