Abstract
We have produced 500 l of hydrophobic silica aerogel for the threshold-type Cherenkov detectors to trigger kaons in the momentum region of 0.5-2.0 GeV /c. The refractive index of the products is 1.034 with piece by piece varia tion of +/- 0.004. The transmission length is found to be 25 +/- 4 mm at 40 0 nm. The details of the production scheme and the characteristics of the p roduced silica aerogel are reported. We also describe our studies of the li ght collection schemes of the aerogel Cherenkov counters. (C) 2001 Elsevier Science B.V. All rights reserved.
