Abstract
high momentum particle identification detector (HMPID) covering about, 5% o f the ALICE central band region has been designed and prototyped. The detec tor consists of seven RICH modules with a proximity focusing geometry, cove ring 12 m(2) The very large density of hits on the detector (80/90 part/m(2 ) in the extreme cases) makes the recognition of the Cherenkov photon patte rns a complex and crucial task. A study of the pattern recognition strategy based on the Hough transformation in terms of particle identification effi ciency and particle contamination will be presented.
