串列加速器升级工程正在研制的100MeV强流负氢离子回旋加速器采用剥离引出的方式引出能量为75～100MeV的强流质子束。剥离引出系统采用双内杆对称剥离引出方式,可以在对称两个方向分别引出束流。剥离靶为剥离引出系统中最为关键和复杂的设备。按照剥离引出的要求,剥离靶采用在磁间隙区域径向伸入方式。为保证在不同束流轨道上剥离后的不同能量的离子束,最终都能够到达开关磁铁的中心,因此剥离靶需要在径向可以移动,在辐角方向可以转动,而且对于剥离靶的运动定位也有较高的精度要求。剥离靶的设计,一方面要满足剥离引出的要求,另一方面,
Tandem accelerator upgrade project under development 100MeV strong current negative ion cyclotron leads to the use of stripping leads to the energy of 75 ~ 100MeV strong stream proton beam. Peeling off the system uses double-pole symmetrical stripping leads, can be in the symmetry of the two directions leads to the beam. Stripping targets are the most critical and complex devices in the stripping system. In accordance with the requirements of stripping leads, the stripping target adopts a radial extending manner in the magnetic gap region. In order to ensure that ion beams of different energy stripped on different beam orbits can finally reach the center of the switching magnet, the stripping target needs to be movable in the radial direction, rotatable in the radial direction, and positioned to peel off the movement of the target There are also higher accuracy requirements. Peeling target design, on the one hand to meet the requirements of stripping lead, on the other hand,
