The robustness of impurity-seeded radiative mantle solutions for ITER to uncertainties in several physics and operating parameters is examined. The results indicate that (approximately) 50--90% of the input power can be radiated from inside the separatrix with Ne, Ar and Kr injection, without significant detriment to the core power balance or collapse of the edge temperature profile, for a wide range of conditions on the impurity pinch velocity, edge temperature pedestal, and plasma density.

An end to greenhouse gas emissions, a global framework to control nuclear proliferation, a preemptive remedy to looming water wars, and unlimited energy worldwide are just a few of the concrete solutions offered up in Tom Blees's brilliant and timely Prescription for the Planet. Everyone is worried about global warming, energy wars, resource depletion, and air pollution. But nobody has yet come up with a real plan to resolve these problems that can actually work-until now. Prescription for the Planet proposes a workable blueprint to virtually eliminate greenhouse gas emissions by the middle of this century and solve a host of other seemingly intractable global problems. Solving our planet's most pressing dilemmas requires more than simply setting goals. We need a roadmap to reach them. Technologies that work fine on a small scale cannot necessarily be ramped up to global size. Worldwide environmental and social problems require a bold vision for the future that includes feasible planet-wide solutions with all the details. Prescription for the Planet explains how a trio of little-known yet profoundly revolutionary technologies, coupled with their judicious use in an atmosphere of global cooperation, can be the springboard that carries humanity to an era beyond scarcity. And with competition for previously scarce resources no longer an issue, the main incentives for warfare will be eliminated. Explaining not only the means to solve our most pressing problems but how those solutions can painlessly lead to improving the standard of living of everyone on the planet, Blees's lucid and provocatively written Prescription for the Planet has arrived not a moment too soon. There is something here for everyone, be they a policymaker, environmental activist, or any concerned citizen hoping for a better future.

The technology of the next few decades could possibly allow us to explore with robotic probes the closest stars outside our Solar System, and maybe even observe some of the recently discovered planets circling these stars. This book looks at the reasons for exploring our stellar neighbors and at the technologies we are developing to build space probes that can traverse the enormous distances between the stars. In order to reach the nearest stars, we must first develop a propulsion technology that would take our robotic probes there in a reasonable time. Such propulsion technology has radically different requirements from conventional chemical rockets, because of the enormous distances that must be crossed. Surprisingly, many propulsion schemes for interstellar travel have been suggested and await only practical engineering solutions and the political will to make them a reality. This is a result of the tremendous advances in astrophysics that have been made in recent decades and the perseverance and imagination of tenacious theoretical physicists. This book explores these different propulsion schemes – all based on current physics – and the challenges they present to physicists, engineers, and space exploration entrepreneurs. This book will be helpful to anyone who really wants to understand the principles behind and likely future course of interstellar travel and who wants to recognizes the distinctions between pure fantasy (such as Star Trek’s ‘warp drive’) and methods that are grounded in real physics and offer practical technological solutions for exploring the stars in the decades to come.

This book contains the papers presented at the Course on "Tokamak Startup - Problems and Scenarios Related to the Transient Phases of a Thermonuclear Fusion Reactor" which was held in Erice, July 14-20, 1985. The fact that the critical startup and transient phases of a tokamak reactor are now the specific subject of a comprehensive international gathering of fusion specialists seems indicative of the substantial pro gress made in recent years towards attaining controlled ignition of a nuclear fusion fuel, i.e. towards demonstrating the scientific feasibili ty of controlled thermonuclear fusion. In fact, the steady-state burning phase has attracted so far most of the attention of fusion physicists and engineers, as it is conceptually more rewarding, and theoretically easier to handle.

This book provides readers with an introductory understanding of Inertial Electrostatic Confinement (IEC), a type of fusion meant to retain plasma using an electrostatic field. IEC provides a unique approach for plasma confinement, as it offers a number of spin-off applications, such as a small neutron source for Neutron Activity Analysis (NAA), that all work towards creating fusion power. The IEC has been identified in recent times as an ideal fusion power unit because of its ability to burn aneutronic fuels like p-B11 as a result of its non-Maxwellian plasma dominated by beam-like ions. This type of fusion also takes place in a simple mechanical structure small in size, which also contributes to its viability as a source of power. This book posits that the ability to study the physics of IEC in very small volume plasmas makes it possible to rapidly investigate a design to create a power-producing device on a much larger scale. Along with this hypothesis the book also includes a conceptual experiment proposed for demonstrating breakeven conditions for using p-B11 in a hydrogen plasma simulation. This book also: Offers an in-depth look, from introductory basics to experimental simulation, of Inertial Electrostatic Confinement, an emerging method for generating fusion power Discusses how the Inertial Electrostatic Confinement method can be applied to other applications besides fusion through theoretical experiments in the text Details the study of the physics of Inertial Electrostatic Confinement in small-volume plasmas and suggests that their rapid reproduction could lead to the creation of a large-scale power-producing device Perfect for researchers and students working with nuclear fusion, Inertial Electrostatic Confinement (IEC) Fusion: Fundamentals and Applications also offers the current experimental status of IEC research, details supporting theories in the field and introduces other potential applications that stem from IEC.
