Stable, high efficiency gyrotron backward-wave oscillator
Stability issues have been a major concern for the realization of broadband tunability of the gyrotron backward-wave oscillator gyro-BWO . Multimode, time-dependent simulations are employed to examine the stability properties of the gyro-BWO. It is shown that the gyro-BWO is susceptible to both nonstationary oscillations and axial mode competition in the course of frequency tuning. Regions of n...
متن کاملCharacteristics of a High-Power Backward Wave Oscillator
AbstructThis paper discusses an approach to model the inputloutput characteristics of the Sinus-6 electron beam accelerator-driven backward wave oscillator. Since the Sinus-6 is extremely fast to warrant the inclusion of dynamical effects, and since the sampling interval in the experiment is not fixed, a static continuous neural network model is used to fit the experimental data. Simulation res...
متن کاملRELATIVISTIC KLYSTRON RESEARCH FOR HIGH GRADIENT ACCELERATORSt
Relativistic klystrons are being developed as a power source for high gradient accelerator applications which include large linear electron-positron colliders, compact accelerators, and FEL sources. We have attained 200MW peak power ‘at 11.4 GHz from a relativistic klystron, and 140MV/m longitudinal gradient in a short 11.4 GHz accelerator section. We report here on the design of our first klys...
متن کاملX-band Klystron Development at Slac
The development of X-band klystrons at SLAC originated with the idea of building an X-band Linear Collider in the late 1980’s. Since then much effort has been expended in developing a reliable X-band Power source capable of delivering >50 MW RF power in pulse widths >1.5 μs. I will report on some of the technical issues and design strategies which have led to the current SLAC klystron designs.
متن کاملTowards coherent combining of X-band high power microwaves: phase-locked long pulse radiations by a relativistic triaxial klystron amplifier
The radio-frequency breakdown due to ultrahigh electric field strength essentially limits power handling capability of an individual high power microwave (HPM) generator, and this issue becomes more challenging for high frequency bands. Coherent power combining therefore provides an alternative approach to achieve an equivalent peak power of the order of ∼100 GW, which consequently provides opp...
