| 1 | Sulfur-doped CMK-5 with expanded lattice for high-performance lithium ion batteries显示文摘Heteroatom-doped porous carbon materials are very attractive for lithium ion batteries(LIBs) owing to their high specific surface areas, open pore structures, and abundant active sites. However, heteroatomdoped porous carbon with very high surface area and large pore volume are highly desirable but still remain a big challenge. Herein, we reported a sulfur-doped mesoporous carbon(CMK-5-S) with nanotubes array structure, ultrahigh specific surface area(1390 m^(2)/g), large pore volume(1.8 cm^(3)/g), bimodal pore size distribution(2.9 and 4.6 nm), and high sulfur content(2.5 at%). The CMK-5-S used as an anode material for LIBs displays high specific capacity, excellent rate capability and highly cycling stability. The initial reversible specific capacity at 0.1 A/g is as high as 1580 mAh/g and simultaneously up to 701 mAh/g at 1A/g even after 500 cycles. Further analysis reveals that the excellent electrochemical storage performances is attributed to its unique structures as well as the expanded lattice by sulfur-doping. | Zhenjin Liang Yuhao Peng Xing Zhang Kewei Cao Wei Xiao Dong Gu | 2023 | Chinese Chemical Letters2023，34，7： | 0 |
| 2 | 6-34 Data Acquisition from Grating Ruler显示文摘Grating ruler is one of the most important devices in control system of micro beam. The faraday position must be acquired to con rm the beam position. How to acquire the position data accurately and quickly becomes signi cant grating ruler and DAQ board is made by an electronic company which is in Zhuhai. The interface of the board is RJ45 and the protocol is UDP. Grating Ruler and DAQ board is shown in Fig. 1. | Liu Xiaojun An Shi Gu Kewei Chang Jianjun Wang Pengpeng | 2015 | IMP & HIRFL Annual Report2015，，1： | 0 |
| 3 | 6-37 A Method for Implementing Feedback Control of CSRe Dipolar Magnet Power Supply显示文摘The magnetic field created by dipolar magnet is very important for the quality of beam in CSRe. It is required that the magnetic fields fluctuation ranges less than 0.3 10??4 T. Unfortunately, results show that the magnetic fields fluctuate more widely than limited. Reasons for the fluctuation are complex, transfer drift over temperature,zero shift, and output stability of power supply can all lead to magnetic field fluctuation. It is impossible to eliminate the effects of these factors. One way to solve the problem is to make current compensation. | Gu Kewei Yuan Youjin Zhang Wei Wang Pengpeng | 2015 | IMP & HIRFL Annual Report2015，，1： | 0 |
| 4 | 6-38 Redesign of IOC Based on a New Mode for Digital Power Supply at CSRe显示文摘The CSRe control system is based on EPICS. There are many sub systems such as power supply control system, vacuum monitor system, and so on. The structure of CSRe control system is shown in Fig. 1.Almost all of the power supply in the system uses digital power supply. So control interface between IOC and power supply is Ethernet interface. | An Shi Zhang Wei Gu Kewei Liu Xiaojun | 2015 | IMP & HIRFL Annual Report2015，，1： | 0 |
| 5 | 6-39 Motion Control for RIBLL1 Nuclear Astrophysics Experiment Terminal显示文摘The nuclear astrophysics experiments terminal of RIBLL1 (Radioactive Ion Beam Line in Lanzhou) is composed of two slide rails and a four-knife precision slit structure. Both of them are placed in a terminal chamber as shown in Fig. 1. During experiments, PPAC and experiment target are placed on two slide rails respectively. The width of four-knife slit is required to be adjusted during experiments. Also, in order to get results of different positions in chamber space, the position of PPAC and target must be able to be adjusted precisely in real time. | Chang Jianjun Zhang Wei Liu Xiaojun An Shi Gu Kewei | 2015 | IMP & HIRFL Annual Report2015，，1： | 0 |

| 8 | The inverse correlation between series resistance and parallel resistance of small molecule organic solar cells显示文摘Understanding the inversely correlated series resistance(Rs) and parallel resistance(Rp) remains a challenge. Here we report that the variation of Rs and Rp is inversely related through the morphology of the donor and acceptor interface in CuPc organic solar cells, when comparing the bilayer structure and bulk heterojunction structure. It was also found that the charge carrier concentration near the donor–acceptor interface plays an important role in the relationships of Rs and Rp under fixed interfacial morphology, which was verified by the change of Voc. The inversely correlated Rs and Rp contributes to the improvement of the fillfactor, and in turn the power conversion efficiency. | Kewei Wang Yufeng Zheng Gu Xu Xiuping Xu | 2015 | Progress in Natural Science:Materials International2015，25，4： | 0 |
| 9 | 5-28 Interlock of Vacuum Devices in SSC-Linac显示文摘The architecture of SSC-Linac vacuum control system is based on EPICS. The interlock of vacuum devices inSSC-Linac was introduced. We use C-RIO as an EPICS IOC to acquire data from vacuum gauges and controlvacuum valves. The software is programmed by Labview.The interlock of vacuum devices is very important for the whole system. If the pressure of the vacuum gauge islarger than the value we preset, the vacuum valve will be pushed in automatically and it can't be operated. If thepressure is smaller than the present value, we can operate the vacuum valve to be in or to be out[1]. | Liu Xiaojun Zhang Wei Gu Kewei An Shi Chang Jianjun Wang Pengpeng | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |
| 10 | 5-32 Network Communicating between IPC and Multimeter Based on LabView显示文摘The output stability of power supply for Heavy Ion Research Facility of Lanzhou (HIRFL) is signicant. Powersupply provides currents to magnets which produce the magnetic eld to constraint particles. So the output stabilityof power supply has a great signicance to the quality of beams. In order to test the stability of power supply, weuse a Fluke 8846A digit precision multimeter based on LabView platform of National Instrument Corporation.Remote operation of 8846A Digital Multimeter from a host, that is a terminal, controller, PC, or computer, isaccomplished by sending commands to it through one of its remote interfaces. The Multimeter is controlled remotelyusing Standard Commands for Programmable Instruments (SCPI), Fluke 45 or Fluke 8842A (8840A and 8842A)commands. The meter can be remotely controlled through the LAN port on the Meter's rear panel[1] We can sendSCPI commands to the Meter using network communicating controls provided by LabView[2]. This program couldbe used to test output stability of power supply of HIRFL. | Wang Pengpeng Zhang Wei An Shi Liu Xiaojun Gu Kewei Chang Jianjun Wu Junqi Chen Yun | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |
