Abstract
The recent development of highly transparent aerogel has permitted its use as a Cherenkov radiator in a focused (non-Rayleigh-scattered) mod e. We report on the optical properties of this aerogel obtained by obs ervation of Cherenkov rings with single-electron-sensitive phototubes. The dependence on aerogel radiator thickness of the number of Cherenk ov ring hit points and background is shown and compared to expectation s. A 5 cm thick radiator of this aerogel will permit pi/K identificati on up to 20 GeV/c.
