Billions of dollars are spent on research in the field of laser thermonuclear fusion all over the world. What is laser thermonuclear fusion (LTS)? Why is it needed and what successful experiments have already been done? Speaker: Mikhail Leonidovich Shmatov, Doctor of Physical and Mathematical Sciences, Senior Researcher at the Laboratory of Solid State Theory of Ioffe Institute.
Controlled thermonuclear fusion, including laser fusion, can be used to develop energetics of the future and for other purposes. The plasma heating temperature for igniting a reaction of this type can reach 140 million degrees Celsius. In the entire history of science, no one has been able to ignite a thermonuclear target in a laboratory until now, and today thousands of specialists around the world are working on this task.
