The dynamic stability in CVD Nb3Sn superconducting tapes has been studied both theoretically and experimentally. In consideration of a twodimensional model, the stability criterion has been found to bewhere ηis the volume fraction of the superconductor, ω is a parameter eharacteriging the superconducting tape geometry and the cooling condition. Using the above criterion, we show that there exists a optimum copper-clad thickness, which have maximum of the overall critical current density. This thickness is determined by expressionwhere ξ is the ratio of the thickness of the matrix to that of the superconductor. We have discussed the effects of the conductor geometry, thickness of copper-clothing dcu, condition of cooling, applied magnetic field and transport current on the stability. With dcu reaching a certain value, a transition is made from dynamic stability to cryostatic stability. The theory is in good agreement with the results of the experiments by using simulation coils.

A 2-D CEBQ code in cylindrical geometry and a ENVLOP code used to simulate the emission and transport of intense relativistic electron beams in LIA are described in this paper. The CEBQ code simulates all electron trajectories in a diode considering effects of space charge and external electric and magnetic field. Poisson equation is solved with the finite element method suitable to complex boundary and clouds in-cell method is used to calculate charge deposition. The problem of β> 1 in numerical simulation is better overcome by using the conservation of canonical angular momentum. Two techniques are employed to improve numerical instability and to steep up the convergence of iteration: subrelaxation iteration for charge density and pervence.

我们研制了CEBQ程序和ENVLOP程序,模拟稳态相对论电子束在二极管区的产生和加速,以及电子束在阳极通道内的传输过程。CEBQ程序模拟二极管区电子轨道,当阳极电压为1.5MV时,阴极总发射电流为17.9kA,进入阳极通道内的传输电流为4.3kA,阳极入口处D=4cm的束发射度为24.9cm.mrad。ENVLOP程序使用线性近似下的包络方程,描述电子束包络在螺旋管引导磁场作用下的变化,讨论了外加引导磁场对包络的影响。计算结果表明,在合适引导磁场作用下,束包络起伏较小,进入阳极通道的束流(4.3kA)能全部通过。
