Genetic Algorithm (GA) is used to design the parameters of the distributed-loss circuit of gyrotron traveling-wave amplifier (gyro-TWA). The optimization results have been found to maximize the gain of the device.
A nonlinear steady-state multimode theory is developed to investigate mode competition in gyro-TWT. Calculation shows that competition mode may be suppressed by a large driving power in a particular range.
The purpose of this paper is to show how classical linear stochastic systems can be physically implemented using quantum optical components. Quantum optical systems typically have much higher bandwidth than electronic devices, meaning faster response and processing times, and hence have a potential for providing better performance than classical systems. A complete procedure is proposed for a stable...
We proposed a new and low cost design of time-to-digital converter (TDC) based on Vernier method using only one FPGA EPF10K30ATI144-3 with 1.3 ns timing resolution performance. Neither ECL (emitter-coupled logic) circuit nor high frequency clock was used in this design, which greatly reduced the complication and the power supply. We used two oscillators with slightly different frequencies to measure...
