中国原子能科学研究院(CIAE)在20世纪90年代建造了一台30 MeV紧凑型强流质子回旋加速器后,经过近30年的发展,先后自主研发成功了基于剥离引出技术的能量为10 MeV、14 MeV、100 MeV、硼中子俘获治疗用14 MeV/1 mA等系列能量的紧凑型强流质子回旋加速器。建成的100 MeV紧凑型强流质子回旋加速器(CYCIAE-100),是目前国际上能量较高的一台紧凑型强流质子回旋加速器,最高流强达到520 μA,束流功率达到52 kW。建成的硼中子俘获治疗用的质子回旋加速器,也是我国首次自主研发成功的引出质子束流强达到mA量级的强流质子回旋加速器。在系列能量的紧凑型强流质子回旋加速器研发过程中,CIAE对剥离引出后的束流色散效应、剥离膜与束流夹角对引出后的束流品质的影响、单圈剥离引出技术等紧凑型强流质子回旋加速器剥离引出技术等方面展开了研究,且自主开发出了剥离引出计算程序,为紧凑型强流质子回旋加速器的应用作出了贡献。 相似文献

中国原子能科学研究院建成了一台强流质子回旋加速器,其引出能量为100 MeV,流强为200 μA。为减小粒子加速时束流损失的目的,其粒子加速腔内工作真空度要求为6.7×10-6 Pa。由于是紧凑型加速器结构,该加速器能提供给真空系统利用的通路有限,为此主真空系统设计为内置式低温冷板结合商业低温泵的排气方案以增加系统整体的抽气能力。设计、加工完成的真空系统已成功应用于100 MeV强流质子回旋加速器上,为加速器的束流调试和正常供束提供了有利的保障。 相似文献

A 14 MeV high intensity cyclotron CYCIAE-14 dedicated to Positron Emission Tomography (PET) is under construction at China Institute of Atomic Energy (CIAE). Based on a set of basic technical requirements for the accelerator and its extracted beam, the cyclotron beam dynamics were studied and the results are presented. Static beam dynamics, beam motion inside the machine under imperfection conditions and beam behavior in the extraction process were also investigated. This work gives an in-depth view of the beam dynamics study, numerical simulation as well as the corresponding results and necessary analyses. 相似文献

Based on a 10 MeV CRM cyclotron developed at China Institute of Atomic Energy (CIAE) with an achieved beam intensity of up to 430 μA, a 14 MeV high intensity compact cyclotron, CYCIAE-14, was designed and being built at CIAE. It is planned that the first machine would be in place with a span of 2 years. CYCIAE-14 is delicately designed to realize strong vertical focusing by adopting a 4-sector, variable hill-gap structure with an external ion source to achieve high intensity. A special design applied to the stripping extraction gives access to dual extraction with four beams. The adoption of sophisticated industrial technology will give the cyclotron advantages, e.g. low power consumption and high reliability. This paper is aimed to present the overall design of the machine, including the basic technical specifications, main magnet and coils, RF, ion source and axial injection, and stripping extraction, etc. It will also give an introduction to its construction schedule as well as the up-to-date progress. 相似文献

The cyclotron has an obvious advantage in offering high average current and beam power. Cyclotron development for various applications, e.g. radioactive ion-beam (RIB) generation, clean nuclear energy systems, medical diagnostics and isotope production, were performed at China Institute of Atomic Energy (CIAE) for over 50 years. At the moment two cyclotrons are being built at CIAE, the 100 MeV, CYCIAE-100, and a 14 MeV, the CYCIAE-14. Meanwhile, we are designing and proposing to build a number of cyclotrons with different energies, among them are the CYCIAE-70, the CYCIAE-800, and the upgrading of CYCIAE-CRM, which is going to increase its beam current to mA level. The contribution will present an overall introduction to the cyclotron development activities conducted at CIAE, with different emphasis to each project in order to demonstrate the design and construction highlights. 相似文献

This paper outlines the conceptual design work of a high power proton cyclotron proposed by the China Institute of Atomic Energy (CIAE) for a spallation neutron source, accelerator driven systems, production of radioactive ion beams, and other applications. For this cyclotron the 100 MeV injection proton beam is currently considered to be provided by the CYCIAE-100 cyclotron, which is under construction at CIAE and will be later replaced by a dedicated injector for beam upgrading. In order to minimize beam losses for high intensity operation, large turn separation at the extraction has first priority. After analyzing of different scenarios, including super conducting designs, a warm magnet solution was chosen. The conceptual design, field calculations, RF cavity simulations, etc. will be presented in the paper. 相似文献

This paper introduces the physics design of a 70 MeV high intensity cyclotron at China Institute of Atomic Energy (CIAE), which is aimed for multiple uses including radioactive ion-beam (RIB) production. The machine adopts a compact structure of four straight sectors, capable of accelerating two kinds of beams, i.e. H− and D− . The proton and deuteron beam will be extracted in dual opposite directions by charge exchange stripping devices. The energy of the extracted proton beam is in the range 35-70 MeV with an intensity up to 700 μA. The corresponding values for the deuteron beam are 18-33 MeV and 40 μA. This paper will present the main characteristics and parameters in the design of the 70 MeV cyclotron, the results of the basic beam dynamics study, as well as the physics in the design of the different systems, including the main magnet, RF, injection and extraction systems, etc. 相似文献
