Abstract | In order to study the feasibility of large scale multicell counters, two prototypes with respective detection area 80*40 cm/sup 2/ and 65*31 cm/sup 2/ were constructed. The Cerenkov light produced in silica aerogel of refractive index n=1.03 and diffused in a well optimized box was detected with five quantacon photomultipliers. Results of beam tests concerning the aerogel thickness, the diffusing material and box shape, the influence of the incident particle position and the momentum threshold curves for pi , K and p are presented. The final design of a multicell detection system is given. (6 refs). |
