High Heat Flux Plasma Testing Facility

National Laboratory: 
Oak Ridge National Laboratory
Characterization Class: 
Extreme Environment Testing
Non-destructive examination
Processing/Manufacturing Class: 
Fabrication and synthesis
Thermo-mechanical processing
Description: 

The high-heat flux testing facility based on water-wall Plasma Arc Lamps (PAL) was designed for (a) materials testing; (b) Al and steel annealing; (c) infrared heating; and (d) cladding and coating deposition. The PAL systems use a 12,000°C plasma arc contained in a quartz tube cooled by a spiral water flow over the inside tube surface.

Capability Bounds: 

The maximum incident heat fluxes are 27 and 4.2 MW/m2 over areas of 1x10 and 9x12 cm2, respectively. The facility's testing chamber has been designed to accommodate large samples required for the high-heat flux testing of prototype components.

See LightMAT Capability Data Sheet at end of page for more details.

Unique Aspects: 

The very high heat fluxes available over wide areas are unique within the national laboratories and industry.

Availability: 

These facilities are available for various partnership arrangements with industry.
