Gauntlet 2001 SF6 Tracer Experiment

Location and Date:

Dugway Proving Ground, UT, April, 2001.


Determine dispersion characteristics of SF6 at Dugway Proving Ground, UT, using mobile real-time tracer analyzers.

Summary and Conclusion:

Seven SF6 tracer tests were conducted at Dugway Proving Ground by the Field Research Division. A mix of daytime and nocturnal tests were conducted. The tests consisted of both releasing and measuring the SF6 with real-time mobile analyzers. SF6 was continuously released for four hours during each test at a nominal rate of 70 kg/hr. Daytime conditions caused the SF6 to dilute such that in most cases, the material was below detection limits at distances greater than 50 km. However, at night the material was detected at distances approaching 80 km. Local topography influenced the trajectory of the material, as did the strength of the inversion. The data collected can be used to verify many different types of transport and dispersion models.
