Design of the Stripping Foil Exchanger for CYCIAE-100

作者： XIE Huai-dong AN Shi-zhong guan feng-ping

A 100 MeV H compact cyclotron(CYCIAE-100) is under construction at CIAE,and proton beams of 75-100 MeV will be extracted in dual opposite directions by charge exchange stripping *** stripping foil is one of the most important devices in the stripping extraction,and changing target is critical in all operations. In order to ensure the reliability,a test has been conducted for target changing before machining the whole device.A simple device is machined for the *** order to shorten the machining time and reduce the costs,the cooling and driving systems have been *** test has a good result,which indicates
