high momentum particle identification detector (HMPID) covering about, 5% of the ALICE central band region has been designed and prototyped. The detector consists of seven RICH modules with a proximity focusing geometry, covering 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 patterns a complex and crucial task. A study of the pattern recognition strategy based on the Hough transformation in terms of particle identification efficiency and particle contamination will be presented.

Abstract
high momentum particle identification detector (HMPID) covering about, 5% of the ALICE central band region has been designed and prototyped. The detector consists of seven RICH modules with a proximity focusing geometry, covering 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 patterns a complex and crucial task. A study of the pattern recognition strategy based on the Hough transformation in terms of particle identification efficiency and particle contamination will be presented.File in questo prodotto:
