Scientists in Germany switch on nuclear fusion

Scientists in Germany flipped the switch on an experiment they hope will advance the quest for nuclear fusion, considered a clean and safe form of nuclear power.

Following nine years of construction and testing, researchers at the Max Planck Institute for Plasma Physics in Greifswald injected a tiny amount of hydrogen into a doughnut-shaped device—then zapped it with the equivalent of 6,000 microwave ovens.

The resulting super-hot gas, known as plasma, lasted just a fraction of a second before cooling down again, long enough for scientists to confidently declare the start of their experiment a success.

"Everything went well today. With a system as complex as this you have to make sure everything works perfectly and there's always a risk," said Robert Wolf, a senior scientist involved with the project.

Among the difficulties is how to cool the complex arrangement of magnets required to keep the plasma floating inside the device, Wolf said.

Scientists looked closely at the hiccups experienced during the start-up of the Large Hadron Collider in Switzerland more than five years ago to avoid similar mistakes, he said.

The experiment in Greifswald is part of a world-wide effort to harness nuclear fusion, a process in which atoms join at extremely high temperatures and release large amounts of energy that's similar to what occurs inside the sun.
