Experience from the construction and installation of the HMPID CsI-RICH detector in ALICE

The construction and installation phases of the High Momentum Particle IDentification (HMPID) detector of the ALICE experiment were completed by summer 2006. The total active area of the detector is 11 m 2 . It represents the largest scale application of CsI photo-cathodes in RICH detectors to date. We will report on the production of the CsI photo-cathodes, the readout electronics, the Multi-wire Proportional Chambers (MWPCs) and the assembly and handling procedures needed to produce such a large detector.
