Functional foam coatings inside tubing and custom developed diamond ignition targets

The development of inertial confinement fusion targets requires new efficient ablator materials and characteristic temperature measurements during confinement. Here, an aerogel coating process is developed to coat inside spheres and cylinders. The characteristic emission spectrum of doped aerogel inside diamond targets is used as temperature gauge during confinement. Coatings inside metal cylinders confirmed the generality of the coating procedure. In addition artificial diamond is characterized which represents an interesting ablator material.
