Why is it important?
In inertial fusion energy (IFE) research based on inertial confinement fusion concept, a considerable attention has recently been focused on the issue of large target fabrication for MJ-class laser facilities. The ignition and high-gain target designs require a condensed uniform layer of hydrogen fuel on the inside of a spherical shell. In this report, we discuss the current status and further trends in the area of developing the layering techniques intended to produce ignition, and layering techniques proposed to high-rep-rate and mass production of IFE targets.
Perspectives
I am Professor, Dr. Sci. in Lebedev Physical Institute of Russian Academy of Sciences (LPI/RAS). Over the period of 1990 - 2017 I was the scientific leader of 10 Russian and international projects. As a result of this work our team created a unique technology of rapid free-standing target (FST) layering for continuous supply with a cryogenic hydrogen fuel of the ICF/IFE laser facilities. A fundamental difference of the FST layering method from generally accepted approaches is that it works with free-standing and line-moving targets, which allows one to economically fabricate large quantities of ICF/IFE targets and to continuously (or at a required rate) inject them at the laser focus. FST layering method is a promising candidate for development of FST-IFE transmission line at a high rep-rate capability intended for using in future power plants for process engineering. A careful consideration of this problem is currently underway at the LPI/RAS under Research Contract No. 20344 supported by the International Atomic Energy Agency (IAEA), and I am the Chief Scientific Investigator of this Research project.
