Different samples of silica aerogel, which will be used as one of the radiators in the Ring Imaging Cherenkov of the LHCb experiment, were tested in a charged particle beam at CERN. Pions and protons with momenta ranging from 6 to 10 GeV/c traversed tiles of different thickness and different optical qualities, both hydrophobic and hydrophilic. Data were taken using as photodetectors up to four large diameter pad HPDs, produced at CERN. They showed an excellent signal to noise ratio, and provided coverage of up to 2/5 of the ring. Results on photon yield and resolution on the Cherenkov angle are discussed. Separation between pions and protons is demonstrated over the whole momentum range.
