In present work, the test of terahertz Extended Interaction oscillator is reported. The high frequency structure (HFS) is employed with the folded waveguide, which is fabricated with high speed numerical milling. The preliminary test shows that the oscillator can produce the power exceeds 2W at operating frequency 308GHz. The optimum design is going forward as planned.
This paper presents the simulation study of a C band klystron with a disc-load waveguide traveling wave output structure. The electron gun with a perveance of 1.5μp is designed. A 3-cell disc-loaded waveguide output structure working at π/2 mode is adopted in the circuit design. The beam-wave interaction system with disc-loaded waveguide output structure is simulated by PIC code. More than 50MW output...
In this paper, a novel terahertz (THz) extended interaction oscillator (EIO) is presented. Adopting PIC code, design and optimization geometry of EIO is performed, which is composed of ladder loaded rectangular waveguide. In present work, the operation center frequency of THz EIO is 105GHz, and the output power 673W is achieved, the efficiency reaches 12.1%, which is beam voltage and beam current...
In China, the R&D of high peak power klystron has been made much progress in recent years. In 2010, the Institute of Electronics, Chinese Academy of Sciences (IECAS) has successfully developed S-band 100MW klystron, and, currently, are developing an S-band 150MW klystron. The Institute of High Energy Physics, Chinese Academy of Sciences (IHEP) cooperated with the Hang Guang Electrical Factory...
Free space laser communication becomes one of the most attractive research pot of next generation optical communication technologies due to its advantages of large data transmission amount, high directionality of transmission and high transmission security. The tapered semiconductor lasers are one of the most important optical sources in such systems. In this paper, we introduce the structure design,...
