在核医学诊断中被誉为最先进显像设备的PET,是由PET扫描仪和生产短寿命同位素的医用小型回旋加速器配套组成。近年来中国国内对PET的需求迅速发展[1],为此,中国原子能科学研究院在10MeV强流回旋加速器综合试验装置调试达到430μA的基础上,设计、并开始建造引出能量为14MeV的强流紧凑型回旋加速器CYCIAE-14,计划第1台样机的建设周期为2年。一般的PET回旋加速器采用内部离子源,提供50～100μA的质子束流[2];CYCIAE-14采用基于外部负氢
Known as the most advanced imaging device in nuclear medicine, PET is composed of a PET scanner and a medical mini cyclotron that produces short-lived isotopes. In recent years, the domestic demand for PET in China has been rapidly developing [1]. Therefore, China Institute of Atomic Energy designed and started to construct a strong current with an energy of 14 MeV based on the commissioning of a 10 MeV high-current cyclotron integrated test device reaching 430 μA. CYCIAE-14 compact cyclotron, the first prototype of the construction period of 2 years plan. General PET cyclotron ion source with an internal 50 ~ 100μA proton beam [2]; CYCIAE-14 based on external negative hydrogen
