History of Fusion Energy Research
The fusion process has been studied in order to understand nuclear matter and forces,to learn more about the nuclear physics of stellar objects,and to develop thermonuclear weapons.During the late 1940s and early1950s,research programs in the United States,United Kingdom,and the Soviet Union began to yield a better understanding of nuclear fusion,and investigators embarked on ways of exploiting the process for practical energy production.Fusion reactor research focused primarily on using magnetic fields and electromagnetic forces to contain the extremely hot plasmas needed for thermonuclear fusion.
Researchers soon found,however,that it is exceedingly difficult to contain plasmas at fusion reaction temperatures because the hot gases tend to expand and escape from the enclosing magnetic structure.Plasma physics theory in the 1950s was incapable of describing the behaviour of the plasmas in many of the early magnetic confinement systems.
The undeniable potential benefits of practical fusion energy led to an increasing call for international cooperation.American,British,and Soviet Unions fusion programs were strictly classified until 1958,when most of their research programs were made public at the Second Geneva Conference on the Peaceful Uses of Atomic Energy,sponsored by the United Nations.Since that time,fusion research has been characterized by international collaboration.In addition,scientists have also continued to study and measure fusion reactions between the lighter elements so as to arrive at a more accurate determination of reaction rates.The formulas developed by nuclear physicists for predicting the rate of fusion energy generation have been adopted by astrophysicists to derive new information about the structure and evolution of stars.
Work on the other major approach to fusion energy,inertial confinement fusion(ICF),was begun in the early 1960s.The initial idea was proposed in 1961,only a year after the reported invention of the laser,in a then-classified proposal to employ large pulses of laser energy(which no one then quite knew how to achieve)to implode and shock-heat matter to temperatures at which nuclear fusion would proceed vigorously.Aspects of inertial confinement fusion were declassified in the 1970s and,especially,i the early 1990s to reveal important aspects of the design of the targets containing fusion fuels.Very painstaking and sophisticated work to design and develop short-pulse,high-power lasers and suitable millimetre-sized targets continues,and significant progress has been made.
Although practical fusion reactors have not been built yet,the necessary conditions of plasma temperature and heat insulation have been largely achieved,suggesting that fusion energy for electric-power production is now a serious possibility.Commercial fusion reactors promise an inexhaustible source of electricity for countries worldwide.
