There is no alternative choice for a large capacity energy source other than the fusion energy. This fact warrants us to continue refining the understanding of the high temperature plasma physics. Even though a significant empirical understanding led us the construction of the International Thermonuclear Experimental Reactor (ITER) at Cadarache, France, which will demonstrate the engineering viability of the fusion energy, the basis of ITER performance is on empirical scaling laws instead of first principle based physics. This may have to do with the fact that the physics of high temperature plasmas is still in an infant stage and is substantially more complex compared with other branches of physics. The new superconducting magnetic confinement devices (KSTAR of Korea, EAST of China and LHD of Japan) in Asia ignite the research on t he steady state plasma operation that once was craved by the US/EU. At the same time, powerful new 2-D/3-D imaging diagnostic tools that can validate and verify the established high temperature plasma physics, have been recently developed. The new generation superconducting fusion devices equipped with the advanced imaging tools will advance the first principle based physics necessary in designing a viable compact future fusion energy device.
