PLASMA PHYSICS:
Requiem for a Heavyweight at Meeting on Fusion Reactors
James Glanz
MADISON, WISCONSIN--The dimming prospects for the full-scale, $10 billion version of the proposed International Thermonuclear Experimental Reactor were all but extinguished here last week during a meeting of fusion experts. Not only did the design find almost no support among U.S. scientists, but for the first time, a representative from Japan's fusion program openly floated designs for a smaller and less ambitious international machine. This roughly half-price version, unlike the original proposal, would not be designed to generate the self-sustaining fusion burn called ignition.
