| 12 | Modeling process of the neutral beam re-ionization loss显示文摘The basic process of re-ionization loss was studied.In the drift duct there are three processes leading to re-ionization loss:the collision of neutral beam particles with the molecules of background gas,similar collisions with released molecules from the inner wall of the drift duct and the ferret-collisions among particles with different energy of the neutral beam.Mathematical models have been developed and taking EAST-NBI parameters as an example,the re-ionization loss was obtained within these models.The result indicated that in the early stage of the neutral beam injector operation the released gas was quite abundant.The amount of re-ionization loss owing to the released gas can be as high as 60%.In the case of a long-time operation of the neutral beam injector,the total re-ionization loss decreases from 13.7% to 5.7%.Then the reionization loss originating mainly from the collisions between particles of the neutral beam and the background molecules is dominant,covering about 92% of the total re-ionization loss.The drift duct pressure was the decisive factor for neutral beam re-ionization loss. | 梁立振 胡纯栋 谢远来 谢亚红 NBI组 | 2010 | Chinese Physics C2010,34,7: | 1 |

| 16 | Technical Design of Arc-Discharge and Deceleration Power Supply for MW Level NBI System on HL-2A Tokamak显示文摘Neutral beam injection (NBI) is one of the most effective ways to heat and drive plasma in a tokamak.The mega watt level neutral beam injector on the HL-2A tokamak con-sists of four high-power ion sources.Each source is supplied by discharge,beam extraction and auxiliary power supplies.Some circuit topologies and control sequences designed for the system are presented in this paper.Some important technologies such as the notching circuit,insulated gate bipolar transistor (IGBT) series-connected switch,high-frequency switching power supply and control system based on a digital signal processor (DSP) have been used.The system can be effectively used for high current ion beam extraction,protection,ion optics and so on.The power system has been safely used in HL-2A high-parameter NBI experiments for three years.The power of NBI can be kept at higher than 0.75 MW for 1 second and the ion beam power extracted from the ion source is higher than 2 MW.The ion temperature of the plasma center is close to 2.0 keV.These results show that the design of this power system is reasonable and reliable,and it can fully meet the system requirements for NBI of the HL-2A tokamak. | 陈文光 饶军 李波 雷光玖 曹建勇 王明伟 康自华 冯鲲 HL-2A NBI Group | 2012 | Plasma Science and Technology2012,14,10: | 1 |

| 19 | Thermal analysis of EAST neutral beam injectors for long-pulse beam operation显示文摘Two sets of neutral beam injectors(NBI-1 and NBI-2) have been mounted on the EAST tokamak since 2014. NBI-1 and NBI-2 are co-direction and counter-direction, respectively. As with indepth physics and engineering study of EAST, the ability of long pulse beam injection should be required in the NBI system. For NBIs, the most important and difficult thing that should be overcome is heat removal capacity of heat loaded components for long-pulse beam extraction. In this article, the thermal state of the components of EAST NBI is investigated using water flow calorimetry and thermocouple temperatures. Results show that(1) operation parameters have an obvious influence on the heat deposited on the inner components of the beamline,(2) a suitable operation parameter can decrease the heat loading effectively and obtain longer beam pulse length, and(3) under the cooling water pressure of 0.25 MPa, the predicted maximum beam pulse length will be up to 260 s with 50 keV beam energy by a duty factor of 0.5. The results present that, in this regard, the EAST NBI-1 system has the ability of long-pulse beam injection. | 胡纯栋 许永建 谢远来 谢亚红 梁立振 蒋才超 刘胜 韦江龙 盛鹏 刘智民 陶玲 the nbi team | 2018 | Plasma Science and Technology2018,20,4: | 0 |
