The output power could be adjusted with the change of control voltage, and the reflecting power could be gotten by measuring the output voltage of attenuator and detector. 4.The thrust measurement device was calibrated, and the accuracy was 2%FS. At the same time the signal of thrust measurement was input to the computer. E-type chromel-constantan thermocouple was used to measure the temperature of MPT, and the accuracy was 5%FS.The vacuum measurement was realized by using ZDF-5427M vacuometer, and the accuracy was 3%FS.

It basically consists of a ring cavity around which there are two laser beams traveling in the opposite direction, one clockwise and the other counterclockwise, and the beat note of the two counter propagating beams is proportional to the rotation rate of the ring cavity relative to an inertial frame.

Employing a 2.5D PIC code, A radial klystron oscillator with foldaway concentric cylinders resonant cavity is simulated numerically.

其特点为：径向尺寸小，起振电流低。用二维半PIC程序对折叠式谐振腔径向速调管振荡器进行数值模拟研究。

A circle is placed at the launch point to improve the interaction between the electron beam and the fields supported by the slow wave structure, thus to control the beam current density at the launch point, and to minimize the loss of the electron beam energy. The inaner radii of the extractor vanes are slightly larger than those of other SWS vanes, which increases the axial group velocity and enhances the microwave output power and efficiency. Implementation of two RF choke vanes stops the leakage of microwave pulse power toward the diode, and makes the device more compact than the conventional MILO.

该振荡器在阴极电子发射起点加圆环，控制此处电子束的发射密度，来减少电子能量的损耗，改善束－波互作用；逐渐加大慢波结构的后两个叶片的内半径，增大微波群速度，便于谐振腔中的能量输出，提高微波输出效率；采用两个扼流片有效地阻止了微波功率向二极管区泄漏，相应减小了器件的尺寸。
