| 1 | 6-4 Development of a Slow Tuner for the 162.5 MHz Superconducting Half-wave Resonator in IMP显示文摘China-ADS project, a continuous wave (CW) proton accelerator and aims to design and build an ADS demonstration facility has been proposed and launched actively in China. HWR ( =0.10) superconducting cavity with frequency of 162.5 MHz is applied to one of the parallel injectors prompted by Institute of Modern Physics (IMP)[1]. | Liu Lubei Zhang Bin He Yuan Zhang Shenghu Wang Ruoxu | 2015 | IMP & HIRFL Annual Report2015,,1: | 0 |
| 2 | 6-7 Dual-windows Coupler R&D in IMP显示文摘IMP hosts the project of high intensity Heavy Ion Accelerator Facility (HIAF). High power input couplers are needed for the SRF cavities. In order to assemble cryo-module easily and run the machine safely, new TTF-III like demountable dual-ceramic coupler is developed. This paper will present some results of the 162.5 MHz coupler for the tapper HWR cavity. | Li Yongming Wang Ruoxu Zhang Shenghu Jiang Tiancai Sun Guozhen Liu Lubei He Yuan Zhao Hongwei | 2015 | IMP & HIRFL Annual Report2015,,1: | 0 |
| 3 | ADS25 MeV直线加速器直线段调谐器测试显示文摘The tuner system of ADS 25 MeV Linac(Fig.1)built in CM1,CM2 and CM3 consists of 17 tuners and every tuner consists of two parts-linear drive unit and tuning implement unit.Linear drive unit is mainly composed of step motor,reduction box,screw-nut and coupler(Fig.2).To learn about the working conditions and structure characteristics,17 tuners were tested and the CM1-2,CM2-3 and CM3-1 were chosen as representatives to give a brief introduction of test procedure and results. | Zhang Lei Wang Fengfeng Liu Lubei Gao Zheng Zhang Bin | 2017 | IMP & HIRFL Annual Report2017,,1: | 0 |
| 4 | 650 MHz Elliptical Cavities Development in IMP for CiADS显示文摘Multicell superconducting radio frequency(SRF)elliptical cavities are proposed for efficient acceleration of proton beam in the Chinese initiative Accelerator Driven Subcritical System(CiADS). | Huang Yulu Wang Ruoxu Liu Lubei Jiang Tiancai Zhang Shengxue Liu Shuhui Tan Teng Guo Hao Li Chunlong Yue Weiming Zhang Zhouli Wang Zhijun Zhang Shenghu He Yuan | 2019 | IMP & HIRFL Annual Report2019,,1: | 0 |
| 5 | 6-5 Operation of HWRs for C-ADS Injector显示文摘There are two types of HWR cavities have been developed in IMP for C-ADS Injector.HWR010s have been used to accelerate proton from 2.1 MeV to 10 MeV.There are 12 HWR010s assembled in two CMs.The taper type HWR015s have been used to accelerate proton from 10MeV to 18.5 MeV.There are 5 HWRs assembled in the third CM.Proton beam has been accelerated to 26 MeV by HWR010,HWR015 and Spoke021 in June 2017.The beam has been accelerated to 18.5 MeV by HWR010 and HWR015.The CMs in the tunnel are shown in Fig.1. | Yue Weiming Zhang Shenghu Li Yongming Chang Wei Jiang Tiancai Zhang Shengxue Gao Zheng Wang Ruoxue Huang Shichun Pan Feng Chen Long Li Chunlong Song Yukun Guo Hao Xiong Pingran Cong Zhang Tan Teng Wan Yuqin Niu Xiaofei Bai Feng Hu Chuanfei Zhang Peng Liu Lubei Huang Yulu Zhao Yugang Guo Xiaohong You Zhiming Zhang Junhui Huang Guirong He Yuan | 2016 | IMP & HIRFL Annual Report2016,,1: | 0 |
| 6 | 6-11 SRF Power Input Coupler for HWR010 at IMP显示文摘The high power superconducting radiofrequency(SRF)input coupler is the connecting part between the SRF cavity and the RF transmission line.With the RF power transferred through the coupler,the SRF cavity can built up the electromagnetic field and then accelerate the beams.In addition to this RF transmission function,it also has to serve as a vacuum barrier for the SRF cavity vacuum.The HWR010 coupler which designed by IHEP is a single ceramic window coupler. | Li Yongming Jiang Tiancai Wang Ruoxu Zhang Shenghu Yue Weiming Xiong Pingran Li Chunlong Liu Lubei Zhang Shengxue Song Yukun He Yuan | 2016 | IMP & HIRFL Annual Report2016,,1: | 0 |
| 7 | 6-12 Design of a Double Spoke Cavity for CADS显示文摘Spoke cavities have been developed and have apparent advantages for high current proton accelerator based on Fig.1(color online)The electromagnetic field distribution.superconductivity at low and medium energy region.As the research and the technical reserve,Institute of Modern Physics(IMP)has started the R&D program of a double spoke cavity(operating frequency 325 MHz,0=0.52),within the framework of China Accelerator Driven System(C-ADS)project.The RF design and mechanical structure design have been finished,and two prototype cavities were manufactured in Harbin. | Jiang Tiancai Zhang Shenghu Li Yongming Yue Weiming Xiong Pingran Li Chunlong Liu Lubei Zhang Shengxue Wang Ruoxu Song Yukun Guo Hao Huang Yulu You Zhiming He Yuan | 2016 | IMP & HIRFL Annual Report2016,,1: | 0 |
