| 1 | Development and Preliminary Commissioning Results of a Long Pulse 140 GHz ECRH System on EAST Tokamak(Invited)显示文摘A long pulse electron cyclotron resonance heating(ECRH)system has been developed to meet the requirements of steady-state operation for the EAST superconducting tokamak,and the first EC wave was successfully injected into plasma during the 2015 spring campaign.The system is mainly composed of four 140 GHz gyrotron systems,4 ITER-Like transmission lines,4 independent channel launchers and corresponding power supplies,a water cooling,control &inter-lock system etc.Each gyrotron is expected to deliver a maximum power of 1 MW and be operated at 100-1000 s pulse lengths.The No.1 and No.2 gyrotron systems have been installed.In the initial commissioning,a series of parameters of 1 MW 1 s,900 k W 10 s,800 k W 95 s and650 k W 753 s have been demonstrated successfully on the No.1 gyrotron system based on calorimetric dummy load measurements.Significant plasma heating and MHD instability suppression effects were observed in EAST experiments.In addition,high confinement(H-mode)discharges triggered by ECRH were obtained. | 徐旵东 王晓洁 刘甫坤 张健 黄懿赟 单家方 吴大俊 胡怀传 李波 李妙辉 杨永 冯建强 徐伟业 汤允迎 韦维 徐立清 刘永 赵海林 J.LOHR Y.A.GORELOV J.P.ANDERSON 马文东 吴则革 王健 张立元 郭斐 孙浩章 闫新胜 EAST Team | 2016 | Plasma Science and Technology2016，18，4： | 6 |
| 2 | Measurement of molybdenum ion density for L-mode and H-mode plasma discharges in the EAST tokamak显示文摘We report the measurement of total molybdenum ion density for L-mode and H-mode plasmas on EAST using spectral lines observation and calculation based on an impurity transport code.A flat-filed extreme ultraviolet spectrometer with some spatial resolution is used to obtain the radial profiles of molybdenum spectral line emissions.The absolute calibration for the extreme ultraviolet spectrometer is finished by comparing the calculated bremsstrahlung intensity with the readings of CCD detector.Molybdenum ion transport study is performed using the radial ion density profiles and one-dimensional impurity transport code STRAHL.The total molybdenum density profiles are determined from the transport analysis.The molybdenum density during L-mode and H-mode phases are obtained,which are about 3 and 4 orders of magnitude smaller than the electron density,respectively.An inward pinch is found during the H-mode phase that leads to the peaked profile of molybdenum density. | 沈永才 张洪明 吕波 李颖颖 符佳 王福地 臧庆 万宝年 潘盼 叶民友 the EAST team | 2020 | Chinese Physics B2020，29，6： | 2 |
| 3 | Observation and characterization of the effect of electron cyclotron waves on toroidal rotation in EAST L-mode discharges显示文摘The change in the toroidal rotation of plasma caused by electron cyclotron wave(ECW) injection has been observed in EAST. It is found that the response of the rotation is similar for all possible ECW toroidal injection angles. The core toroidal rotation velocity increases in the co-current direction along with a rise in the plasma temperature and stored energy. The profile of the electron temperature, ion temperature and toroidal rotation velocity gradually become peaked.The change in toroidal rotation in the core increases with the ECW injection power. Different behavior is observed when the ECWs are injected into low hybrid current drive(LHCD) target plasmas, where the electron temperature and rotation profile become peaked, while the ion temperature profile flattens after ECW injection, suggesting different transport characteristics in energy and momentum. | 陈俊 胡睿佶 吕波 王福地 王晓洁 徐旵东 李颖颖 符佳 尹相辉 吴大俊 刘甫坤 臧庆 刘海庆 石跃江 毛世峰 余羿 万宝年 叶民友 沈永才 EAST team | 2017 | Plasma Science and Technology2017，19，10： | 2 |
| 4 | Density Profile and Fluctuation Measurements by Microwave Reflectometry on EAST显示文摘A microwave reflectometry system operating in the V-band frequency with extraordinary mode polarization has been developed on the EAST tokamak.The reflectometry system,using a voltage-controlled oscillator(VCO) source driven by an arbitrary waveform generator with high temporal resolution,can operate for the density profile measurement.The result of the bench test shows that the output frequency of the VCO has a linear dependence on time.The dispersion of reflectometry system is determined and reported in this paper.The evolution of a pedestal density profile during the L-H transition is observed by the reflectometry in H-mode discharges on EAST tokamak.A frequency synthesizer is used to replace the VCO as microwave source for density fluctuation measurements.The level of density fluctuation in the pedestal shows an abrupt decrease when the plasma enters into H-mode.A coherent mode with a frequency of about100 kHz is observed and the mode frequency decreases gradually as the pedestal evolves. | 张寿彪 高翔 凌必利 王嵎民 张涛 韩翔 刘子奚 布景亮 李建刚 EAST team | 2014 | Plasma Science and Technology2014，16，4： | 2 |

