本文主要介绍“荧光-1”实验装置物理参数设计,并依据半经验公式预估在实验装置上可能达到的磁化等离子体状态参数.理论设计结果表明:“荧光-1”实验装置最大放电电流1.5MA,四分之一周期3μs,最大反向磁场4T;以此为实验平台,当θ箍缩线圈内充气压力50mTorr(D2气体)时,形成的等离子体靶直径约为2cm,长度17cm;等离子体靶密度6.6×1016cm-3,温度(Ti+Te)约300eV;等离子体平均β值为0.95.该状态参数接近磁化靶聚变所要求的等离子体靶初始状态参数.
In this paper, we mainly introduce the design of the physical parameters of “Fluorescence-1” experimental apparatus and estimate the possible magnetization plasma state parameters on the experimental apparatus according to the semi-empirical formula.The theoretical design results show that the “Fluorescence-1” experimental apparatus Maximum discharge current of 1.5MA, quarter-cycle of 3μs, the maximum reverse magnetic field of 4T; as the experimental platform, when the θ pinch coil pressure of 50mTorr (D2 gas), the formation of the plasma target diameter of about 2cm, Length of 17cm, plasma target density of 6.6 × 1016cm-3, temperature of (Ti + Te) of about 300eV and plasma average β of 0.95. The state parameter is close to the plasma target initial state parameter required by magnetization target fusion.
