摘要
分析了柱腔充气靶动态充气、准动态充气和静态充气3种充气方式的特点,完成了无源充气靶的设计和制备,测量了无源充气靶的保气半寿命,讨论了靶的储存和运输。研究表明:充Kr的玻璃柱腔充气靶保气半寿命不低于341 h,以打靶时间为3 h计算,靶内气体泄漏率不超过2%;采用高压保气罐对成品进行储存和运输,无源柱腔充气靶可实现异地打靶。
The gas-filled hohlraum targets is one of the most important targets in the inertial confinement fusion experiments. There are three ways to fill the hohlraum with necessary gases: filling gas at the same time of or before the shot, or before the experiment. This paper focused on the fabrication of gas-filled targets without gas source. Based on the design of the targets assembly, a seris of gas-filled targets were finished, whose hohlraum materials were Au, plastic and glass. Experiments show that the half life time of the target is no less than 341 hours for Kr-filled glass hohlraum, and the amount of leaded gas is no more than 2% of the total gas in the target within 3 h. Remote-place shooting could be realized by keeping the finished target in a high pressure gas-retention tank during transportation.
