Tests of a silica aerogel cerenkov detector to be used in the european hybrid spectrometer

An 18 module Ceienkov detector with a total sensitive area of 2.3 m2 having silica aerogel as radiator is being tested in a particle beam at CERN PS. The modules having a sensitive area of 23 X 55 cm2 give typically a Cerenkov signal for (3= 1 particles of 12 photoelectrons for silica aerogel of refractive index 1.03 and a thickness of 15 cm. © 1981 IOP Publishing Ltd.

Anomalous transport in plasmas

The application of stochastic methods to the problem of particle and energy transport in turbulent plasmas is briefly reviewed. The "classical" Corrsin approximation is shown to be valid only in the limit of weak turbulence. The recently developed method of decorrelation trajectories is applicable over the whole range of turbulence intensities and yields the correct asymptotic behavior in the limit of very strong turbulence (subdiffusion). © 2004 Wiley Periodicals, Inc.
