| 1 | First mass measurement of short-lived nuclides at HIRFL-CSR显示文摘Recent commissioning of the HIRFL-CSR has demonstrated its ability to perform direct mass measurement for short-lived nuclides. Projectile fragments produced by the 78Kr ions at 481.88 MeV/u were separated with the new radioactive beam line in Lanzhou (RIBLL2), and injected into and stored in the experimental storage ring (CSRe). By operating the CSRe as an isochronous mass spectrometry, a typical mass resolution around 2.0×10?5 has been achieved. The masses for 63Ge, 65As and 67Se were measured for the first time. The measured masses are compared with theoretical predictions and the location of the proton drip-line for As isotopes is discussed. The implication of the 65As mass in the astrophysical rapid proton capture process has also been addressed. | XU HuShan TU XiaoLin YUAN YouJin XIA JiaWen ZANG YongDong WANG Meng MAO RuiShi HU ZhengGuo MEI Bo SHUAI Peng ZHU ZhiChao TANG ShuWen GENG Peng LIU Yong ZHAO TieCheng ZHANG XueYing YANG JianCheng MAO LiJun ZHANG YuHu ZHOU XiaoHong HUANG WenXue XIAO GuoQing ZHAO HongWei ZHAN WenLong | 2009 | Chinese Science Bulletin2009，54，24： | 11 |

| 4 | Distributed Stepping Motor Control System显示文摘The beam diagnostic devices used at RIBLL are driven by stepper motors, which are controlled by I/O modules based on ISA-bus in an industrial computer. The disadvantages of such mode are that a large number of long cables are used and one computer to control is unsafe. We have developed a distributed stepping motor control system for the remote, local and centralized control of the stepping motors. RS-485 bus is used for the connection between the remote control unit and the local control units.

| 5 | 4-2 Lifetime and the Ratio of 12C3+ and 16O4+ at the CSRe显示文摘Laser cooling is the most promising method to achieve high phase-space densities, even crystalline beams for relativistic heavy ion at storage rings[1]. A test laser cooling experiment has been performed with 12C3+ ions at the CSRe. In this experiment, the 12C3+ ions were produced from an electron cyclotron resonance (ECR) ion source, and due to the residual gas and the injection gases such as CO and CO2, 16O4+ ions will be produced at the same time. | Wang Hanbing Ma Xinwen Wen Weiqiang Huang Zhongkui Zhang Dacheng Hai Bang Chuai Xiaoya Zhao Dongmei Zhu Xiaolong Yang Jie Li Jie Mao Lijun Mao Ruishi Yang Jiancheng Yuan Youjin Zhao Hongwei Laser Cooling Collaboration | 2015 | IMP & HIRFL Annual Report2015，，1： | 0 |

| 7 | 2-4 First Isochronous Mass Measurement in Neutron-rich Region at CSRe显示文摘Mass is one of the fundamental properties of atomic nuclei. Isochronous mass spectrometry (IMS), using astorage ring combined with an in-flight separator, has been shown to be a powerful tool for mass measurementof exotic nuclei[1]. Recently, masses of many proton-rich nuclides were accurately determined at the HIRFL-CSRfacility[2]. In this paper, we described the first isochronous mass measurement of neutron-rich nuclides at CSRe.This experiment was performed at the end of 2011. In the experiment, the primary beam of 86Kr28+ ions wasaccumulated and accelerated to an energy of 460.65 MeV/u in the synchrotron CSRm. The 86Kr28+ ions were fastextracted and focused on a 15 mm thick beryllium target which was placed at the entrance of the RIBLL2 (anin-flight fragment separator). | Xu Xing Wang Meng Zhang Yuhu Xu Hushan Tu Xiaolin Yu.A.Litvinov Zhou Xiaohong Sun Baohua Yuan Youjin Xia Jiawen Yang Jiancheng K.Blaum Chen Ruijiu Chen Xiangchen Fu Chaoyi Ge Zhuang Hu Zhengguo Huang Wenjia Liu Dawei Y.H.Lam Ma Xinwen Mao Ruishi T.Uesaka Xiao Guoqing Xing Yuanming T.Yamaguchi Y.Yamaguchi Zeng Qi Yan Xinliang Zhao Hongwei Zhao Tiecheng Zhang Wei Zhan Wenlong | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |

However, themass-to-charge ratio (m=q) is only related to the revolution time (T) under the condition that is equal to taccording to the following equation: | Xing Yuanming Zhang Yuhu Wang Meng Xu Hushan Shuai Peng Xu Xing Chen Ruijiu Yan Xinliang Tu Xiaolin Zhang Wei Fu Chaoyi Zeng Qi Yu.A.Litvinov K.Blaum Chen Xiangcheng Ge Zhuang Gao Bingshui Huang Wenjia S.A.Litvinov Liu Dawei Ma Xinwen Mao Ruishi Xiao Guoqing Yang Jiancheng Yuan Youjin Zhou Xiaohong | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |

Since the isochronous condition =t greatly reducesthe influence of the velocity difference on the ion revolution periods, the revolution period difference ΔT =T ??TRof a stored ion with respect to a reference time TR is directly related to its mass-to-charge ratio difference Δ(m=q),written in the first order as: | Shuai Peng Xu Hushan Tu Xiaolin Zhang Yuhu Sun Baohua Yu.A.Litvinov Yan Xinliang K.Blaum Wang Meng Zhou Xiaohong He Jianjun Sun Yang K.Kaneko Yuan Youjin Xia Jiawen Yang Jiancheng G.Audi Chen Xiangcheng Jia Guobin Hu Zhengguo Ma Xinwen Mao Ruishi Mei Bo Sun Zhiyu Wang Shitao Xiao Guoqing Xu Xing T.Yamaguchi Y.Yamaguchi Zang Yongdong Zhao Hongwei Zhao Tiecheng Zhang Wei Zhan Wenlong | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |
