title: Analysis and Experimental Study of Impedance Matching Characteristic of RF Ion Source on Neutral Beam Injector

description: The impedance matching circuit is the important unit for the RF ion source, which is used to match the electric parameters of the RF generator and ion source antenna in order to transfer the RF power to the RF antenna of ion source and to get stable plasma. The plasma impedance will be changed during the plasma generation, since the impedance characteristic is not easy to be calculated and measured; it also necessary to do more experimental study. In this paper, the impedance matching unit was analyzed and designed according to the principle of RF ion source. The matching characteristic was studied during the experiment, and we achieved the best impedance matching characteristic. It also verified the good design of impedance matching unit. Based on the results of impedance matching studies, high-RF stable plasma discharge was achieved.

title: The Development of Power Supply for Negative Ion Source Extraction Grid
title: The Development of Power Supply for Negative Ion Source Extraction Grid

description: The extraction grid power supply (EGPS) is important for neutral beam injection of tokamak, which is used to extract the negative ions from the plasma source. A set of power supply with pulse step modulation topology at 16 kV/20 A has been designed for the negative ions extraction at the Institute of Plasma Physics, Chinese Academy of Sciences, which meets the requirements of fast dynamics, low ripple, and good output operation. The development of EGPS is presented in this paper. Two different voltage ratings and series-connected switched power supply (SPS) modules are fed from multisecondary transformer.Insulated-gate bipolar transistors are applied to the switch of SPS module. Rise time and fall time of EGPS out voltage can be set from few microseconds to milliseconds. When the overcurrent occur, the output voltage falls to zero less than 5 μs. The dynamic performance tests with dummy load of EGPS are presented. The testing results indicate that the power supply meets the demands of negative ions extraction. The design provides a foundation for the next phase of extraction experimental operation for radio frequency ion source.

title: Study on the series resistance of betavoltaic batteries
title: Study on the series resistance of betavoltaic batteries

description: The series resistance (Rs) is one of the essential factors that affect the performance of betavoltaic batteries. However, the Rs value of betavoltaic batteries tends to be anomaly high when it is extracted from the IV characteristic curve. To explore the reasons for this phenomenon, different injection conditions and their impacts on Rs of betavoltaic and photovoltaic cells were compared and analyzed, since photovoltaic cells have an in-depth study on Rs and have similar principles to betavoltaic cells. The results show that the Rs will be significantly affected by the injection conditions, and the high resistance of the depletion region under low level radiation injection of betavoltaic batteries is the main reason for their high Rs. The effect of high Rs on betavoltaic battery’s performance was further explored, and the results show that the IV characteristic curve will be distorted obviously when Rs is close to or higher than the shunt resistance and it thus leads to a significant decrease in the battery’s fill factor and energy conversion efficiency. The effect of the input power on Rs should be considered in the future analysis of betavoltaic batteries. This work provides theoretical support for the parameter analysis of betavoltaic batteries.

title: Design and Preparation of SiC Radiation Isotope Battery
title: SiC辐射伏特式同位素电池的设计及制备研究

description: Radiation voltaic isotope batteries have long service life and are easy to miniaturize, making them an excellent choice in the field of micro energy. The use of wide-bandgap semiconductor materials as battery transducer elements theoretically has higher efficiency, but the efficiency value of the samples prepared in the experiment is still low, only at the level of 1%. This article comprehensively analyzes the factors affecting efficiency and points out the importance of the preparation process. Through theoretical calculations and numerical simulation methods, the theoretical output performance of the isotope battery under four representative semiconductor materials and two typical transducer configurations is compared and analyzed. The results show that the theoretical efficiency of the PIN structure SiC battery is the highest, reaching 17%. Combined with the level of preparation technology, optimized design for PIN-type SiC battery and sample preparation were carried out. Under 10 mCi 63Ni source irradiation conditions, the battery samples obtained short-circuit current 8~10 nA, open-circuit voltage 0.45~0.82 V, and efficiency 0.26%~0.60%. Compared with the theoretical design value, the experimental test results still have a certain gap. Through analysis, it is clear that the surface technology is the focus of improving battery performance in the future.

title: Influence of Solid Beta Sources Selection on Direct Charge Nuclear Battery
title: 固态同位素β源选择对直充式核电池性能的影响

description: Direct charge radioisotope battery having the advantages of long service lifetime, simple structure, high open circuit voltage and easily miniaturized, is a promising source for the great power of Micro-Electro-Mechanical System. Although the beta sources are the main choice for direct charge nuclear battery in the present studies,but no systematic analysis and comparison on beta sources is presented. In this work, the properties of six beta sources (including 3H(Ti3H2), 14C, 35S, 45Ca, 63Ni and 147Pm) were studied by software simulation and theoretical calculation. This study includes the differences of energy conversion efficiency and the theoretical output power for direct charge nuclear battery. The calculated results showed that the energy conversion efficiency was positively correlated with the average energy of emitted radioactive particles, and the theoretical output power was negatively correlated with half-life of beta source. 147Pm was the preferred choice considering long life, the energy conversion efficiency and the theoretical output power.
