Plasma physicists from Ukraine, Germany and Japan collaborate to spark fusion power.
Despite being forced to evacuate the Kharkiv Institute of Physics and Technology due to the Russia-Ukraine war, lead author Yurii Victorovich Kovtun has collaborated with Kyoto University to create stable plasmas using microwaves. Plasmas must be maintained at the correct density, temperature, and duration for nuclear fusion to occur.

The research team, including the Max Planck Institute for Plasma Physics, has identified three critical steps in plasma production and utilized the Heliotron J device to study fusion plasma discharges. They discovered that blasting 2.45-GHz microwaves without alignment of the magnetic field produced a dense plasma, which could potentially simplify fusion research in the future.
Lead author Yurii Victorovich Kovtun, despite being forced to evacuate the Kharkiv Institute of Physics and Technology amid the current Russia-Ukraine war, has continued to work with Kyoto University to create stable plasmas using microwaves.
Getting plasma just right is one of the hurdles to harnessing the massive amounts of energy promised by nuclear fusion.
Plasmas — soups of ions and electrons — must be held at the right density, temperature, and duration for atomic nuclei to fuse together to achieve the desired release of energy.
One recipe involves the use of large, donut-shaped devices with powerful magnets that contain a plasma while carefully aligned microwave generators heat the atomic mixture. READ MORE...
