12V SPACE CHAMBER
Published September 24, 2008
The 12V Chamber is a 12-foot-diameter by 35-foot-high thermal vacuum test facility with solar simulation capability. The facility contains a full liquid nitrogen thermal shroud and has an optional gaseous helium inner liner that can be cooled down to 10 degrees Kelvin. The solar simulator is an off-axis system with xenon arc lamps that uses integrating assemblies to collimate a uniform, 1-solar constant beam over an 8-foot-diameter by 8-foot-high test volume. The chamber can also be configured for electric propulsion thruster plume analysis and integration effects testing.
Thermal Control: Chamber is completely lined with a liquid nitrogen shroud that can provide thermal conditions down to 77 degrees Kelvin. Optional 10-degrees Kelvin gaseous helium liner available upon request.
Vacuum Range: ≤1x10-7 Torr (with gaseous helium shroud) to local atmospheric pressure.
Working Volume: 12-foot diameter x 35-foot high.
Pumping System: Mechanical roughing pumps, blowers, and single 36-inch diffusion pump, all with cryogenic traps. Upgrade to clean cryogenic high vacuum pumps planned.
Loading: Horizontal: 6-foot manway. Vertical: 10-foot cap at top of chamber.
Cold Wall: Full liquid nitrogen cryogenic shroud. Optional 10-degrees Kelvin gaseous helium liner available upon request.
Special Features: Quartz xenon arc lamp solar simulator system.
Data: All facility data time tagged and archived.
Work Areas: Test customer offices available. Limited hardware storage available.
Solar Simulation: Off-axis system with xenon arc lamps that use an integrating lens assembly to collimate a uniform, 1-solar constant beam over an 8-foot-diameter by 8-foot-high test volume.
Electric Propulsion: In the EP configuration, the cell pressure during thruster operation can be maintained at or below 10-6 Torr, with a xenon pumping speed exceeding 2,000,000 liters/sec. Plume Diagnostics with Langmuir Probes and Radio Frequency Horns are available.
