对提高超导直线加速器(SLA)中芯块容器的可达速度进行了数值研究。为此,已经开发了一个数值程序,用于分析高温超导薄膜中的屏蔽电流密度。此外,另一个线圈被放置在常规线圈的外侧。计算结果表明,SLA系统的加速时间为2.1 s,与仅使用常规线圈相比,该时间缩短了5.7 s。此外,还发现电磁轨道的距离与以前研究的数值结果相比减少到1/3或更少。但是,我们发现即使是这个值也太长了。我们的结论是,有必要使轨道的形状不是直的,而是圆形的。此外,我们的研究还需要在圆形电磁轨道的形状进行讨论。
Improvement of the achievable speed of the pellet container in the superconducting linear acceleration (SLA) system has been investigated numerically. To this end, a numerical code has been developed for analyzing the shielding current density in a high-temperature superconducting film. Moreover, another coil is placed on the outside of the conventional one. The results of computations show that the acceleration time of the SLA system is 2.1 s, and this time becomes shorter 5.7 s as compared to the only use of the conventional coil. In addition, it is found that the distance of electromagnetic rails is reduced to 1/3 or less compared with the numerical results of the previous study. However, we found that even this value is too long. We conclude that it is necessary to make the shape of the rail not straight but circular. Furthermore, our study also needs to be discussed in the circular shape of electromagnetic rails.
