Nuclear Fusion Breakthrough Reach 100 Million Degree Celsius

VoxPop – A British company has made history after successfully realizing a nuclear fusion reaction using a spherical Tokamak machine called ST40. The resulting fusion reaction reached temperatures of 100 million degrees Celsius, hotter than the Sun.
Scientists around the world are obsessed with realizing nuclear fusion reactions, like those that occur on the Sun, to produce clean energy.
They build sophisticated machines or equipment that can realize nuclear fusion reactions at temperatures around 100 million degrees Celsius.
This temperature is the threshold at which hydrogen atoms can begin to fuse into helium, which is then converted into energy.
For this reason, the Tokamak machine developed is often referred to as an artificial Sun, as it is capable of producing fusion reactions and has a temperature of 100 million degrees Celsius just like the real Sun.

British scientists based in Oxfordshire in collaboration with researchers at Princeton's Plasma Physics Laboratory were able to realize the fusion reaction with the Tokamak ST40 machine.
"Ion temperatures over 100 million degrees Celsius have been generated in the compact ST40 high-field spherical Tokamak," the research team said in a new paper published in the journal Nuclear Fusion.
This was achieved using the ST40 spherical Tokamak, an apple core-shaped nuclear device in Oxfordshire.
This reactor is smaller and operates with less plasma heating power, but could pave the way for the first fusion power plant.
"Such temperatures have never been achieved in a spherical Tokamak. These temperatures can only be obtained in much larger devices with much greater plasma heating power," the researchers said.
The Tokamak ST40, first unveiled in April 2017, is spherical and more compact than the flatter and larger doughnut-shaped reactor. It was built by the Tokamak Energy company, based in Milton, Oxfordshire, to recreate the nuclear fusion process on the Sun.
