CF-Ⅱ等离子体环加热和注入实验,是利用场反向θ-箍缩所产生的等离子体环,通过物理变化导致等离子体环进行轴向激波加热向约束区传输,注入到磁镜系统中约束,以达到延长等离子体环的约束时间。在形成区产生的等离子体环的参数是:环半径R约为4cm,拉长度L约为40cm,电子密度n_e=10~(15)cm~(-3),电子温度T_c=20eV,约束时间τ约为30μs。等离子体环以7.8×10~6cm/s的速度从形成区向约束区传输,加热后的电子温度大约为34eV。 CF-II plasma ring heating and injection experiments, the use of field reverse θ-pinch plasma ring generated by the physical changes caused by the plasma ring axial shock heating transmission to the constraint area, injected into the magnetic mirror system In order to extend the confinement time of the plasma ring. The parameters of the plasma ring generated in the forming zone are as follows: the radius R of the ring is about 4 cm, the drawing length L is about 40 cm, the electron density n_e is 10-15 cm -3, the electron temperature T_c is 20 eV, τ is about 30μs. The plasma ring is transported from the formation zone to the confinement zone at a velocity of 7.8 × 10 -6 cm / s, and the electron temperature after heating is about 34 eV.
