ECR离子源作为最主要的注入器，为重离子加速器提供强流高电荷态难熔金属离子束的需求日益增加。这要求对ECR离子源的性能进一步提高，使金属高温炉能够在超高温度下长时间稳定工作。感应高温炉采用高频加热，克服了传统电阻型高温炉因受洛伦兹力而变形的问题，能够在ECR离子源强磁场环境下稳定工作。本申请项目将在完成新型感应高温炉结构设计的基础上，重点研究交变磁场产生涡流的有效利用与限制、热传导与热辐射的有效屏蔽以及坩埚表面的喷涂工艺等问题。最后将完成感应高温炉的原型制造，并在近代物理研究所的高温炉测试平台上进行实验验证，根据反馈信息，最终设计出一款工作温度达到2000℃以上，寿命达到或超过1000小时的感应高温炉。

As the main injector of heavy ion accelerator, ECR ion source needs to provide more and more intense highly charged refractory metallic ion beams. This requires the performance of ECR ion source to be further improved so that the metallic oven can work for a long time at ultra-high temperature. Compared with traditional resistive oven, the induction oven is designed to use high-frequency heating to overcome the problem of deformation caused by Lorentz force. It can work normally in an ECR ion source under the strong magnetic field. Based on the completion of new induction oven structure design, this project will focus on the effective utilization and restriction of eddy effect, the effective shielding of heat conduction and thermal radiation, and the surface coating on the crucible. Finally, the prototype of induction oven will be fabricated, and it will be tested on the offline test platform at Institute of Modern Physics. According to the results, a high-temperature induction oven with working temperature over 2000 degrees C and life more than 1000 hours will be designed and fabricated.
