I’ve looked into Zirconia before but the problem was finding a vendor to make the part. I asked for quotes on a hat with dimension about ~1/10 scale that LPP would need and no one could make it near theoretical density (the key to getting the other properties). That was a couple years ago so a vendor might exist now. It has many desirable properties compared to alumina other than the sensitivity to temperature. The data I found was zirconia cost more than alumina as well.

A liquid dielectric could be used outside of vacuum to insulate the parallel plates that feed the anode and cathode. In vacuum, how would you maintain the sleeve shape? I guess you could make a water fall but a liquid is more volatile and less survivable than a solid in the presence of a plasma.

Pulser: How thick can you coat the polymers? Are we taking microns or hundreds of microns? It would probably take mm to protect the underlying polymer.
