Standard/Handbook for Multipactor Breakdown Prevention in Spacecraft Components
|Publication Date:||1 January 2016|
This document is intended to serve as a standard and handbook for the prevention of multipactor breakdown in spacecraft components and systems. The document provides minimum requirements for risk definition, system analysis, and component analysis and test. Supporting documentation describes proper design, analysis, and test guidelines while also providing the requirements for defining the proper system engineering to identify RF breakdown risks within susceptible components. The document framework is based on defining worst-case parameters as general inputs to analysis or test criteria for all components within the RF system. Using hardware-specific values, these worst-case parameters are defined separately from margin requirements.
With properly defined worst-case conditions, the document addresses required margins for analysis and test for multiple devices categories. Subsequent sections provide minimum verification requirements to demonstrate the margin recommendations for both analysis and test. Applicability of different analysis and test methods to the device class categories is provided, with special cases and considerations.
Multiple appendices based on state-of-the-art industry best practices are also provided as guidelines to aid manufacturers and contractors. Typical approaches including examples for both design and test are provided. A reference geometry is described along with corresponding analysis and test data. This information can be used as a benchmark standard, such that component vendors and manufacturers can have a standard example for RF breakdown.
Incorporating this document and its improved process into the development and test cycles of an RF component will reduce the risks associated with multipactor breakdown failure. The document goal is to concurrently reduce program risk as well as elevated cost of excessive margin requirements. This document shall serve as a baseline and minimum set of criteria for low-risk development and verification of RF spacecraft components.
