A processing technique for production of fused silica for radomes and like elements is described. The processing technique includes forming a mixture of milled silica having an average particle size of about 1 to 5 microns, and a colloidal silica. This mixture is processed to form fused silica having substantially high strength.

Fused silica and method of manufacture

An X-ray tube including a tubular envelope having therein an anode target provided with a surface portion made of X-ray emissive material and with another surface portion coated with amorphous carbon material, and an electron emitting cathode disposed to beam electrons onto the surface portion of the target made of X-ray emissive material.

X-Ray tube target having pyrolytic amorphous carbon coating

An X-ray tube including a tubular envelope having therein an X-ray target comprised of a support body made of a first material and provided with a composite surface layer comprising a controlled gradient of a second material disposed in the first material, one of the materials being an X-ray emissive material and the other of the materials being a heat absorbent material, and an electron emitting cathode disposed to beam electrons onto a focal spot area of the composite surface layer.
