Description

technical field [0001] The invention belongs to the technical field of space radiation effect and reinforcement, and in particular relates to an on-orbit monitoring device and method for space single particle burnout effect. Background technique [0002] The single event effect caused by the interaction between a single high-energy particle in space and a microelectronic device or circuit is one of the important factors that induce on-orbit failure and abnormal operation of spacecraft. A single high-energy particle penetrates a power MOSFET device and generates a large current at a sensitive node inside the device, thereby inducing a single event burnout effect that is a catastrophic failure that will cause serious damage to the spacecraft, especially for satellites that use a large number of power MOSFET devices. The secondary power supply system will pose a fatal threat and seriously affect the long life and high reliability flight of the spacecraft in orbit. [0003] Wit...

Problems solved by technology

Existing single event burnout monitoring has carried out a lot of research work mainly on the monitoring and protection of single event burnout, and has not conducted a comprehensive detection and analysis of the pulse signal when single event burnout occurs. Therefore, in order to meet the needs of the development of existing spacecraft , it is necessary to design a single particle burning monitoring method, which not only needs to realize pulse signal counting and record single particle burning times during high current, but also realizes pulse width and amplitude detection of pulse signals. For this reason, the present invention designs An on-orbit monitoring method suitable for space single event burnout effect, through logarithmic converter and pulse height analyzer, it realizes wide dynamic range measurement and pulse width and amplitude measurement of pulse signal, which can fully characterize single event burnout effect feature information
