Abstract: Culminating in the recently announced launch of the Columbia Fusion Research Center, Fusion at Columbia has been expanding into new directions and with new partners. This presentation will discuss a mix of fundamental research carried out at Columbia, sponsored by the federal government, and research in support of the growing private fusion sector, sponsored directly by industry. Technical topics to be discussed will be in the area fusion systems design, applied plasma physics in support of fusion industry, and new initiatives in fusion technology applied to magnets, blankets, and fuel cycles. The role of partnerships will be emphasized, whether in collaboration with industry, national laboratories, or international partners.
