100 MeV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75~100 MeV的质子束。剥离引出系统采用双内杆对称剥离引出方式,可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。按照束流引出的要求,剥离靶采用在磁间隙区域径向插入方式。为保证在不同束流轨道上剥离后的不同能量的离子束,最终都能够到达引出开关磁铁的中心,因此剥离靶需要在径向能够移动,在辐角方向能够转动,而且对于剥离靶的运动定位也有较高的精度要求。
The 100 MeV high-flow negative-ion cyclotron uses a peel-off method to extract a proton beam with an energy of 75-100 MeV. Peeling off the system using double-rod symmetrical peel-off mode, respectively, in both directions symmetrical leads to the beam. Stripping targets are the most critical and complex devices in the stripping system. In accordance with the requirements of beam extraction, stripping target used in the magnetic gap region radial insertion. In order to ensure that ion beams of different energy stripped on different beam orbits can finally reach the center of the lead-out switching magnet, the stripping target needs to be able to move in the radial direction and rotate in the radial direction, and for the stripping target Positioning also has higher accuracy requirements.
