  • Analysis and Simulations of Space Radiation‐Induced Single‐Event Effects and Transients

    Spacecraft electronics are affected by the space radiation environment. Among the different types of radiation effects that can affect spacecraft electronics is the single‐event transient (SET). This chapter explores the origins of SETs and their effects as outlined by many scientists and researchers, many of which are mentioned in the references. It also explores the modeling of a SET in digital and analog circuit. The chapter also addresses the concept of crosstalk that could develop among digital circuits in the present of a SET event. It provides a discussion of SET hardening. The chapter presents a qualitatively methodology for assessing SETs and its effects so that spacecraft avionics engineers can develop either hardware or software countermeasures in their designs. Single‐event effects is the general term used when space energetic particles are capable of creating an electrical response in an electronics device.

  • Impulse Characteristics of Grounding Devices

    This chapter introduces the phenomena and mechanism of soil electrical breakdown, the numerical analysis method and impulse characteristics of ground devices and ground grids, impulse effective length of grounding electrodes, and the lightning electromagnetic field generated by grounding electrode.

  • Electrical Breakdown in Gases

    This chapter discusses a short treatise on atomic collisions in gases and a description of Townsend's experiments in the early twentieth century. It presents the Paschen curve, and describes the predominant theories of spark formation. The chapter also discusses other breakdown phenomena, such as coronas and the hollow electrode carrier generation used in pseudosparks. Electrical breakdown occurs in a gas when a high‐conductivity channel is formed between cathode and anode. Before a study is made of the behavior of gases under the influence of an electric field, it is appropriate to review the basic principles of the kinetic theory of gases pertinent to gaseous ionization and breakdown. From there, the various concepts of ionic and electronic can be inferred. The chapter further discusses the efficient use of gaseous insulation with intershields. It concludes by discussing the important aspects of breakdown behavior in gaseous SF6.

  • Fundamentals of Electrical Discharges

    Natural phenomena, such as gamma rays produced by radioactive decay processes in the soil and cosmic radiation originating from solar flares and other galactic objects, can ionize the air molecules. This chapter first discusses ionization and deionization processes in gases. This is followed by a discussion on ionization and attachment coefficients. Two typical breakdown mechanisms occur in gases, each of them operating under specifically favorable conditions: Townsend's mechanism and the streamer mechanism. Corona discharges in air can burn on the overstressed zones of hot electrodes. This kind of discharge occupies a short layer, attached to the energized conductor. When a conductor is in corona, then the electric field on the surface is somehow influenced by the surrounding ion space charge. Kaptzov's hypothesis (KH) relates to the assumption that the space charge emitted into the interelectrode gap is in amounts that hold the surface field at the onset level.

  • Feasibility of the Lubistor-Based Avalanche Phototransistor

    In the twenty-first century, the traffic carried by optical communication systems will grow year by year, and the provision of rock-solid communication reliability is mandatory. Quantum communication technology is one of the most promising candidates for realizing truly reliable communication. Although the scientific and engineering bases for quantum communication remain under development, many scientists and engineers are carrying out challenging research to try to achieve significant breakthroughs in the near future. I have tried to discuss how the new Lubistor will contribute to meeting the technological challenges.

  • Ionization Processes

    The ionization process of atoms or molecules is through energizing the electrons causing them to leave stable orbit revolving around the nucleus and becoming free-moving charges. The main mechanisms for ionization consist of thermal, electron impact, chemical reactions, photoionization, and microwave or electron cyclotron resonance. This chapter describes the ionization that focus on the basic mechanisms of photoemission, thermal, and electron impact discharges. The equilibrium ionization of the mixture of electrons, ions, and neutral particles can be analyzed by the law of mass action and the electronic partition function. Under gas discharge conditions, ionization by electron impact dominates over the photoionization because the cross sections of photoionization close to the ionizing threshold are rather high. The chapter provides Saha equation of ionization. An important parameter for the ionization rate is the mean free path of the gas medium and is ultimately related to the collision cross section.

  • Optimization and Comparison of Power Devices

    We begin this chapter with a discussion of avalanche breakdown and blocking voltage in power devices, which leads naturally into a survey of edge termination techniques. We then discuss the optimum design of unipolar drift regions in devices such as Schottky diodes, JFETs (junction field-effect transistors), and MOSFETs (metal-oxide-semiconductor field effect transistors), with a brief discussion of lateral RESURF (reduced-surface- field) devices. Finally, we present a consistent methodology for optimizing and comparing unipolar and bipolar devices for a particular set of specifications (i.e., blocking voltage and switching frequency).

  • Particle-Solid Scattering

    This chapter contains sections titled: * Overview * Scattering Cross Section * Electron Beam Spectroscopies * Auger Electron Spectroscopy * Auger Depth Profiling * Summary

  • Modeling Electron Impact Ionization

    Electron impact ionization is the mainstay for plasma-based flow control actuators because it actuates in less than microseconds and the electrode configuration can be made nonintrusive to oncoming stream. In addition, when the actuator is not needed, unlike most mechanical flow control devices, it will not be parasitic and degrade performance of aerospace vehicles. The space charges induce an additional electric field potential that makes it different from the corona discharge. This chapter presents the best physics-based, multifluid model for the electron impact ionization. The physics for electron impact ionization is well known through the luminary contributions by Townsend, the ionization is evolving from the electrons collision, secondary emission, and avalanche. The secondary emission from cathode arises as controlling mechanism for all electron impact ionization. A high concentration of positive charges over an electrode creates an extremely high electrical field potential, which is comparable to the magnitude in a nuclei.
