Fabrication progress and key technologies of Be targets

The nuclear fusion reaction is an ideal approach to solve the shortage of energy and produce sustainable clean energy. The National Ignition Facility device has been built in the United States in order to demonstrate the nuclear fusion reaction. It can provide a clear development direction for the inertial fusion energy. Fabricating target is one of the three main bodies for NIF. How to fabricate an ignition target to meet design requirements becomes tireless efforts of scientists to pursue goals. The objective of this paper is to introduce the requirement background of candidate Be target, research status, advantages of Be target, design specifications, preparation technology, as well as some key technical issues existed in fabrication process. It will provide an useful reference information for the target fabrication science in our country, and lay a foundation for the ability building of target fabrication.
