The invention provides a lateral output device for a wave gyro traveling wave tube, and belongs to the millimeter wave source technical field of the high-power millimeter wave technology, particularly a lateral output device for a wave gyro traveling wave tube, wherein a Gaussian beam can be directly outputted. In the prior art, a wave gyro traveling wave tube must be externally connected with a waveguide mode converter. In order to overcome the above defect in the prior art, the invention provides a novel output device for a wave gyro traveling wave tube. The output device comprises a transition waveguide section, a 90-degree waveguide turning section and a circular waveguide radiator.

Since a measurement of a magnetostriction is accompanied by a measurement of a magnetization of a sample to be measured, the magnetostriction and the magnetization are measured by separately prepared devices, with efforts for observing the coextensive volumes of the sample. Measurements of the magnetostriction and the magnetization are difficult due to the difficulty of correction and calibration. The value of macroscopic external mode magnetostrictive coefficient cannot be correctly determined at low temperature regions. A convenient method which enables the measurement of the magnetostriction and the magnetization simultaneously at the coextensive volumes of the sample, is developed by combining the method of the measurement of the magnetostriction by an X-ray diffraction method an the method of the X-ray magnetic diffraction method. This method comprises the steps of measuring the relative diffraction intensity change (δ) at ascending magnetic field and the descending magnetic field respectively in the magnetic field at the coextensive volumes of the sample, obtaining asymmetry component δA and symmetry component δS of the magnetic field (H) from the measured relative intensity change (δ) in the magnetic field at said volumes of said sample, obtaining magnetostrictive coefficient (δ100) at said volumes of the sample based on said asymmetry component (δS), and obtains relative magnetization (M / Ms) at said volumes of said sample based on the value (R′a) obtained by recomposing said asymmetry component (δA) and symmetry component (δS). This method is advantageous for calibration of devices, when using the condition wherein the microscopic value of crystallographical magnetostrictive coefficient measured by X-rays corresponds to the macroscopic value of external magnetostrictive coefficient.
