螺旋加速器采用脊型加速器的谐振加速腔。为了提高脊型极板内的束流孔道数量,我们提出了螺旋运动方式。脊型加速器采用蛇形加速方式,即电子的加速与传输在一个平面上,电子通过加速腔完成一次加速后,偏转180°重新注入加速腔,整个加速传输运动轨迹为往复型的。180°偏转需要较大的偏转空间,导致极板内排布的束 Helical accelerator uses the acceleration accelerator cavity of the ridge accelerator. In order to increase the number of beam channels in the ridge plate, we propose a spiral motion. The use of a serpentine acceleration of the ridge accelerator, that is, the acceleration and transmission of electrons in a plane, the electron acceleration through the acceleration chamber to complete an acceleration, the deflection of 180 ° re-injection into the acceleration chamber, the entire acceleration transmission trajectory for the reciprocating. 180 ° deflection requires a large deflection space, resulting in the arrangement of the beam within the plate
