“…If necessary, these models may be extended and run as part of this work in addition to the ARMS model described above. These models include the University of Texas MHD magnetic nozzle code 31,33 , Ad Astra PT, a particle trajectory code for plasma exhaust modeling 50 [Ilin et al, 2004], and AARC Transport3d, a Boltzmann electron model with ion trajectories that uses 3d coil configurations. Depending on the outcome of the comparisons between the experimental results and the ARMS simulations, we will run these models to target specific physics questions.…”

We describe a proposed laboratory-experiment research program that will answer the fundamental question: What is the role of reconnection in opening and closing the solar magnetic field? While attacking this question, we will also address the most important, longstanding questions on magnetic reconnection, in all contexts: What determines the rate of reconnection, and whether or not it is bursty? How is the released energy partitioned between thermal, kinetic, and particle? Of course, it seems completely contradictory to use a 2 laboratory experiment to study an open system, because so far all laboratory plasmas have very solid walls. The pioneering feature of our program is that the experiments will be performed on the International Space Station (ISS). Only by going into space can we obtain the open domain that is absolutely essential for studying the observed solar/heliospheric phenomena. We describe a research program that will provide the instrumentation infrastructure, modeling and solar data expertise and initial scientific understanding required to develop the privately funded Aurora electric propulsion package with its VASIMR ® VF-200 high powered plasma source into a wall-less, orbiting ISS Space Plasma Laboratory (ISPL) national facility. The VAriable Specific Impulse Magnetoplasma Rocket (VASIMR ® ) is a high power electric spacecraft propulsion system, capable of I sp /thrust modulation at constant power [E. A. Bering, III, et al., "Observations of single-pass ion cyclotron heating in a transsonic flowing plasma," Phys. Plasmas, 17, 043509, doi: 10.1063/ 1.3389205, (2010).]. The VASIMR ® uses a helicon source to generate plasma. The plasma is leaked though a strong magnetic mirror to a second stage. In the second stage, the plasma is energized by a process that uses left hand polarized slow mode waves launched from the high field side of the ion cyclotron resonance. The single pass ion cyclotron heating (ICH) produces a substantial increase in ion velocity. Ad Astra Rocket Company (AARC) is planning to fly a plasma rocket experiment as a major element of the company's "Aurora" electric power and propulsion test platform on the ISS in 2014. The Aurora platform will support a dual-jet magnetic quadrupole 200 kW version of the VASIMR  plasma rocket (the VF-200). It will consist of two 100 kW parallel plasma engines with opposite magnetic dipoles, resulting in a near zero-torque magnetic system. The system will be available for basic plasma physics research in parallel with the testing of the VF-200 engine performance as a high power electric propulsion system. The Aurora package would thus become a National Plasma Physics Laboratory (the ISPL) suitable for plasma physics studies in an open, wall free near-Earth orbital laboratory environment. An ISS arm deployed instrument package similar to the Plasma Diagnostics Package used on STS-3 in conjunction with the OSS-1 experiment and STS-51F in conjunction with Spacelab 2 has been proposed to NASA. The Aurora Plasma Diagnostics Package (APDP) will carry La...

“…Computational models of wave-driven plasma sources have found important applications in plasma processing of materials, semiconductor processing and surface modification processes [3]. Plasma-wave modelling is also an important element in the development of advanced space propulsion systems [4]. The computational physics models developed for fusion applications have been instrumental in advancing research in these areas.…”

Global-wave solutions with self-consistent velocity distributions in ion cyclotron heated plasmas

et al. 2006

Global wave solutions with self-consistent velocity distributions are calculated for ion cyclotron heating in non-Maxwellian plasmas. The all-orders spectral algorithm (AORSA) global wave solver is generalized to treat non-thermal velocity distributions arising from fusion reactions, neutral beam injection and wave driven diffusion in velocity space. Quasi-linear diffusion coefficients are derived directly from the wave electric field and used to calculate ion velocity distribution functions with the CQL3D Fokker–Planck code. Alternatively, the quasi-linear coefficients can be calculated numerically by integrating the Lorentz force equations along particle orbits. Self-consistency between the wave electric field and resonant ion distribution function is achieved by iterating between the global-wave and Fokker–Planck solutions.
