摘要：In a cyclotron,the rf cavity is the key device to accelerate *** rf cavity design for the 100MeV H^- cyclotron is very complex since the space is narrow and the Dee voltage is 60kV at the center and 120kV at the extraction *** MICROWAVE STUDIO is used in the design,and a real model has been *** test result on the model is in good agreement with the simulation result.

摘要：The tolerances of the manufacture and installation errors and Dees deformation caused by gravity in rf cavity of CYCIAE-100 are *** the analytic treatment and numerical simulation are carried out to give the tolerance of the manufacture and installation errors which disturb the radial and vertical motion of the *** Dees deformation caused by gravity leads to axial misalignment of the Dees and then induces the build-up of coherent axial ***,the calculated results show that the deformation of our Dees is acceptable.

摘要：A new RIB project, the Beijing Radioactive Ion-beam Facility （BRIF）, has been running at CIAE since 2004. In this project, a 100 MeV H-cyclotron, CYCIAE-100, is selected as the driving accelerator providing a 75-100 MeV, 200-500 μA proton beam. An ISOL system employs two stage separators to reach the mass resolution of 20000. Its RIB beam will be injected into the existing Tandem and a superconducting booster installed down stream of the Tandem will increase the energy by 2 MeV/q. The progress of BRIF, giving special emphasis to CYCIAE-100, will be introduced in this paper.

摘要：The design and construction of Beijing Radioactive Ion-beam Facility (BRIF) was started at China Institute of Atomic Energy -CIAE) in 2004. In this project, a 100 MeV high intensity cyclotron, CYCIAE100, is selected as a driving accelerator for radioactive ion beam production. It will provide a proton beam of 75—100 MeV with an intensity of 200—500 μA. The scheme adopted in this design, i.e., stripping the accelerated H-, makes the structure more compact and construction cost much lower. At present, the design for each system has been accomplished. This paper depicts the basic physics design of the machine, including its major structure and parameters, beam dynamics and each relevant system, e.g. basic structure of the main magnet, numerical simulation of the rf resonant cavity, axial injection system, central region, and study on crucial physics problems concerning the extraction and beam lines. The major problems encountered during the design of CYCIAE-100 are also summarized in this paper.
