| 1 | CALCULATION OF NONLINEAR MAGNETIC FIELDS IN CYLINDRICALLY SYMMETRIC SYSTEM显示文摘For the calculation of non-linear magnetic fields, a simple program can be as effective as a large commercialized software package. If relaxation methods are used, they must include successive over-relaxation and under-relaxation and much attention must be paid to the relaxation factor and the interpolation. In this paper some skills are proposed on the setting of an interpolation switch and the choosing of saturation point so as to assure satisfied convergence properties. The numerical results by using these methods conform well to the tests. | Wu Xunlei Chen Xinqiao Ding Yaogen (Institute of Electronics, Chinese Academy of Sciences, Beijing 100080) | 2003 | Journal of Electronics(China)2003，20，1： | 3 |

| 18 | DEVELOPMENT OF 50MW S-BAND KLYSTRON显示文摘This letter reports the development of a 50MW S-band klystron in the Institute of Electronics, Chinese Academy of Sciences (IECAS). It adopted a structure of six-cavity and single output window. Under conditions of an RF (Radio Frequency) pulse width of 4μs, a beam voltage of 305.9kV and a beam current of 368A, the peak output power has achieved 51.4MW with an efficiency of 45.6% and a gain of 54dB. | Wang Yong Xie Jingxin Ding Yaogen Liu Pukun | 2006 | Journal of Electronics(China)2006，23，3： | 1 |
| 19 | RECENT PROGRESS IN MULTI-BEAM KLYSTRON IN IECAS显示文摘Recent research progresses in Multi-Beam Klystron (MBK) in IECAS are briefly introduced in the letter. The S-band MBKs of IECAS have peak power of 120-250 kW, average power of 4-9 kW, efficiency of 35-45%, gain of 41-46 dB, beam voltage of 15-19 kV, and weight of 40-45 kg. Some key technical problems of MBK are also described and discussed. Among them,improving the design of MBK to obtain the required bandwidth, raising beam transmission to increase average power, eliminating oscillation and spray spectrum, overcoming window breakdown caused by magic mode, reducing breakdown times of electrongun, are most important things for the practical MBK. Besides, further research work in MBK in IECAS is commented. | Ding Yaogen (Institute of Electronics, Chinese Academy of Sciences, Beijing 100080) | 2002 | Journal of Electronics(China)2002，19，4： | 0 |
