The NASA Space Environment Simulation Laboratory
The Space Environment Simulation Laboratory (SESL) at the NASA Johnson Space Center operates a very large, low base pressure vacuum chamber that has been modified to be utilized as a plasma physics facility. Originally constructed as a thermal/vacuum test chamber for manned spacecraft, the facility was initially used for plasma physics research in 1977. Bernstein et al. (1975) developed a laboratory beam/plasma research program in the large vacuum chamber at the NASA Plum Brook Station, Sandusky, Ohio; following deactivation of that facility in 1975, the program was moved to the SESL chamber in 1977. Since then a variety of plasma investigations have been conducted here with the emphasis to date placed on programs studying specific space plasma physics phenomena of the lower inonsphere. Approximate simulation of the lower ionosphere has been achieved in terms of the neutral pressure, magnetic field strength, plasma density, and electron temperature. The chamber volume is sufficiently large that parameter scaling is unnecessary.
