N2 - 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 variation of ±0.004. The transmission length is found to be 25±4 mm at 400 nm. The details of the production scheme and the characteristics of the produced silica aerogel are reported. We also describe our studies of the light collection schemes of the aerogel Cherenkov counters.
