Abstract

The application discloses a device for monitoring the spatiotemporal evolution of ion electric thruster beam scintillation. The device includes a vacuum chamber, a first support structure for fixing a thruster on the vacuum chamber, an ion thruster, a casing of the thruster, a screen grid electrode, an acceleration grid electrode, a deceleration grid electrode, a wire connecting the electrodes, and the device is installed in the vacuum chamber. The wall is used to transmit the signal line and flange of the diagnostic information, the monitoring device for the measurement of the loop volt-ampere characteristic, the high-speed camera array for the beam scintillation spatiotemporal characteristic monitoring, the second support structure for the camera position fixation and installation. The present application solves the problems of precise positioning of the beam scintillation space position and time evolution characteristic tracking of the ion electric thruster in a closed and high vacuum environment, and overcomes the difficulty in determining the beam scintillation occurrence position by the traditional single monitoring loop volt-ampere characteristics, The problem of flicker type identification. Secondly, the device can comprehensively monitor the spatial and temporal evolution characteristics of beam scintillation.

Description

technical field [0001] The present application relates to the technical field of aerospace electric propulsion and the field of industrial low-temperature plasma coating, and in particular, to an ion electric thruster beam scintillation spatiotemporal evolution monitoring device. Background technique [0002] Ion thrusters for space use electrical energy to ionize propellant to generate plasma, and extract, accelerate and discharge ions through a high-voltage grid system to generate thrust. Due to the interaction of plasma, neutral gas and high-voltage electrodes during the working process of the ion thruster, abnormal beam scintillation (unexpected discharge) problems inevitably exist during the working process of the ion thruster, which is a serious problem. It will affect the performance and life reliability of the ion thruster. However, since beam scintillation is a millisecond-level transient process and the location of beam scintillation is uncertain, usually only the...
