    Statistical Modeling for Radiation Hardness Assurance: Toward Bigger Data

    Get PDF
    New approaches to statistical modeling in radiation hardness assurance are discussed. These approaches yield quantitative bounds on flight-part radiation performance even in the absence of conventional data sources. This allows the analyst to bound radiation risk at all stages and for all decisions in the RHA process. It also allows optimization of RHA procedures for the project's risk tolerance

    Bayesian Methods for Bounding Single-Event Related Risk in Low-Cost Satellite Missions

    A Comparison of High-Energy Electron and Cobalt-60 Gamma-Ray Radiation Testing

    Get PDF
    In this paper, a comparison between the effects of irradiating microelectronics with high energy electrons and Cobalt-60 gamma-rays is examined. Additionally, the effect of electron energy is also discussed. A variety of part types are investigated, including discrete bipolar transistors, hybrids, and junction field effect transistor

    Confidence Level Based Approach to Total Dose Specification for Spacecraft Electronics

    Get PDF
    A confidence level based approach to total dose radiation hardness assurance is presented for spacecraft electronics. It is applicable to both ionizing and displacement damage dose. Results are compared to the traditional approach that uses radiation design margin and advantages of the new approach are discussed

    Vulnerability of a variety of candidate spacecraft electronics to total ionizing dose and displacement damage is studied. Devices tested include optoelectronics, digital, analog, linear bipolar devices, and hybrid devices

    Single-Event Effect Testing of the Vishay Si7414DN n-Type TrenchFET(Registered Trademark) Power MOSFET

    Get PDF
    This study was being undertaken to determine the single event effect susceptibility of the commercial Vishay 60-V TrenchFET power MOSFET. Heavy-ion testing was conducted at the Texas AM University Cyclotron Single Event Effects Test Facility (TAMU) and the Lawrence Berkeley National Laboratory BASE Cyclotron Facility (LBNL). In addition, initial 200-MeV proton testing was conducted at Massachusetts General Hospital (MGH) Francis H. Burr Proton Beam Therapy Center. Testing was performed to evaluate this device for single-event effects from lower-LET, lighter ions relevant to higher risk tolerant space missions

    Destructive Single-Event Effects in Diodes

    Get PDF
    In this work, we discuss the observed single-event effects in a variety of types of diodes. In addition, we conduct failure analysis on several Schottky diodes that were heavy-ion irradiated. High- and low-magnitude optical microscope images, infrared camera images, and scanning electron microscope images are used to identify and describe the failure locations
