洁净核能系统的强流连续波质子直线加速器常温腔方案中 ,高能段采用边耦合加速结构(CCL) ,频率为 70 0MHz ,工作模式为π/2模。CCL把来自耦合腔漂移管加速器 (CCDTL)的30mA、80MeV的质子束加速到 1GeV。CCL段总长 1 0 6 4m ,采用FODO的横向聚焦结构 ,聚焦周期长度为 8βλ。腔的束孔道半径为 2 0 0、2 2 5、2 5 0cm。用SUPERFISH优化腔 ,给出了计算结果 ,同时给出了能量增益等计算结果 In the high-current continuous-wave proton linac chamber program of a clean nuclear power system, the high-energy section adopts an edge-coupled accelerating structure (CCL) with a frequency of 70 0 MHz and a working mode of π / 2 mode. The CCL accelerates a 30 mA, 80 MeV proton beam from a Coupling Cavity Drift Tube Accelerator (CCDTL) to 1 GeV. The total length of the CCL section is 1 0 6 4m. The horizontal focusing structure of FODO is adopted, and the focusing period length is 8βλ. The cavity beam path radius is 200, 225, 2550 cm. With SUPERFISH optimization chamber, given the calculation results, given the energy gain calculation results
