ITER project ranks as the most ambitious science endeavors of our time. Building began in 2010 in France where 34 nations are collaborating to realize the ITER project's First Plasma in November 2020.The international nuclear fusion project known as ITER, meaning "the way" in Latin is based on the 'tokamak' concept of magnetic confinement, in which the plasma is contained in a doughnut-shaped vacuum vessel.ITER is a step towards future production of electricity from fusion energy. Nuclear Fusion is the process in which the Sun and the stars produce the energy by fusing light nuclei of hydrogen. ITER will produce at least ten times more energy than the energy required to operate it. In future demo or commercial reactors based on fusion, this energy can be converted to electricity. 

• The fuel-a mixture of deuterium and tritium, two isotopes of hydrogen-is heated to temperatures in excess of 150 million degrees Celsius forming a hot plasma.
• The temperature within the gigantic machine will, therefore, reach 10 times the temperature at the core of the Sun.
• Strong magnetic fields will be used to keep the plasma away from the walls.
• India will be one of the significant creators of the Tokamak which will weigh 23,000 tons-as heavy as three Eiffel Towers-with a plasma volume of 840 cubic metres.
• The main feature of the 180 hectare ITER site in Cadarache, southern France, is a man-made level 42 hectare platform that would be 1 kilometre long and 400 metres wide, and compares in size to 60 soccer fields.
• As stipulated in the agreement that the ITER Organization and the Indian Domestic Agency signed on 19 April, this small "territory"-the size of a football field-will be made available to the Indian Domestic Agency.

When India joined the ITER project in 2005, the Institute for Plasma Research (IPR) at Gandhinagar was entrusted by the government of India with managing participation in ITER.
