Fig. 1-1 p. 13 a) View of the prototype along the beam direction looking downstream, b) side view of the prototype. Three slabs of aerogel (4.5x4.5x1.5 cm3) were used. The WLS thickness was 0.3 cm.
Fig. 1-2 p. 14 Spectrum of detected photons with detector in-line with the beam but containing no aerogel. The amount of photons observed is due to Cerenkov light produced in the WLS. The first peak corresponds to the pedestal.
Fig. 1-3 p. 15 Spectrum of detected photons, produced in a 9 cm aerogel Cerenkov radiator, coupled to a 0.3 cm thick WLS. We estimate that the total number of photons detected, per event is ~18.
