In-Line Target Production for Laser IFE

An Active Feedback Target Engagement System for Laser-IFE

Grazing-Incidence Metal Mirrors for Laser-IFE

Development of Target Injection and Tracking for IFE in Japan

The study of target injection, detection, measurement of laser focal point, and laser beam steering have started under co-research in Japan. The smooth-bore gas gun is developed for accurate injection. The applications of divergent laser beam and Arago spot are described for accurate measurement of target position and laser focal point. Magnetic lens for target trajectory adjustment by centerin...

Review on high repetition rate and mass production of the cryogenic targets for laser IFE

In inertial fusion energy (IFE) research, 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...

Thermomechanical Effects in a Laser IFE First Wall

Laser fusion chamber walls will experience large, pulsed heat loads at frequencies of several hertz. The heating, consisting of x-rays, neutrons, and ions, occurs over a few microseconds and is deposited volumetrically over the first few microns of the wall. For a reasonable chamber radius, the heating will be such that the surface temperature is a significant fraction of the melt temperature o...
