Large-Scale Production of Airglass
Our work with silica aerogel started in 1976, as part of the preparations made for a new experiment at the CERN Intersecting Storage Rings. The spectrometer in the experiment should have a Cerenkov counter with a radiator of refractive index 1.050. Silica aerogel is the only material with a refractive index in that range. Our first attempts to produce aerogel were made at the Chemical Centre in Lund, where we used a small two litre autoclave. Since we were going to use aerogel as a Cerenkov radiator, our first and most important concern was to improve its transparency in the blue region of the spectrum.
