Open full text 0 citations

Abstract

We have been developing a multipurpose aerogel Cherenkov counter which enables to identify charged particles at any environment such as a limited space and at high magnetic field.The device is composed of an aerogel radiator, a light guide made of 4 kinds of wavelength shifting (WLS) fibers and a small photo-device (PMT or SiPM).Cherenkov light emitted from the aerogel radiator is collected by the fiber light guide, and transferred to the both ends of the fiber by a total reflection condition.Therefore, the flexibility of the counter in shape with a small photo device can identify particles covering a large effective area.
