An efficiency enhancement for a gyrotron backward-wave oscillator (gyro-BWO) through local variation of guiding magnetic field by special law is investigated using computer simulation. As result, more number of bunched beam electrons take up position in energy-losing phase for chosen gyro-BWO’s parameters or other gyro-devices. An accelerator device buncher provides analogous effect for acceler...

This paper is concerned with the benefits of using rotational measurements of a gyroscope in conjunction with optical flow to determine the instantaneous rigid motion. It presents an experimental study focusing on three main aspects: speedup, resolving ambiguities due to local minima and accuracy. For this sake, we developed a method to minimize simultaneously the reprojected optical flow error...

This paper presents a very simple, yet very effective method for combining measurements from a gyro with measurements from wheel encoders (odometry). Sensor-fusion of this kind has been done before, usually by means of a statistical model that describes the behavior of the gyro and the behavior of the odometry component. However, because these systems are based on models, they cannot anticipate...

Finite electron gyro-radius influences on the trapping and charge density distribution of holes limited transverse extent are calculated analytically explored by numerical orbit integration in low to moderate magnetic fields. Parallel is shown depend upon gyro-averaged potential energy give rise deficit. Both types average expressible as convolutions with perpendicular Gaussians width equal the...

To overcome the effect of temperature on laser gyro zero bias and to stabilize the laser gyro output, this study proposes a modified radial basis function neural network (RBFNN) based on a Kohonen network and an orthogonal least squares (OLS) algorithm. The modified method, which combines the pattern classification capability of the Kohonen network and the optimal choice capacity of OLS, avoids...

The theory, design and experimental results of a wideband 140 GHz, 1 kW pulsed gyro-traveling wave amplifier are presented. The gyro-TWA operates in the HE(0,6) mode of an overmoded quasi-optical waveguide using a gyrating electron beam. The electromagnetic theory, interaction theory, design processes and experimental procedures are described in detail. At 37.7 kV and 2.7 A beam current, the ex...
