This paper presents an All-in-one simulation method for klystron. The simulation results compared with conventional simulation results are also presented. Conventional simulation method calculates the klystron in part. The electron gun, beam-wave interaction and the collector are designed respectively, and thus the simulation results are inauthentic commonly. The All-in-one simulation method uses...
The extended interaction oscillator (EIO) is regarded as a novel type of high power terahertz (THz) source, which has promising application prospects in radar, medical imaging etc. Up to now, CPI and other institutes have developed many types of EIO. For satisfying with the application request, the EIO with operation frequency exceeding 300GHz is designed and studied with three-dimensional particle-in-cell...
The extended interaction oscillator (EIO) is regarded as a novel type of high power terahertz (THz) source, which has promising applications prospects in military radar, medical imaging and wireless communications, etc. For being satisfied with the widely applications, a THz EIO operation at G-band is designed and studied with three-dimensional particle-in-cell simulation at IECAS. To improve the...
This paper presents the design methodology and detailed design of the interaction circuit for use in an L-band 10-MW MBK, which operating in the fundamental mode at a center frequency of 1.3 GHz. Coaxial cavities are adopted to give adequate space for the use of multiple large cathodes, which has a low cathode loading and thereby facilitate a long lifetime. The emphasis for the present design is on...
A sheet-beam Extended Interaction Klystron (SBEIK) is an attractive MMW amplifier because of its high gain per unit length and compact configuration. The output cavity is an important part of the whole tube, which is used for RF power extraction. In this paper, multi-gap extended output cavity designs of SBEIK are presented by 3D simulations, RF parameters have been calculated. Beam wave interaction...
Steam generator (SG) is one of the key important equipments to safety of nuclear power plant (NPP), its reliability is the one vital weakness of nuclear steam supply system (NSSS), so it is necessary for ageing management (AM) to increase its reliability for safety operation. However the SG AM data has not always been readily available, thus the Ageing Management Database of the Steam Generator of...
