ITER is a vast subject that will take time to explore. Every few months we hope you’ll look forward to receiving news from the frontiers of ITER science and technology, the enterprising world of high-precision industry, and from the hilltop in Provence where it’s all coming together.

This magazine is for you. We’d be happy to receive your suggestions and remarks for its improvement at the email address listed below.

DEMO is the machine that will bring fusion energy research to the threshold of a prototype fusion reactor. After ITER—the machine that will demonstrate the technological and scientific feasibility of fusion energy—DEMO will open the way to its industrial and commercial exploitation.

ITER ... and then what?

In the world of fusion research, experimental programs aren't carried out consecutively ... they overlap. Physicists were already trying to imagine ITER (under the name of INTOR) when construction of the European JET tokamak was just getting underway in the early 1980s; now, work is underway on the conception of the next-stage machine, DEMO, while the ITER installation is still years from finalization.
Dedicated to "Man's Achievement on a Shrinking Globe in an Expanding Universe," the 1964 New York World's Fair opened on 22 April in Flushing Meadows. One of its most spectacular attractions was General Electric's Progressland where the Fusion Demonstration was performed non-stop.

When fusion was (almost) there

Fifty years ago, in 1964, human beings believed in progress. Manned space capsules were routinely sent into space, a revolutionary supersonic commercial airliner was nearing the prototype stage, the computer mouse had just been invented, and the official decision had been taken to build a cross-Channel tunnel.
Four thousand tons of reinforcement will form the "skeleton" of the basemat that will support the Tokamak Complex. Steel density is at its highest in the central area (one fourth of the total rebar).

Spider webs of steel

In the middle of the Tokamak Complex Seismic Pit a vast circle is now visible, part of the complex reinforcement work underway for the B2 foundation slab. Once in place, 16 levels of 40-millimetre-thick rebar will support the weight of the machine.

Who "invented" fusion?

The droves of visitors who come to see the ITER site every yearoften ask: "Who discovered (or invented) fusion?"
