With the completion this autumn of a multiyear campaign to repair key tokamak components, ITER is closing a difficult chapter ...

Aparajita Mukherjee joined the Institute for Plasma Research, Gandhinagar, in 1991 as a research scholar after obtaining her master’s degree in physics from Jadavpur University. Her initial research ...

The open licence will allow a broader group of scientists to contribute to and validate the JOREK code against experiments.

The new baseline replaces the plan that had been used as a reference since 2016, and which for some time had been publicly acknowledged to be no longer "feasible, practical or optimal." The major ...

In the West, scientists were founding their expectations on machines such as the Perhapstron in the US or Zeta (Zero Energy Thermonuclear Assembly) in the United-Kingdom—machines that used strong ...

There are many species of impurities, but one of the most deleterious is oxygen, which originates from the inevitable oxidation process in the materials inside the vacuum vessel. Oxygen release into ...

ITER ("The Way" in Latin) is one of the most ambitious energy projects in the world today.

After the successful lift of tokamak sector module #1 at the end of July, focus has shifted to the next-in-line: sector module #9. Each of the tokamak’s nine modules has three main elements—a vacuum ...

The vacuum vessel thermal shields and the cryostat thermal shields are actively cooled silver-plated elements, 20 and 10 millimetres thick respectively, that contribute to thermally insulating the ...

The only source of readily available tritium comes from heavy-water fission reactors such as the CANDU type (developed by Canada in the 1950-60s, and adopted since in Romania, South Korea, and India).

WEST is more than an upgrade from the quarter-century-old Tore Supra tokamak: it is a reinvented machine that now serves as a test bench and risk-limiter for ITER. Having replaced its previous ...
