Description
The construction and installation phases of the High Momentum Particle
IDentification detector (HMPID) of the ALICE experiment were completed by
summer 2006. The HMPID has been designed to identify charged pions and
kaons in the range 1 < pt < 3 GeV/c and protons in the range 2 < pt < 5
GeV/c. The total active area of this detector is 11 m 2 and represents the
largest scale application of CsI photo-cathodes in RICH detectors. We will
report on the production of the CsI photo-cathodes and their performances,
the readout electronics, the mwpcs and the assembly and handling
procedures needed to produce such a large detector. As well, we will present
performance results achieved in test beams and the main difficulties
encountered during the construction process.
