Tender Details

Description

Opportunity:

Lawrence Livermore National Laboratory (LLNL), operated by the Lawrence Livermore National Security (LLNS), LLC under contract no. DE-AC52-07NA27344 (Contract 44) with the U.S. Department of Energy (DOE), is offering the opportunity to enter into a collaboration to further develop its high-voltage insulator having multiple materials.



Background:

High voltage applications utilize insulator materials that can handle mechanical stresses as well as high intermittent heat loads. Combining materials, segmenting them in a device, can take advantage of differing material properties for higher tolerances and an overall better performance.



Description:

The approach is to build a high voltage insulator consisting of two materials: Poly-Ether-Ether-Ketone (“PEEK”) and Machinable Ceramic (“MACOR”). PEEK has a high stress tolerance but cannot withstand high temperatures, while MACOR has high heat tolerance but is difficult to machine and can be brittle. MACOR is used for the plasma-facing surface, while PEEK will handle the stresses and high voltages. This approach also uses a precision-machined threaded insulator design with gaskets and grease to seal the parts.



Advantages/Benefits:

Allows mating two unlike materials to take advantage of differing physical properties Does not require epoxy that can trap gas in the parts, require curing, and may need additional pieces to align the parts The thread and gasket designs make the track length across the material long enough for the failure modes to arc through the material

Potential Applications:

High-voltage insulators with plasma facing components (e.g., Dense Plasma Focus, Z-machine) Plasma rail-gun construction

Development Status:

Current stage of technology development: TRL 3 (Analytical and experimental critical function and characteristic proof of concept)
