    Description / Table of Contents: This volume provides a benchmark statement from the world's leading geomorphologists on the state of, and potential changes to, the environment. Focusing on catalysts of landscape change other than climate, including relief, hydroclimate, sea-level variations and human activity, it is valuable for advanced students, researchers, policymakers and environmental managers.

    Description / Table of Contents: In recent years, statistical mechanics has been increasingly recognized as a central domain of mathematics. Major developments include the Schramm-Loewner evolution, which describes two-dimensional phase transitions, random matrix theory, renormalization group theory and the fluctuations of random surfaces described by dimers. The lectures contained in this volume present an introduction to recent mathematical progress in these fields. They are designed for graduate students in mathematics with a strong background in analysis and probability. This book will be of particular interest to graduate students and researchers interested in modern aspects of probability, conformal field theory, percolation, random matrices and stochastic differential equations.

    Notes: A CsI salt-based cathode which is capable of producing a modest perveance, 10 s of A/cm2 electron beam for several microseconds pulse lengths, and has little susceptibility to diode closure has been experimentally characterized. This explosive field-emission CsI-coated carbon fiber cathode has operated in modest 10−5 Torr vacuums at voltages up to 160 kV, and can easily be configured to provide space-charge-limited solid or annular electron beams in arbitrarily large diameter configurations. The CsI cathode has demonstrated negligible closure for 2 μs pulses, and has operated for 200 shots with no degradation in cathode performance. Data on the operating performance of this salt cathode, including effective gap time history and streak photographs demonstrating uniformity of the current density, are presented. A comparison of CsI cathode performance with a velvet explosive field emitting cathode used in electron-beam production is also presented. © 1995 American Institute of Physics.

    Notes: We report the first gyrotron-backward-wave-oscillator experiments to produce high power (tube power of ∼1–8 MW), long-pulse (0.3–1.2 μs) microwaves at high currents (0.1–2 kA) and high voltages (650–750 kV). Experiments were performed in the TE11 fundamental backward-wave mode, with efficiencies of ∼1%–2%. Mode competition was observed which is believed to originate from the TE21 absolute instability.
