摘　　要：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 。In the normal conductive project of high beam in density proton linac in accelerator driven energy system, the high energy section uses side coupled cavity linac(CCL)structure,its frequency is 700 MHz, and operates on π/2 mode. CCL section accelerates the 30 mA, 80 MeV proton beam from the coupled cavity drift tube linac(CCDTL) to 1 GeV. The total length of CCL is 1 064 m, the focusing lattice is FODO, the focusing period is 8βλ. Bore radii of the cavities are 2.00, 2.25 and 2.50 cm, respectively. The cavities are optimized with SUPERFISH code. The calculation results of the cavities and energy gain are presented.
