| MOAI01 | Status of the HIAF Accelerator Facility in China | 1 |
|
||
| HIAF (High Intensity heavy ion Accelerator Facility) is a new accelerator facility for advances in the nuclear physics and related research fields in China. It is composed of a superconducting ion linear accelerator, a high-energy synchrotron booster, a high-energy radioactive isotope beam line, an experimental storage ring, and a few experimental setups. Characterized by unprecedented intense ion beams from hydrogen through uranium, HIAF can produce a large variety of exotic nuclear matters not normally found on the earth and will bring researchers to the forefront of promoting the most vigorous and fascinating fields in nuclear physics. In addition, HIAF will provide an excellent platform to develop heavy-ion applications in medicine, life science, space science, and material science. The construction of HIAF started up in December of 2018, and takes approximately seven years in total. Since the commencement, the civil engineering and infrastructure are being constructed on time schedule and will be completed in July, 2023. R&D on key accelerator techniques are going on successfully, and prototypes of core devices are fabricated in collaboration with home and abroad universities, institutes, and companies. Presently, we come to the stage of invitation for bids and volume production of various apparatuses. The progress and present status will be given in the presentation. | ||

| WEPO016 | A New 18 GHz ECR Ion Source for Cyclotron at CIAE | 234 |
|
||
| In order to meet the requirements of ion beam for the single event effect experiment, the ion source needs to supply ion beams of N, Ne, Si, Ar, Fe, Kr, Xe, and so on for the cyclotron. The most effective way to increase the energy of the cyclotron is to increase the charged state, and the Kr ion charge state reaches +22 while the Xe ion charge state reaches +35. A new room-temperature Electron Cyclotron Resonance (ECR) ion source operating at 18 GHz has been developed and assembled at CIAE. This new ECR ion source is based on the Lanzhou Electron Cyclotron Resonance ion source No.5 (LECR5) developed at IMP. The magnetic confinement of the new ECR ion source is realized by the axial mirror field provided by two set of room temperature pancake coils while the radial hexapole field is supplied by a permanent magnet hexapole. A multi-sputter disk injection component was designed for the production of metallic cocktail ion beams. This paper will give the detailed design of this ion source, and some preliminary highly charged ion beam production results will also be presented. | ||

| THBI02 | Status Report on the Cyclotron Injector for HIMM | 269 |
|
||
| HIMM (Heavy Ion Medical Machine) is an accelerator complex designed by Institute of Modern Physics, CAS, which accelerates carbon ions to the energy 400 MeV/A for tumor therapy. The main accelerator of HIMM is a synchronous accelerator. As a special design, we use a cyclotron as the injector of the synchrontron. The cyclotron is a compact cyclotron to accelerate C125+ ions to the energy 6.8 MeV/A, and the extracted beam intensity of the cyclotron is 10 eµA. For stability and simplicity operation, we use two identical permanent magnet ECR ion sources in the axial injection line, that the ion sources can interchange with each other rapidly with the same performance, and only one main exciting coil with no trim coils in the cyclotron magnet. Up to now, three cyclotrons have been accomplished, one of them was operated in Gansu Wuwei Tumor Hospital to treat more than six hundred cancer patients in the last two and a half years, the other one had been fully commissioned in Lanzhou Heavy Ion Hospital about two years ago. After a short introduction to the heavy ion cancer treatment facility development in China, this paper will present operation status of the cyclotrons for HIMM. Typical performance and on-line operation reliability will be discussed. | ||

Simulation Study of Inflector for High Intensity Ion Beam Injection | |
|
||
| Compact cyclotron for isotope production has received wide attention around the world, especially those of high beam intensity. When ion beam enters the cyclotron acceleration system, it needs to pass through the spiral inflector in the axial injection system to deflect the beam by 90° to make it reach the acceleration plane. However, the space charge effect and beam loss that occur in the high-current compact cyclotron make the design of the spiral inflector a big challenge. We used CST and COMSOL to simulate the injection of H2+ particles with an energy of 80 keV into a compact cyclotron from RFQ. Python was used to calculate the spiral inflector model data, and the VBA module of CST was used to establish the 3D mirror model. This will provide a reliable solution for the design and optimization of high-current compact cyclotron. | ||
