Design of Aerosol Chambers for Atmospheric LIDAR Calibration

•Generate a stationary cloud of chemical agent simulants under the following conditions
–30 meters optical length
–Unobstructed optical path with a diameter of 3 m
–Spatially uniform in concentration (+/-15%)
–Temporally uniform (15 minute tests)
–Powders, vapor, liquid droplets
–Maintain negative pressure of -0.2 in. H2O (-50 Pa)
–Concentration of simulant outside chamber of 10-5or less
•Generate a known agent at specified concentration for calibration of LIDAR source & detector at a distance of 1-5 miles away.
•Chamber to be installed at Dugway Proving Ground
