Ground-Based Investigation of Near- Earth Space Plasma Processes in the NRL Space Physics Simulation Chamber

Introduction: The NRL Space Physics Simulation Chamber Laboratory conducts a broad-based research program addressing near-Earth space plasma physics. The unique Space Chamber device (shown in operation in Fig. 1) produces large-volume, steady-state, spacelike plasmas with conditions scaled to match various ionospheric and magnetospheric regions of interest. The program includes basic research illuminating the underlying physics driving key space plasma processes and applied research for understanding plasma effects on spacecraft systems, testing spacecraft hardware, and development of innovative plasma sensors.
