-
0.00 - 4.00 Credits
Designed to stimulate students in the pursuit of research. Participants in this seminar discuss critically papers given by seminar members. Ordinarily, several staff members also participate. Often topics are drawn from published data that present unsolved puzzles of interpretation.
-
0.00 - 4.00 Credits
Students will prepare and deliver presentations and lead discussion about topics of current interest in observational astrophysics and techniques. The topic for this academic year will be instrumentation and the upcoming large astronomical projects.
-
0.00 - 4.00 Credits
An introductory course to plasma physics, with sample applications in fusion, space and astrophysics, semiconductor etching, microwave generation, plasma propulsion, high power laser propagation in plasma; characterization of the plasma state, Debye shielding, plasma and cyclotron frequencies, collision rates and mean-free paths, atomic processes, adiabatic invariance, orbit theory, magnetic confinement of single-charged particles, two-fluid description, magnetohydrodynamic waves and instabilities, heat flow, diffusion, kinetic description, and Landau damping. The course may be taken by undergraduates with permission of the instructor.
-
0.00 - 4.00 Credits
Introduction to Plasma Physics at the Graduate level. Principles and applications of magnetohydrodynamic and kinetic theory are discussed. These principles are fundamental to Plasma Science, and the illustrative applications are relevant to current magnetic fusion research and plasma astrophysics.
-
0.00 - 4.00 Credits
Wave phenomena in a cold magnetized plasma, including resonances, cut-offs, mode conversion, drift waves, weak collisions, energy transport and finite temperature effects over a wide range of frequencies. Development of the full hot plasma model for waves in locally homogeneous plasmas, including collisionless damping mechanisms such as Landau, cyclotron and TTMP damping, velocity-space instabilities and Nyquist analysis, hot plasma mode conversion, and Bernstein waves. Applications to plasma diagnostics, radiofrequency plasma heating and noninductive current drive, and magnetospheric propagation.
-
0.00 - 4.00 Credits
Introduction to theory of fluctuations and transport in plasma. Origins of irreversibility. Random walks, Brownian motion, and diffusion; Langevin and Fokker-Planck theory. Fluctuation-dissipation theorem; test-particle superposition principle. Statistical closure problem.

-
0.00 - 4.00 Credits
Introduction to experimental plasma physics, with emphasis on high-temperature plasmas for fusion. Requirements for fusion plasmas: confinement, beta, power and particle exhaust. Discussion of tokamak fusion and alternative magnetic and inertial confinement systems. Status of experimental understanding: what we know and how we know it. Key plasma diagnostic techniques: magnetic measurements, Langmuir probes, microwave techniques, spectroscopic techniques, electron cyclotron emission, Thomson scattering.
-
0.00 - 4.00 Credits
Advances in experimental and theoretical studies or laboratory and naturally-occurring high-termperature plasmas, including stability and transport, nonlinear dynamics and turbulence, magnetic reconnection, selfheating of "burning" plasmas, and innovative concepts for advanced fusion systems. Advances in plasma applications, including laser-plasma interactions, nonneutral plasmas, high-intensity accelerators, plasma propulsion, plasma processing, and coherent electromagnetic wave generation.
-
0.00 - 4.00 Credits
Analysis of methods for the numerical solution of the partial differential equations of plasma physics, including those of elliptic, parabolic, hyperbolic, and eigenvalue type. Topics include finite difference, finite element, spectral, particle-in-cell, Monte Carlo, moving grid, and multiple-time-scale techniques, applied to the problems of plasma equilibrium, transport and stability. Basic parallel programming concepts are discussed.
-
0.00 - 4.00 Credits
Develop skills, knowledge, and understanding of basic and advanced laboratory techniques used to measure the properties and behavior of plasmas. Representative experiments are: cold-cathode plasma formation and architecture; ambipolar diffusion in afterglow plasmas; Langmuir probe measurements of electron temperature and plasma density; period doubling and transitions to chaos in glow discharges; optical spectroscopy for species identification; microwave interferometry and cavity resonances for plasma density determination; and momentum generated by a plasma thruster.
