加速器驱动次临界核能系统(ADS)是下一代能源的首选方向。它能有效地利用铀和钍资源,嬗变长寿命高放射性废物和提高核安全水平。ADS加速器应能提供几十兆瓦质子束。超导直线加速器(SCL)效率高,束流损失少,是ADS加速器的最佳选择。它由一系列超导加速腔组成。利用电磁场计算确定腔的形状,利用粒子动力学计算确定SCL的主要参数。
Accelerator-driven subcritical nuclear energy system (ADS) is the preferred direction for the next generation of energy. It can effectively utilize uranium and thorium resources, transmute long-lived high-level radioactive waste and improve nuclear safety. The ADS accelerator should be capable of delivering tens of megawatts of proton beams. Superconducting linear accelerator (SCL) high efficiency, less beam loss, is the best choice for ADS accelerator. It consists of a series of superconducting accelerating cavities. The shape of cavity was determined by electromagnetic field calculation, and the main parameters of SCL were determined by particle dynamics calculation.