| 9 | Long Pulse H-Mode Scenarios Sustained by RF Heating on EAST显示文摘EAST has demonstrated its capability of long pulse operation using RF heating(LHCD and ICRF)in past experiments.One key issue to realize the long pulse H-mode experiments is to sustain the plasma current for steady state operation.Based on the calculations of the transport code ONETWO and its coupled RF code GENRAY,two scenarios have been proposed to achieve the 10 s H-mode plasma with Ip=400 kA, | 高翔 李国强 张涛 杨曜 龚先祖 刘子奚 任启龙 刘海庆 曾龙 余耀伟 刘少承 刘晓菊 张寿彪 蔡辉山 吴雪梅 李建刚 the EAST team | 2015 | Plasma Science and Technology2015，17，6： | 1 |

| 11 | The Calibration of High-Speed Camera Imaging System for ELMs Observation on EAST Tokamak显示文摘A tangential fast visible camera has been set up in EAST tokamak for the study of edge MHD instabilities such as ELM.To determine the 3-D information from CCD images,Tsai's two-stage technique was utilized to calibrate the high-speed camera imaging system for ELM study.By applying tiles of the passive stabilizers in the tokamak device as the calibration pattern,transformation parameters for transforming from a 3-D world coordinate system to a 2-D image coordinate system were obtained,including the rotation matrix,the translation vector,the focal length and the lens distortion.The calibration errors were estimated and the results indicate the reliability of the method used for the camera imaging system.Through the calibration,some information about ELM filaments,such as positions and velocities were obtained from images of H-mode CCD videos. | 付超 钟方川 胡立群 杨建华 仰振东 甘开福 张斌 EAST Team | 2016 | Plasma Science and Technology2016，18，9： | 1 |

| 14 | Preliminary results of in situ laser-induced breakdown spectroscopy for the first wall diagnostics on EAST显示文摘Post-mortem methods cannot fulfill the requirement of monitoring the lifetime of the plasma facing components(PFC) and measuring the tritium inventory for the safety evaluation.Laserinduced breakdown spectroscopy(LIBS) is proposed as a promising method for the in situ study of fuel retention and impurity deposition in a tokamak.In this study,an in situ LIBS system was successfully established on EAST to investigate fuel retention and impurity deposition on the first wall without the need of removal tiles between plasma discharges.Spectral lines of D,H and impurities(Mo,Li,Si,...) in laser-induced plasma were observed and identified within the wavelength range of 500-700 nm.Qualitative measurements such as thickness of the deposition layers,element depth profile and fuel retention on the wall are obtained by means of in situ LIBS.The results demonstrated the potential applications of LIBS for in situ characterization of fuel retention and co-deposition on the first wall of EAST. | 胡振华 李聪 肖青梅 刘平 丁芳 毛红敏 吴婧 赵栋烨 丁洪斌 罗广南 EAST team | 2017 | Plasma Science and Technology2017，19，2： | 1 |

| 19 | Synchrotron radiation intensity and energy of runaway electrons in EAST tokamak显示文摘A detailed analysis of the synchrotron radiation intensity and energy of runaway electrons is presented for the Experimental Advanced Superconducting Tokamak(EAST). In order to make the energy of the calculated runaway electrons more accurate, we take the Shafranov shift into account. The results of the analysis show that the synchrotron radiation intensity and energy of runaway electrons did not reach the maximum at the same time. The energy of the runaway electrons reached the maximum first, and then the synchrotron radiation intensity of the runaway electrons reached the maximum.We also analyze the runaway electrons density, and find that the density of runaway electrons continuously increased. For this reason, although the energy of the runaway electrons dropped but the synchrotron radiation intensity of the runaway electrons would continue rising for a while. | 张永宽 周瑞杰 胡立群 陈美文 晁燕 EAST team | 2018 | Chinese Physics B2018，27，5： | 1 |
